Prayer and Vengeance

Εἰπεν ὁ ἀββᾶς Νεῖλος· Ὅσα ἄν ποιῇς εἰς ἅμυναν ἀδελφοῦ ἠδικηκότος σε, ἄπαντα εἰς καρδίαν σοι γενήσεται ἐν καιρῷ προσευχῆς Αποφθεγματα των ἀγιων γεροντων, Παλλαδιος

Father Neilos said, Whenever you would have vengeance upon a brother who has treated you unjustly, let the time for prayer rise into your whole heart. Sayings of the Desert Fathers, Palladius of Galatia
