Chapter 22 — Part II: The Sacraments — Matrimony
Section 25. Marriage Not Obligatory On All — The words increase and multiply, which were uttered by the Lord, do not impose on every individual an obligation to marry, but only declare the purpose of the institution of marriage. Now that the human race is widely diffused, not only is there no law rendering marriage obligatory, but, on the contrary, virginity is highly exalted and strongly recommended in Scripture as superior to marriage, and as a state of greater perfection and holiness. For our Lord and Saviour taught as follows: He that can take it, let him take it; and the Apostle says: Concerning virgins I have no commandment from the Lord; but I give counsel as having obtained mercy from the Lord to be faithful.
