  SUMMARY: 
  ... We are in a law school today, so let me start, as we do in law schools, 
  with a case. ... Thus she was not married, because both did not consent to the 
  same thing, and that is necessary for marriage. ... If any free man takes a 
  slave girl in matrimony, and they were joined by mutual consent, he does not 
  have license to send her away, except on account of fornication [cf. Mt. 
  19:9]. ... It is the book, and the teaching method that it embodies, that have 
  made Master Gratian celebrated and best demonstrate the character of the first
  Catholic law school. ... There is at work in the 
  hypothetical a second social fact not present in our world: society is divided 
  into free and slave. ... If a slave may marry, why is a mistake as to a 
  spouse's status as a slave different from a mistake as to his wealth, his 
  integrity, his mental capacity, or his chastity? You may say that in a society 
  where slavery exists, the mistake is of such a social magnitude that the 
  mistaken spouse deserves a break; but it's not too difficult to think of other 
  cases - say the spouse is a homosexual - where an analogous argument can be 
  made and the category of a status mistake asserted. ...   
  
  TEXT: 
   [*1189]  
  
  We are in a law school today, so let me start, as we do in law schools, with a 
  case. The case reads as follows: 
  
  CASE TWENTY-NINE 
    
  Gratian: A noblewoman learned that another noble's son sought her in marriage. 
  She consented. But a non-noble of servile condition offered himself under 
  first man's name and took her as wife. Her first choice at last arrived to 
  seek her in marriage. She complained that she had been deceived and wanted to 
  marry the first man. The questions here are: 
  
  First, were they married? 
  
  Second, if she first believed a man was free, and later discovered he was 
  servile, could she lawfully leave him forthwith? 
  
  QUESTION I 
    
  Gratian: That they were married is proved this way. Marriage is the union of a 
  man and woman keeping an undivided way of life [Instit. 1 9.1.]. Mutual consent 
  makes marriage. Those, therefore, who join in order to keep an undivided way 
  of life, consenting to each other, are married. 
  
  1. Reply to this: Consent occurs when two or more perceive the same thing
  [Dig. 2.14.1]. He who is in error, however, does not perceive the same thing. 
  So he cannot consent - that is, agree to the same thing as another. So, one 
  who errs does not consent. Thus she was not married, because both did not 
  consent to the same thing, and that is necessary for marriage. 
  
  Someone errs in the same way when he is ordained by someone he believes to be 
  a bishop, but who is really a layman. He is not ordained and  [*1190]  must 
  still be ordained by a bishop. She erred in his way and thus was not united in 
  marriage, but rather yet to be united. 
  
  2. On the contrary: Not every error eliminates consent. One who takes a wife, 
  thinking her a virgin, or one who takes a prostitute, thinking her chaste, 
  errs because he thinks a corrupted woman is a virgin, or because he accounts a 
  prostitute as chaste. But did they not consent to these women? Does either man 
  have the option of sending the woman away and taking another? 
  
  In fact, not every error excludes consent. Error as to person is one thing, 
  error as to fortune another, error as to condition another, and error as to 
  quality yet another. Error as to person occurs when one thinks someone is 
  Virgil (St. Gall, p. 170: Stichus) when he is Plato 
  (St. Gall: Pamphilius). Error as to fortune occurs when one thinks someone is 
  rich when he is poor, or conversely. Error as to status occurs when one thinks 
  someone is free when he is of servile status. Error as to quality occurs when 
  one thinks someone is good when he is bad. Error as to fortune or quality does 
  not exclude consent to marriage. 
  
  
  If one agrees to sell a field to Marcellus, and Paul later arrives saying he 
  is Marcellus and buys the field from him, did he agree on the price and sell 
  the field to Paul? 
  
  (Digest 6.1.72)  Also, if one promises to sell me gold, but gives me yellow 
  ore in place of gold, and thus deceives me, did I consent to the yellow ore? I 
  never wanted to buy yellow ore, and at no time did I consent to it, because 
  consent cannot exist without the will.
  
  (Digest 18.1.9 and 13.7.1)
  
  Just as error as to the matter here excludes consent, so error as to person 
  does in marriage. She did not consent to this man, but to the man she thought 
  this man was.
  
   
  
  3. Objection: Jacob did not consent to Leah but to Rachel [Gen. 29:9-30]. He 
  served seven years for Rachel. So, when Leah was put in with him, but he did 
  not know it, there would have been no marriage if error as to person excluded 
  consent. For, as was said, he did not consent to her, but to Rachel. 
  
  Response: Antecedent consent is one thing, subsequent consent another. 
  Antecedent consent would be consent to both an undivided way of life and to 
  fleshly intercourse. Subsequent consent occurs when, after sexual relations 
  during concubinage or fornication, they both consent to the former as well. 
  Antecedent consent did not make Jacob and Leah husband and wife, but 
  subsequent consent did. 
  
