Virtue And Memory

Ποιήσας ἀρετὴν, μνήσθητι τοῦ εἰρηκότος, ὅτι Χωρὶς ἐμοῦ οὐ δύνασθε ποιεῖν οὐδέν. Ἅγιος Μάρκος ὁ Ἐρημίτης, Περὶ Νόμου Πνευματικοῦ  Source: Migne PG 65 911

Having performed a virtuous deed, be mindful of Him who said, 'Without me you can do nothing.' 1 Saint Mark The Ascetic, from On The Spiritual Law. 1 Jn 15.5
