Sankt Gallen, Stiftsbibliothek 673, fol. 145
<Gratian> Many authorities prohibit that regular canons may transfer.
Whence in a council <of Autun 1077 A.D.?> convened under the Seventh Gregory it is stated:
No abbot or monk may dare receive someone to become a monk wearing the monastic habit and calling him back from the intention of a canonical profession as long as they can find churches of their order in which they live canonically and serving God and in which they can save their souls. If abbots and monks rashly dare to do this they will be condemned by the bond of anathema.