  But they are not to be adjudged fornicators because of their intercourse, for 
  he knew her with marital affection, and she rendered the debt to him with 
  marital affection, thinking she was rightly joined to him, on account of the 
  Law of the First Born and her father's command. 
  
  4. A later authority [C. 34 qq. 1 & 2 c. 6] proves that error as to person 
   [*1191]  sometimes excuses. When a wife's sister goes to the bed of her 
  sister's husband (both the sister and the husband being unaware), and the 
  sister's husband knows her, she loses perpetually the right of marriage, but 
  he who knew her in ignorance is excused. 
  
  This is also proved in another way. The devil sometimes transforms himself 
  into an angel of light [cf. 2 Cor. 11:14], but this error poses no danger to 
  one who believes him to be good when he is posing as good. If, then he asked 
  an unlettered person whether he wished to share his blessedness, and the 
  latter replied that he wanted to associate with him, can one say he chose to 
  associate himself in devilish damnation? Did he not, rather, choose to 
  participate in eternal bliss? 
  
  Also, if a heretic came to some Catholic and convinced him to accept his 
  beliefs as those of Augustine, Ambrose, or Jerome, did he consent to accept 
  the man's belief? Should one not say rather that he consented, not to the 
  heretical sect, but to the integral Catholic Faith that the heretic falsely 
  claimed to present? 
  
  
  Because this woman was deceived by error, she plainly did not consent to the 
  latter man, but to the former man he falsely claimed to be. 
  So she is not his 
  wife.   [Noonan's 
  Conclusion to the First Question]
  
  
  5. Error as to fortune or quality does not exclude consent. When one accepts 
  the prelacy of a church he believes to be very rich, and it is less so, 
  although he is in error as to fortune, he still cannot renounce the prelacy he 
  accepted. Likewise, one who marries a pauper thinking him wealthy cannot 
  renounce this relationship, although she did err. 
  
  Likewise, error as to quality does not exclude consent. When one buys a field 
  or a vineyard, supposing it very fruitful, but errs as to the quality of the 
  property and buys an infertile one, he still cannot rescind the sale. 
  Likewise, one who takes as his wife a prostitute or seduced woman, thinking 
  her chaste or a virgin, he cannot send her away and take another [om. SG, sed 
  non Gratianus I].
  
   
  
  QUESTION II  
    
  Gratian: The second question concerns condition. Can a woman lawfully send 
  away a man she thought to be free if afterwards she discovers he was servile? 
  Many arguments prove that the woman cannot lawfully leave the slave. In Christ 
  Jesus, there is neither Jew nor Greek, slave nor free [cf. Col 3:11]. Nor is 
  there in Christian marriage, for the same law rules all in the Faith of 
  Christ. 
  
  The Apostle said to all without discrimination [cf. I Cor. 7:36], "Whoever 
  wishes to marry, let him marry in the Lord." And again [I Cor. 7:39], 
   [*1192]  "Let a woman marry whom she pleases, only let it be in the Lord." He 
  does not command a free woman to marry only a free man, or a slave girl only a 
  slave, rather everyone may marry whomever he wishes, provided it is in the 
  Lord. 
  
  Also, Pope Julius: 
  
  C. 1. 
    
  Slaves can lawfully contract marriage. There is one Father in heaven for all 
  of us. Each of us, rich or poor, free and slave, will equally render an 
  account for himself and his soul. Therefore, we do not doubt that all, 
  whatever their condition, are under one law before the Lord. If, however, all 
  are under one law, then neither a free man nor a slave can be sent away, once 
  he is joined in marriage. 
  
  Also, Pope Zacharias: 
  
  C. 2. 
    
  A man cannot lawfully send away a slave girl he has taken in matrimony. If any 
  free man takes a slave girl in matrimony, and they were joined by mutual 
  consent, he does not have license to send her away, except on account of 
  fornication [cf. Mt. 19:9]. There shall be one law in all things, for the man 
  and for the woman [cf. C. 29 q. 2 c.5]. 
  
  Also, Pope Julius: 
  
  C. 3. 
    
  Lawful marriage certainly exists between a master and a freed woman. Some ask 
  whether or not it is a lawful marriage if someone has given his slave girl her 
  freedom and united with her in matrimony. We, therefore, resolve this ancient 
  doubt and declare such marriages lawful. If marriage is entirely made by 
  consent, there is nothing impious or contrary to the law in such a union. Why 
  would we think that the said marriage should be prohibited? 
  
