c.18: Clerics may not shed blood; may not participate in ordeal

Sententiam sanguinis nullus clericus dictet aut proferat, Sed nec sanguinis vindictam exerceat aut ubi exercetur intersit. Si quis autem huiusmodi occasione statuti ecclesiis vel personis  ecclesiasticis aliquod  praesumpserit inferre dispendium, per censuram ecclesiasticam compescatur, nec quisquam clericus litteras scribat aut dictet pro vindicta sanguinis destinandas, unde in curiis principum haec solicitudo non c1ericis sed laicis committatur. Nullus quoque clericus rottariis aut balistariis aut huiusmodi viris sanguinum praeponatur, nec illam chirurgiae artem subdiaconus, diaconus ve1 sacerdos exerceant, quae ad ustionem vel incisionem inducit. nec quisquam purgationi aquae ferventis vel frigidae seu ferri candentis ritum cuiuslibct bcnedictionis aut consecrationis impendat, salvis nihilominus prohibitionibus de monomachiis sive duellis antea promulgatis. No cleric may render or dictate or carry out a punishment involving the shedding of blood or carry out a punishment involving the shedding of blood or be present when such punishment is carried out. If anyone, however, under cover of this statute, dares inflict injury on churches or ecclesiastical persons, let him be restrained by ecclesiastical censure. A cleric may not write or dictate leHers which require punishments involving the shedding of blood; in the courtS of princes this responsibility should be entrusted to laymen and nOt to clerics. Moreover no cleric may be put in.command of mercenaries or crossbowmen or suchlike men of blood; nor maya subdeacon, deacon or priest practise the art of surgery, which involves cauterizing and making incisions; nor may anyone confer a rite of blessing or consecration on a purgation by ordeal of boiling or cold water or of the red-hot iron, saving nevertheless the previously promulgated prohibitions  regarding single combats and duels. = 4 Comp. 3.19.2
