On Fugitives (157-159)

Also the person who loves virtue seeks a goat by reason of his sins, but does not find one; for, already, as the sacred scripture tells us, "it has been burnt." [*] Now we must consider what is intimated under this figurative expression—how never to do any thing wrong is the peculiar attribute of God; and to repent is the part of a wise man. But this is very difficult and very hard to attain to.

Accordingly the scripture says that "Moses sought and sought again" a reason for repentance for his sins in mortal life; for he was very anxious to find a soul which was stripped of sin, and coming forward naked of all offence without shame. But nevertheless he did not find one, the flame, I mean by this the very quickly moving irrational desire, rushing inwards and devouring the whole soul.

For what is smaller in numbers is usually overpowered by what is more numerous, and what is slower by what is more speedy, and what is to come hereafter by what is present. Now what is contracted in quantity, and slow, and future, is repentance; what is numerous, and swift, and continuous in human life is, iniquity. Very naturally, therefore, when any one falls into error, he says that he is unable to eat of what is offered by reason of his sins, so that his conscience will not permit him to be nourished by repentance; on which account it is said in the scripture, "Moses heard, and it pleased him."