  Part 2 
    
  Gratian: Reply to the foregoing: It is not denied that a free woman can 
   [*1193]  marry a slave, but, if his servile condition was unknown, he can be 
  freely put away when his servile status is discovered. What the Apostle [1 Cor. 
  7:39] and Pope Julius [C. 29 q. 2 c. 1] say should be understood to concern 
  those whose condition was known to both. 
  
  The woman did not know this man's condition. Therefore, these authorities do 
  not compel her to stay with him, so she is free to leave or stay with him. 
  
  Hence the Council of Verberie, at which King Pepin was present, legislated, at 
  c. 6: 
  
  C. 4. 
    
  On one who takes a slave girl as a wife thinking her to be free. If any free 
  man takes another's slave girl as his wife, thinking that she is free, and 
  this woman is later discovered to be enslaved, he may redeem her from slavery, 
  if he can. If he cannot, he may take another wife, if he wishes. But if he 
  knew she was a slave, and still thought highly of her, he must later keep her 
  as his lawful wife. A free woman must do likewise with another's slave. 
  
  Also, from the same, c. 8: 
  
  C. 5. 
    
  A woman cannot lawfully send a man away if she married him knowing he was a 
  slave. If a free woman takes a slave, knowing him to be a slave, let her keep 
  him, for we all have the same Father in Heaven. There shall be one law for the 
  man and for the woman [cf. C. 29 q. 2 c. 2]. 
  
  Also, Gregory, [in [Register], V, I, to Bishop Fortunatus]: 
  
  C. 6. 
    
  One who has proved himself free at law cannot be sent away because of servile 
  status. The bearer of this letter came here last year with her mother, 
  compelled by litigation. Your Fraternity has prudently discovered that her 
  husband, your priest, dismissed her from union with him because of her servile 
  status. The woman and her mother assert that, in this case, you have promised, 
  if she can with God's help prove that she is free, you will restore her 
  marriage. 
  
   [*1194]  Let Your Fraternity know that, with God the Author of Freedom's 
  guidance, she has proved that she is free, without any suspicion of slavery. 
  Now that you know this, we order you to restore her to her husband without 
  delay, and to prevent him from advancing other reasons to eject her. If you, 
  contrary to our expectations, fail to do this, or he delays receiving her, 
  know that we will correct it with severe punishment. 
  
  Gratian: When it says [C. 29 q. 2 c. 5], "Knowing him to be a slave," it is 
  understood that, if she did not know he was a slave, she would not be 
  compelled to stay with him. So, when one is deceived as to person or 
  condition, one need not adhere to the one through whose fraud one was 
  deceived. 
  
  But, if she received a free man, and he, as an excuse to withdraw, made 
  himself someone else's slave, he cannot send his wife away, nor can she be 
  enslaved on account of the marriage bond. 
  
  Hence in the Council of Trebur: 
  
  C. 7. 
    
  A man who received a woman while he was free may not abandon her by means of a 
  deceitful status change. It has been reported to the Holy Synod that a certain 
  free man received a free woman as his wife and, after procreating children, he 
  made himself another's slave to procure a divorce. It is asked if he must keep 
  the woman, and, if he does keep her, must she also be enslaved, in accord with 
  secular law. 
  
  It is decided that he may not send the woman away. Nor, in accord with 
  Christ's law, should the woman be enslaved, because he made himself a slave 
  without her consent, and she took him as husband when he was free. 
  
  Gratian: There is also a question as to whether there is a marriage if one 
  man's slave takes another's slave girl. 
  
  Legislation of the [Second] Council of Chalons-sur-Saone, [c. 30], treats 
  this: 
  
  C. 8. 
    
  The authority of their masters cannot annul the lawful marriages of slaves. We 
  have heard that certain men, with amazing presumption, annul the lawful 
  marriages of their slaves, ignoring the words of the Gospel [Mt.  [*1195]  
  19:6], "What God has joined together, let no man put asunder." So we declare 
  that the marriages of slaves cannot be annulled, even if they have different 
  owners. Rather, preserving the unity of marriage, let them serve their 
  different owners. This is to be observed when the marriage is a legal union 
  with the owners' consent.[su' n1 '] 
  
  The case comes from the casebook of the law school of the University of 
  Bologna. The first version of the book was in use by 1139. In round numbers, 
  1150 may be taken as a time when it was current. It is not only an old 
  casebook. It is a remarkably durable one. It was a major resource for canon 
  law until 1917 when the Code of Canon Law was issued by Benedict XV. It had a 
  run of not quite 800 years. As the author of a casebook myself, I'd be happy 
  if my book would last one-tenth this time. 
  
  Why was it so durable, so significant? Not exactly because of the reputation 
  of its reputed author, Gratian. No one knows who Gratian was. The Camaldolese 
  monks, who in the seventeenth century wrote the history of the University of 
  Bologna, claimed Gratian was a Camaldolese. He has also been identified as a 
  bishop and as a layman. He remains a mystery, known only by his remarkable 
  book. It is the book, and the teaching method that it embodies, that have made 
  Master Gratian celebrated and best demonstrate the character of the first
  
  
  
  Catholic law school. 
  
