Chapter 25 — Part III — On Love (Introduction)

Section 493. Q. Has not Jesus Christ said something of this? A. When asked, Which is the great commandment in the law? he replied: Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it: Thou shalt love thy neighbor as thyself. On these two commandments hang all the law and the prophets. Matt. xxii. 36-40.
