…St Isaac says, “Do not hate the sinner; we are all sinners and deserve condemnation. If you are moved for God’s sake, weep over him. Why should you hate him? Hate his sins and pray for him and you will resemble Christ Who was not angry with sinners but prayed for them. Do you not see how He wept over Jerusalem? But in many cases we become a laughingstock for the devil. Why should we hate those who are mocked like ourselves by the very devil who mocks us? Why, O man, do you hate the sinner? Because he is not so righteous as you are. But where is your righteousness when you have no love? And if you have love, why do you not weep for him instead of persecuting him? Some people, thinking that they have sound judgment in regard to the deeds of sinners, get angry with them; they act like this out of ignorance.”
Self-opinion, presumption, or conceit is a great calamity. Refusal of humility is a great calamity.