  It is, then, not to the teacher but to his book and the case taken from it 
  that I turn to show what a Catholic law school - the 
  preeminent Catholic law school - was like in 1150, the 
  point at which Bologna begins to produce men trained in canon law. 
  
  You will note right away that the case is a hypothetical. The term was not in 
  vogue, but the putting of hypotheticals as a teaching device is standard in 
  the thirty-six cases that form the heart of Gratian's book. Like many law 
  professors' hypotheticals, this one is a bit strained in order to bring out 
  the points the professor wants to make. It is strained but not fantastic. It 
  does make one assumption that is contrary to life in our day but not to life 
  then: that a woman would want to marry a man she hadn't seen. Clearly in 1150 
  we are in a society where the nobility does go in for arranged marriages, the 
  arrangements can be made sight unseen, and consequently there is room for 
  deception when the expected spouse is replaced by an imposter. 
  
  There is at work in the hypothetical a second social fact not present in 
   [*1196]  our world: society is divided into free and slave. Being a slave is 
  not simply a social fact but a legal one. The status of a slave is, by law, a 
  status where most of the legal attributes of personhood are absent. This state 
  of affairs is the legacy of over one thousand years of Roman law and the 
  universal acceptance of slavery is part of the social structure. 
  
  The hypothetical is posed with seven selected facts. The woman is of noble 
  birth. She accepts a specific proposal of marriage. An imposter appears, who 
  takes her as a wife. The real fiance arrives. She wants to back out of her 
  mistaken consent. She now also discovers that the imposter was a slave. On 
  this basis two legal questions are posed with great clarity: (1) Was she 
  married? and (2) Discovering that the man is a slave, is she free to disavow 
  the marriage? 
  
  The discussion opens by reference to Roman law, always an important element in 
  a Catholic European law school. The teaching of what was a new academic 
  subject, canon law, had evolved at Bologna from the teaching of Roman law that 
  had begun by 1100. n2 Theology is a background assumption. The canon law 
  teacher was a theologian on his way to becoming a lawyer. n3 Theology says 
  that a marriage is indissoluble. Theology does not say what a marriage is. To 
  answer that question, the teacher and his students have to turn to human 
  experience. The most accessible experience is incorporated in the familiar law 
  of imperial Rome. Gratian draws on this law in two ways, to define marriage as 
  a joining "in order to keep an undivided way of life" and to announce that 
  marriage is made by mutual consent. n4 These foundational propositions plunge 
  him into his first problem: consent, as Justinian's Digest declares, requires 
  that those consenting "perceive the same thing." n5 If a party is in error as 
  to the thing perceived, there cannot be consent. The woman, mistaken as to the 
  man she was marrying, is not married. A somewhat different case is thrown in 
  as a reinforcing analogy: a layman ordained by a man he thinks is a bishop 
  remains a layman if in fact the ordainer is not a bishop. 
  
  Now Gratian complicates the argument, as law professors will. With  [*1197]  
  out citation of authority, he suggests that if a man marries a woman in error 
  as to her chastity, he may not get out of the marriage on the ground of 
  mistake. Following up the suggestion, Gratian announces that there are four 
  different kinds of error. Where he gets these categories from is not clear; he 
  imposes them as obvious; and, of course, like many astute law professors, he 
  has already inserted his solution in his categories. 
  
  The four kinds of error are as to person, fortune, status, and quality. As is 
  apparent on very little inspection, these are overlapping and not very stable 
  categories. They invite debate. They are the tools that Gratian appears ready 
  to use. However, he moves to two commercial examples, one of which involves 
  fraud. If you intend to buy gold and are given yellow ore instead, you did not 
  consent to the purchase. The mistake is as to matter. It vitiates your 
  consent. The sudden movement of Gratian's thought goes to an example which is 
  treated as offering a decisive analogy with mistake as to person - this sudden 
  movement is as though you were in the classroom hearing a professor brimming 
  with ideas replace one idea with a better one that has just come into his 
  mind. 
  
