Chapter 16 — Part I — Penitence

Section 356. Q. What is the epitimia? A. The word means punishment. See 2 Cor. ii. 6. Under this name are prescribed to the penitent, according as may be requisite, divers particular exercises of piety, and divers abstinences or privations, serving to efface the unrighteousness of sin, and to subdue sinful habit; as, for instance, fasting beyond what is prescribed for all, or for grievous sins suspension from the holy Communion for a given time.
