Canon IV. If any bishop, presbyter, deacon, sub-deacon, lector, cantor, or door-keeper has had intercourse with a woman dedicated to God, let him be deposed, as one who has corrupted a spouse of Christ, but if a layman let him be cut off. Notes. Ancient Epitome of Canon IV. A cleric coupled to a spouse of God shall be deposed.  In the case of a layman he shall be cut off. This canon is found in the Corpus Juris Canonici , Gratian’s Decretum , Pars II., Causa XXVII., Q. I., c. vj. A layman ravishing a nun, by secular law was punished by death.  Balsamon gives the reference thus:  V Cap. primi tit. iiij. lib. Basilic. or cxxiij. Novel.