  The mind of the law professor, who is also well-read in Scripture, then 
  wanders off to a biblical case set out in Genesis. Jacob has agreed to serve 
  Laban seven years, at the end of which time Laban will give him his younger 
  daughter Rachel in marriage. Jacob has looked both girls over and found Rachel 
  distinctly better looking than her elder sister, Leah. As the story goes in 
  Robert Alter's excellent modern translation: 
    
  and Jacob served seven years for Rachel, and they seemed in his eyes but a few 
  days in his love for her. And Jacob said to Laban, "Give me my wife, for my 
  time is done, and let me come to bed with her." And Laban gathered all the men 
  of the place and made a feast. And when evening came, he took Leah his 
  daughter and brought her to Jacob, and he came to bed with her. n6 
    
  The story assumes, but does not say, that after the feast Jacob was too drunk 
  to know the difference between two sisters he'd seen for seven years and whose 
  looks he had enthusiastically compared. In the morning he's naturally upset. 
  Laban explains that "it's not done thus in our place, to give the younger girl 
  before the firstborn," but he stipulates that if Jacob finishes out the bridal 
  week with Leah he can have Rachel, too. n7 Jacob agrees. In this polygamous 
  world, a second wife is no problem. In fact he has five sons from her. 
  
   [*1198]  What is the relevance to Gratian of this tale which, in passing, 
  conveys a recognition of both beauty and love as major motives for marriage, 
  approves parental disposal of daughters in marriage, takes polygamy in stride, 
  and is ambiguous about Laban's deception? In a later case, Gratian will defend 
  the proposition that marriage must be made by the free will of the man and 
  woman. Here he doesn't bother to look at the parental role, nor does he pause 
  to examine the consent a blind-drunk Jacob could have given to Leah. He picks 
  up the story as a kind of biblical ornament to his legal exposition and 
  imagines a student asking how Jacob was married to Leah when he thought he was 
  in bed with Rachel. The question is answered with ease by creation of two new 
  categories, antecedent consent and subsequent consent. After Jacob acquiesced 
  in Laban's request to stay the bridal week with Leah, he is assumed to have 
  knowingly consented to her as a wife. One side problem remains: when they 
  first had intercourse, weren't they fornicators? It's a question a mischievous 
  or zealous student might well raise. Gratian's answer is no. Jacob thought she 
  was his wife - he treated her "with marital affection," a key canonical 
  concept describing the state of mind and feeling distinguishing conjugal 
  relations from lust. As for Leah, she thought she was doing the right thing. 
  The digression permits the teacher to touch on the immorality of sex without 
  marriage. 
  
  A case of incest rounds out the digression. A sister creeps into the bed of 
  her sister's husband. The assumptions have to be that the wife is away and 
  that, again, we have a husband too soused to know the difference. The 
  lascivious sister-in-law is punished by being denied the right to marry 
  anyone; the husband is excused because of his ignorance. This case doesn't 
  materially advance discussion of the hypothetical. It seems to enter the 
  professor's mind by a kind of gossipy association of ideas, one story of 
  ignorant mistake leading to another such story dealt with by law. 
  
  The teacher returns to the central question of mistake as to person, and the 
  teacher now shows his interest in, and knowledge of, theology. He knows from 
  St. Paul that the devil transforms himself into "an angel of light." n8 
  Suppose, so transformed, the devil asks an unlettered one if he wishes to 
  share his happiness, does the answer Yes mean an acceptance of hell? 
  Similarly, if a heretic convinces a Catholic that the heretic's beliefs are 
  those of Augustine, Ambrose, or Jerome, does the Catholic consent to the 
  heresy or to what the Catholic believes to be the Catholic faith? These 
  questions are rhetorical. They emphasize that error can de  [*1199]  stroy 
  true consent. They are not strikingly apropos to the case at hand, branching 
  off as they do in the direction of good faith as a defense to heresy. As used 
  by Gratian, the questions are meant to reinforce the argument that the woman 
  is not married. 
  
  There is, however, a further wrinkle, illustrated by both ecclesiastical and 
  secular law. If a priest accepts a prelacy thinking that it is well-endowed 
  and it is not, he cannot back out. If you buy a field or vineyard thinking it 
  is very fruitful and it turns out to be infertile, you are stuck. These errors 
  are labelled errors of "fortune or quality." n9 By the same token, Gratian 
  moves quickly to say, if a woman thinks a man is rich and he turns out to be 
  poor, she can't get out of the marriage. It's just the same, he says again, as 
  to a man who think he's married a virgin, and the bride turns out to have been 
  seduced or to be a prostitute. No authority is cited for any of these 
  propositions: ecclesiastical, commercial, or matrimonial. They are put forward 
  as matters of common knowledge and acceptance. 
  
  After all these illustrations, analogies, distinctions, and categories, what 
  is Gratian's answer to his first question: Was the woman married to the 
  imposter? One way to read him is to go back where he says error as to person 
  is different from error as to fortune. On that reading the woman is not 
  married when she made a mistake as to person. But another reading is possible: 
  Gratian has left the matter open. He has no decisive summing up. His final 
  illustrations are of serious mistakes that do not vitiate consent. He offers 
  no principled argument for his different categories, which could collapse into 
  each other. He has started an argument. 
  He has left his students to finish it.
  
