Quotes from the Saints
The Four Hundred Chapters on Love:
318. If "love is patient and kind," how can the person who is fainthearted in the troubles that befall him and who consequently deals wickedly with those who offend him, cutting himself away from love for them, help but fall away from the purpose of divine Providence?
319. Be on guard lest the vice that separates you from your brother be not found in your brother but in you; and hasten to be reconciled to him, lest you fall away from the commandment of love.
322. A temptation came upon you from your brother, and the hurt led you to hate. Do not be overcome with hate but overcome hate with love. You will prevail in this way: Pray for him sincerely to God, accept his apology, or else come up with an apology for him yourself, think of yourself as the cause of the temptation, and be patient until the cloud has passed by.
St. Maximus the Confessor
