You say that So-and-so is an evil-doer and may he burn in hell fire. But I ask you — supposing God were to give you a fair place in paradise, and you saw burning in the fire the man on whom you had wished the tortures of hell, even then would you really not feel pity for him, whoever he might be, an enemy of the Church even? Or is it that you have a heart of steel? But there is no place for steel in paradise. Paradise has need of humility and the love of Christ, which pities all men. The grace of God is not in the man who does not love his enemies.
-St. Silouan the Athonite