  
  
  Let's look at Question II. It takes us at once into a fundamental 
  sub-question: can a slave ever marry? As to that question, Roman law had a 
  simple answer: no. A slave did not have the rights and capacities of a person. 
  If a slave had a sexual relation with someone, it was "a thing," nothing more. 
  You will observe that Gratian, so careful to cite the Institutes and Digest of 
  Justinian in answering Question I, makes not the slightest acknowledgment of 
  Roman law here. "The Church lives by Roman law"--was a maxim current in 
  Gratian's day. n10 But the maxim does not always hold. Without apology, 
  without argument, with the sovereign freedom of one who is the expositor of 
  the law of the Church, he  [*1200]  will decide the question of slave marriage 
  uninhibited by secular law. 
  
  His first thought goes very far, so far that, if he sticks to it, the status 
  of the slave disappears in canon law. In Christ Jesus, as St. Paul has 
  instructed the Colossians, there is neither Jew nor Gentile, neither slave nor 
  free. n11 If there are no slaves in Christ, how can slave status be a bar to 
  matrimony? Gratian enlarges on the implications of his citation of St. Paul by 
  two more quotations from the same authority speaking to the Corinthians 
  specifically about marriage and setting no restriction as to the freedom of 
  all Christians to marry. The scriptural foundation of Gratian seems solid. 
  
  Gratian proceeds with what is the common way of answering questions in his 
  book - not by the free ranging discussion he engaged in answering Question I, 
  but by citing a series of legal authorities arranged in short chapters with a 
  summarizing headnote at the start of each chapter. He begins with three 
  rulings by popes that slaves may marry validly. One of the rulings 
  acknowledges an "ancient doubt" on this point. n12 None of them acknowledge 
  that they go in the teeth of Roman law. They were, in their time, 
  revolutionary without even mentioning the authority they repudiated. In 
  Christ, the slave can receive the sacraments, the slave is eligible for 
  salvation, the slave is a human being. On these capital points Christian law 
  is firm. Gratian, taking the citations from earlier collections of papal 
  pronouncements, does not attempt to date them or to provide any historical 
  context. Without hesitation, he sees the rulings as the undisputed canon law. 
  The law as papally proclaimed even encompasses the delicate case of a man 
  marrying his own slave, although it is assumed in the case presented that the 
  man will first emancipate and then marry her. 
  
  In the face of these sweeping authorities, Gratian creates a doubt by 
  returning to the hypothetical where the free person did not know of the 
  other's servile state. This ignorance, he maintains, changes the situation. 
  The woman is free to stay or leave. 
  
  In support of this qualification is a chapter citing a French church council, 
  marked by the irrelevant detail that King Pepin was present. The authority is 
  local. It's enough for Gratian. The next chapter from the same council 
  supports the general rule, implicitly applying it only where there was 
  knowledge of the spouse's slavery. Chapter six, which follows, is a ruling by 
  a major authority, Pope Gregory the Great. It as  [*1201]  sumes that priests 
  may marry. It orders a bishop to make a priest of his diocese and to take back 
  as a wife a woman he had dismissed because he thought she was a slave. The 
  pope rules that he, the pope, has found her to be free, so the priest must 
  have her back. The implication is that, if she had been found to be a slave, 
  she would have lost her marriage. The placing of this decision in Gratian 
  implicitly reads the decision as one where her husband married her believing 
  her to be free. The decision thus lines up with the local French council. At 
  this point Gratian himself concludes that error as to either person or status 
  leaves the person who was deceived free to leave the deceiver. Slave status 
  remains a status of importance in Christian law. 
  
  Chapter seven goes on to deal with a desperate attempt to escape marriage: a 
  married man enslaves himself to another man and contends that his marriage is 
  over. Not so, says the local Council of Trebur: he's still married and, 
  moreover, his wife remains a free woman. Gratian's headnote stamps the whole 
  maneuver as a fraud to annul the marriage. 
  
  Finally, chapter eight deals with the marriage of a slave to a slave. It is 
  valid, according to the second council of Chalons-sur-Saone: God has joined 
  them together; no man, even a master, may separate them. But there's a catch. 
  The master, or masters if there are two different owners, must first have 
  consented. Their consent makes the marriage legal. Only if legal, does it 
  become inviolable. If inviolable, it survives even though each of the married 
  pair must serve a separate owner. 
  
  Having examined in this detail a single case studied at Bologna in 1150, what 
  can we say of the first Catholic law school? The study 
  of law was, at least in part, the study of hypotheticals, with the power of 
  hypotheticals to select and isolate significant legal issues and the weakness 
  of hypotheticals that they lack the rich concreteness, the true mindbinding 
  complexity, of real cases. The hypotheticals were the basis for questions that 
  opened up substantial areas of law in a penetrating way. The questions also 
  turned out to be convenient pegs on which to hang a variety of authorities.
  
