Brothers, do not slander one another. Anyone who speaks against his brother or judges him speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it.
"You have heard that it was said to the people long ago, 'Do not murder, and anyone who murders will be subject to judgment.' But I tell you that anyone who is angry with his brother will be subject to judgment. Again, anyone who says to his brother, 'Raca,' is answerable to the Sanhedrin. But anyone who says, 'You fool!' will be in danger of the fire of hell.
"Therefore, if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there in front of the altar. First go and be reconciled to your brother; then come and offer your gift."
"Do not waste time bothering whether you "love" your neighbor; act as if you do. As soon as we do this we find one of the great secrets. When you are behaving as if you love someone you will presently come to love him."
C. S. Lewis
A man is called selfish not for pursuing his own good, but for neglecting his neighbor's.
Richard Whately
"You are told to love your neighbor as yourself. How do you love yourself? When I look into my own mind, I find that I do not love myself by thinking myself a dear old chap or having affectionate feelings. I do not think that I love myself because I am particularly good, but just because I am myself and quite apart from my character. I might detest something which I have done. Nevertheless, I do not cease to love myself. In other words, that definite distinction that Christians make between hating sin and loving the sinner is one that you have been making in your own case since you were born."
C. S. Lewis
How seldom we weigh our neighbor in the same balance with ourselves.
Thomas à Kempis
A man prone to suspect evil is mostly looking in his neighbor for what he sees in himself.
