Commentary on Proverbs

Cyril of Jerusalem (313–386)

Someone will say, "What, then, is sin? Is it an animal? An angel? A demon? What is this which infects us?" Rest assured it is not an enemy attacking from without but an evil springing up within you. "Let your eyes look straight ahead," and there exists no evil desire. If you do not steal the property of others, robbery is at an end. Be mindful of the judgment and neither fornication nor adultery nor murder nor any wickedness will prevail over you. It is when you forget God that you begin to entertain evil thoughts and commit wicked deeds.

What does it profit a man to be an expert theologian if he is a shameless fornicator; or to be nobly temperate but an impious blasphemer? The knowledge of doctrines is a precious possession. There is need of a vigilant soul, since many there are who would deceive you by philosophy and vain deceit. The Greeks, indeed, by their smooth tongue lead men astray, for honey drops from the lips of a harlot.