  
  The form paid off in the organization of authorities around a question. As the 
  form also permitted digressions, the student was given a glancing look at 
  problems and possibilities not immediately germane to the question asked. 
  Priests can marry validly, so Gregory the Great indicates. Gratian doesn't 
  pause to set a context. Believers in heresy may be in good faith. Gratian 
  doesn't stop to ask when. Bridegrooms may get so smashed at bridal feasts that 
  they don't recognize the bride in bed with them. Gratian abstains from 
  comment. Multiple wives were apparently once acceptable to God. Gratian does 
  not note the change in law and  [*1202]  morals. People who commit incest are 
  subject to enormous punishments. Gratian doesn't ask why. An attentive student 
  might be stimulated to think about the rules he knew and their alternatives 
  and the great variations the institution of marriage had known. A great deal 
  of tolerance of human frailties is apparent in Gratian, along with some 
  tolerance of heavy punishments. 
  
  The good side of the way Gratian put in authorities that were sometimes not 
  very pertinent to the question at hand was the breadth of experience 
  referenced. The bad side was the invitation to look at his book, not in terms 
  of questions asked, but in terms of the authorities collected - that is, not 
  to use the authorities as aids to answering Gratian's particular questions, 
  but to remove the authorities from this framework and to cite them on whatever 
  topic they shed light. The possibility was accentuated by the ahistorical 
  presentation. Context was not usually provided for the canons he cited only as 
  so many relevant rulings. In short, the temptation was to use Gratian as a 
  quarry, taking from the 4,000 authorities he used any building blocks you 
  wanted. 
  
  The difference is captured by the difference in the two titles by which the 
  work has been known. Gratian called it Concordia discordantium canonum, A 
  Harmony of Unharmonious Canons, - a title wonderful in its analogy with music 
  where harmony can come from dissonance, and a title forthrightly announcing 
  that the legislative enactments of the Church were not in harmony and needed 
  the work of scholars to be brought into working order. The other title was 
  Decretum, The Decree - a wooden title suggesting that Gratian set out "the 
  law" plain and simple. Over the centuries, treatment of the book as The Decree 
  became common. With such usage there was lost the living spirit of the law 
  school as it existed in Bologna in 1150. 
  
  In that school, as Question I of Case Twenty-Nine illustrates, authority was 
  subject to analysis. "Question Authority" was a favorite bumpersticker of the 
  1970's in America; it lingers on in a Berkeley nostalgic about the days of the 
  free speech movement. Questioning authority is also Gratian's method - a 
  method that discreetly and forcefully achieves this result by pitting one 
  authority against another. A free-wheeling dialogue is created. Gratian's 
  method of answering his questions is argumentative. He states reasons, makes 
  distinctions, creates categories, draws lines, poses analogies. As to 
  authority, theological principle is present, but in the background not the 
  foreground of the discussion. Roman law is used when helpful, and absolutely 
  ignored as if nonexistent when contrary to Christian law. Scripture is cited 
  as commanding a result, but Scripture is qualified when it appears to lead to 
  a result the teacher does  [*1203]  not approve. "You always can imply a 
  condition in a contract," Holmes has written n13 and you can always imply 
  conditions to the apparently apodictic announcements of the Bible. Gratian, a 
  master teacher, was a master of such implied qualifications, tempering 
  absolutes to custom. 
  
  Ecclesiastical authority is also invoked, again with freedom. A great pope 
  like Gregory is put on a par with a couple of provincial councils from France. 
  Gratian uses the authorities as chips to raise a doubt, bolster an argument, 
  pose a paradox. He does not stand in awe of them. 
  
  As important as authority is practice--that is, what Gratian appears to see as 
  so obvious, so taken for granted, that it needs no authority for support - for 
  example, the proposition that you cannot get out of a marriage because you 
  were mistaken as to the bride's chastity. The proposition is neither backed by 
  a citation nor argued for, except by classifying the error as an error of 
  quality. It is the way things are. Unarticulated, and perhaps only dimly 
  apprehended, is the sense operating in the background of the teacher's mind 
  that, if you let mistake become a major reason for dissolving a marriage, you 
  will not have many indissoluble unions. 
  
  Hence, it is not really explained in the text why errors as to person or as to 
  status prevent the bond from being indissoluble, while other errors, 
  conceivably of greater moment to the parties, do not. If a slave may marry, 
  why is a mistake as to a spouse's status as a slave different from a mistake 
  as to his wealth, his integrity, his mental capacity, or his chastity? You may 
  say that in a society where slavery exists, the mistake is of such a social 
  magnitude that the mistaken spouse deserves a break; but it's not too 
  difficult to think of other cases - say the spouse is a homosexual - where an 
  analogous argument can be made and the category of a status mistake asserted.
  
