- Piety is, principally, revering God with filial affection, paying worship and duty to God, paying due duty to all men on account of their relationship to God, and honoring the saints and not contradicting Scripture. The Latin word pietas denotes the reverence that we give to our father and to our country; since God is the Father of all, the worship of God is also called piety (I/II.68.4; II/II.121.1).
