Augustine of Hippo, on Matt 5:43

“You have heard that it hath been said, Thou shalt love thy neighbor, and hate thy enemy.”

“(Serm. in Mont. i. 23.) After that rule we must here understand of which John speaks, He gave them power to be made the sons of God. One is His Son by nature; we are made sons by the power which we have received; that is, so far as we fulfil those things that we are commanded. So He says not, Do these things because ye are sons; but, do these things that ye may become sons. In calling us to this then, He calls us to His likeness, for He saith, He maketh His sun to rise on the righteous and the unrighteous. By the sun we may understand not this visible, but that of which it is said, To you that fear the name of the Lord, the Sun of righteousness shall arise; (Mal. 4:2.) and by the rain, the water of the doctrine of truth; for Christ was seen, and was preached to good as well as bad.”
