Chapter 22 — Part II: The Sacraments — Matrimony

Section 2. But as, according to the same Apostle, every one hath his proper gift from God, one after this manner, and another after that; and as marriage is gifted with great and divine blessings, so much so as truly and properly to hold a place among the other Sacraments of the Catholic Church, and as its celebration was honoured by the presence of our Lord Himself, it is clear that this subject should be explained, particularly since we find that St. Paul and the Prince of the Apostles have in many places minutely described to us not only the dignity but also the duties of the married state. Filled with the Spirit of God (these Apostles) well understood the numerous and important advantages which must flow to Christian society from a knowledge, and an inviolable observance by the faithful of the sanctity of marriage; while they saw that from ignorance or disregard of (its holiness), many and serious calamities and losses must be brought upon the Church.
