Galatians 5:14

For the whole law is fulfilled in one word, even this: Thou shalt love thy neighbor as thyself.

The "law" in view here is the "law of Christ," mentioned again in Galatians 6:2. True, this was a commandment of the Law of Moses (Leviticus 19:18), but that is not the frame of reference applicable here. Christ himself had made the "first and great commandment" to be the "love of God, and love of one's neighbor" (Mark 12:29-31), nor has there ever been, from the morning of creation, the slightest relaxation of this primary obligation of all who were ever born on earth. In Romans 13:8-10, Paul outlined this principle more fully, specifying as specific components of this law of Christ such commandments as "Thou shalt not commit adultery ... nor steal ... nor kill ... nor covet, etc." There also, Paul indicated that love of the brethren is the heart condition that makes the honoring of such commandments possible for the Christian. As Huxtable said, "This passage in Romans is a lengthened paraphrase of the one before us."[15] For further exegesis on all of this, see my Commentary on Romans, Romans 13:9-10.
