We should look upon all the faithful as one person and consider that Christ is in each one of them. We should have such love for them that we are ready to sacrifice our very lives for them. For it is incumbent upon us neither to say, nor think of any person as evil, but we must look upon everyone as good. If you see a brother afflicted with a passion, do not hate him. Hate the passion that makes war upon him. And if you see him being terrorized by the habits and desires of previous sins, have compassion on him. Maybe you too will be afflicted by temptation, since you are also made from matter that easily turns from good to evil. Love towards your brother prepares you to love God even more. The secret, therefore, of love towards God is love towards your brother. For if you don’t love your brother whom you see, how is it possible to love God whom you do not see?
For he who does not love his brother whom he has seen, cannot love God Whom he has not seen” (1 John 4:20).
