ACC ~ John 13 v17
PRACTICE VIRTUE
CYRIL OF ALEXANDRIA: It is not the knowledge of virtue but rather the practice of it that may be appropriately called worthy of both love and enthusiasm. … Whenever actions go hand in hand with knowledge, then assuredly there is no small gain. But when either is lacking, the other will be seriously crippled. And it is written, even faith apart from works is dead. [1] Although the knowledge of God who is one even in nature, and the confession of God in guilelessness and truth is all included in faith, even this is dead if it is not accompanied by the bright light that proceeds from works. Surely, therefore, it is utterly profitless merely to know what is good and yet have no desire to practice it at once. COMMENTARY ON THE GOSPEL OF JOHN 9. [2]
