Augustine of Hippo, on 1John 4:8

“He that loveth not, knoweth not God: for God is charity.”

“Now see that to act against love is to act against God. Let no man say, "I sin against man when I do not love my brother, (mark it!) and sin against man is a thing to be taken easily; only let me not sin against God. How sinnest thou not against God, when thou sinnest against love? "Love is God." Do "we" say this? If we said, "Love is God" haply some one of you might be offended and say, What hath he said? What meant he to say, that "Love is God"? God "gave" love, as a gift God bestowed love. "Love is of God: Love Is God." Look, here have ye, brethren, the Scriptures of God: this epistle is canonical; throughout all nations it is recited, it is held by the authority of the whole earth, it hath edified the whole earth. Thou art here told by the Spirit of God, "Love is God." Now if thou dare, go against God, and refuse to love thy brother!”
