What noble thing have you produced by your pursuit of philosophy? Who of your most eminent men has been free from vain boasting?

On this account the nature of the demons has no place for repentance; for they are the reflection of matter and of wickedness. But matter desired to exercise lordship over the soul; and according to their free-will these gave laws of death to men; but men, after the loss of immortality, have conquered death by submitting to death in faith; and by repentance a call has been given to them, according to the word which says, "Since they were made a little lower than the angels."
