Monks' Rules (Author: Columbanus Hibernus)

Rule 12

12

If any has lost the sacrifice, let him do penance for a year. If through drunkenness or greed he has vomited it up and cast it carelessly aside, let him do penance a hundred and twenty days on bread and water; but if through ill health, let him do penance seven days.

But these provisions are made for clerics and monks collectively; now for laymen.
