“You have heard that it was said, ‘Love your neighbor and hate your enemy.’ But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect. Matthew 5:43-48
“A brother said to a hermit, “If I see a monk about whom I have heard that he is guilty of sin, I cannot make myself invite him into my cell. But if I see a good monk, I bring him in gladly.” The hermit said, “If you do good to a good brother, it is nothing to him, but to the other give double charity, for he is sick.”
