When someone has a vice we should try to bombard him with rays of love and compassion so that he may be cured and freed. These things are achieved only through the grace of God. Think that this person is suffering more than you. In a cenobitic monastery when someone is at fault, we should not tell him that he is to blame. We must adopt an attitude of care, respect and prayer. We must endeavor not to do anything harmful. When we endure insults from our brother, it counts as martyrdom. And it is something we should endure with joy.
