Monks' Rules (Author: Columbanus Hibernus)

Rule 24

24

But if any layman has eaten or drunk beside the temples, if he did it through ignorance, let him undertake forthwith never to do it again, and let him do penance forty days on bread and water. But if he did it in derision, that is, after the priest has declared to him that this was sacrilege, and if then he communicated at the table of demons, if it was only through the vice of greed that he did or repeated it, let him do penance for a hundred and twenty days on bread and water; but if he did it in worship of the demons or in honour of idols, let him do penance for three years.
