“Do not regard the feelings of a person who speaks to you about his neighbor disparagingly, but rather say to him: “Stop, brother! I fall into graver sins every day, so how can I criticize him?” In this way you will achieve two things: you will heal yourself and your neighbor with one plaster. This is one of the shortest ways to the forgiveness of sins; I mean, not to judge. ‘Judge not, and ye shall not be judged.’ (Luke 6:37)”
-St. John Climacus
“If we have true love with sympathy and patient labor, we shall not go about scrutinizing our neighbor’s shortcomings. As it is said, “Charity shall cover the multitude of sins” (1 Peter 4:8), and again, “Love thinketh no evil… hides everything, etc.”(1 Cor.13:5,6) As I said, if we have true love, that very love should screen anything of this kind, as did the saints when they saw the shortcomings of men.Were they blind? Not at all! But they simply would not let their eyes dwell on sins.”
-Saint Dorotheos of Gaza
“My children, avoid criticism — a very great sin. God is grieved whenever we criticize and loathe people. Let us concern ourselves only with our own faults — for these let us feel pain; let us criticize ourselves and then we will find mercy and grace from God.”
-Elder Ephraim of Philotheou Mount Athos
