Canon IV
p. 364 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.
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.