  
  Questions like these are not pursued in Gratian's text, but they are present 
  in the material presented and are invited by contemplation of it. Mistake as 
  to person as a reason for dissolution is the most interesting possibility of 
  all. On its face, mistakes as to person will only occur when marriage is 
  contracted at a distance. In my examination of decisions of the Roman Rota, I 
  found only one application of the rule. It came from French Indo-China before 
  World War I. An elderly widower, wanting to remarry, heard of a beautiful 
  young maiden up river. The widower sent his son to propose on his father's 
  behalf. The son dutifully went. The girl turned the father down. Mortified at 
  his failure in his filial mission, the son negotiated with another village 
  girl to return with him to be his  [*1204]  father's bride - only this one was 
  old and ugly. Back in his home village, the son told his father that he'd won 
  for his father the girl his father had heard about and wanted. Meanwhile the 
  son carefully kept the proposed bride under wraps in a local convent. The day 
  of the wedding she went to the church heavily veiled. The father became aware 
  of her age and ugliness only after he had given his consent to marriage before 
  the priest. Like Jacob, he was shocked and disbelieving that he'd married her. 
  On these facts, the Sacred Roman Rota held that the father had made a mistake 
  as to person. The marriage was annulled. You will note that the identity of 
  the woman was at issue, but the important facts about her were her age, looks, 
  and her qualities, not her name. n14 
  
  Given modern psychological explorations of what makes a person, mistake as to 
  person is a category that still has potential for development beyond the odd 
  case from Indo-China. It is, I suggest, a characteristic of Gratian's method 
  that his questions and his categories are open-ended and durable. 
  
  The largest social question raised by Case Twenty-Nine was the compatibility 
  of slavery with the Gospel of Jesus Christ. It is characteristic of Gratian 
  that he does not press the question to the point of saying slavery is a sin. 
  He will only go so far as to say slaves can marry, and even there he, or 
  perhaps an editor, unexpectedly added, only if their owners consent. From our 
  perspective it's a timorous exposition of the demands of Christianity, 
  especially so today when John Paul II can issue an encyclical, Evangelium 
  vitae, describing slavery as intrinsically evil. Christians of Gratian's day 
  did not regard slavery as intrinsically evil but as a customary division of 
  society, sanctioned by law, practiced by churchmen and religious orders, and 
  mitigated at least by the availability of Christian marriage. You can see in 
  Gratian's teaching at Bologna how the fundamental question of human freedom 
  for all was in front of him and how, bound by convention and custom, he failed 
  to address it. 
  
  Pondering this stupendous failure, we can, I think, draw a question for our
  Catholic law school today. Is there any realm or areas 
  that we avoid, any line of thought that we do not pursue, because to do so 
  would put us into too much conflict with the customs of the day? I ask, not 
  meaning now to propose an answer. 
  
  The overall impression of the first Catholic law school 
  is of opportunities missed, yes; of perfection not achieved, yes; but also of 
  argument,  [*1205]  reasoning, and reflection filled with vitality. Authority 
  is used to challenge authority. The teacher puts questions and gives 
  illustrations that challenge convention. The canons clash. The resolution is 
  with the school. 
  
  From documents after 1150, we learn that students organized the school; 
  masters were adventurers who offered their teaching to those who would pay 
  them. n15 The Registry of Bologna has a record of oaths given by masters not 
  to teach in another city. n16 There were no admission requirements, no 
  examinations, and no dean. The school did not consist in any set of buildings 
  we know of. The only information on how teachers and students lodged is a 
  decree of Pope Clement IV in 1189 excommunicating students or masters who bid 
  up the rent of a building already occupied by students. n17 The students and 
  the masters were typically treated as a unit; so a decree of the Emperor 
  Frederick Barbarossa in 1158 had recognized them. n18 
  
  The school made canon law the equal, if not the superior, of the greatest 
  legal system extant, the Roman, borrowing from its forerunner judiciously. The 
  school trained men who could be lawyers, judges, and administrators in the 
  Church from Dublin to Cracow. The school educated teachers for other 
  universities; the men who taught canon law at Oxford in the 1190's relied on 
  Gratian. n19 The school staffed the Roman curia and on a number of occasions 
  provided a pope with his education. The school made possible a system of law 
  binding Europe together. When, about a century after Gratian had first 
  composed his work, Pope Gregory IX made a new, up-to-date collection of papal 
  decrees, edited as he said to avoid prolixity, duplication, and outright 
  contradictions, he appropriately sent the collection to his "beloved sons, the 
  doctors and students" of the law school at Bologna. n20
