For this cause the whole company of holy prophets, apostles, martyrs, kept the word in their hearts, caring for nothing else, … When they heard the Lord say, “Forgive, and they shall be forgiven” (Luke 6:37) , then they reckoned those who wronged them as benefactors, because from them they received occasion for their own forgiveness. When again they heard, “As ye would that men should do unto you, do ye also unto them” (Matt 7:12), then they began to love good men also according to conscience. Leaving their own righteousness, and seeking the righteousness of God, they naturally found love also included in it.
