And if a good tree cannot produce evil fruit, and as, according to them, Peter and Paul were sprung from the root of a good tree, how should they be deemed to have brought forth fruits so wicked? And if they should return the answer which is generally invented, that it was not Paul who persecuted, but some other person, I know not whom, who was in Paul; and that it was not Peter who uttered the denial, but some other individual in him; how should Paul say, if he had not sinned, that I am not worthy to be called an apostle, because I persecuted the Church of God? Or why did Peter weep most bitterly, if it were another than he who sinned? From which all their silly assertions will be proved to be baseless. (Book I, Chapter 8, Part 2)

Good and evil often abide together.

Evil originally meant excessive, over-reaching. Good intent can over-reach.

Wicked is derived from words meaning a small place and came to mean a wretched and forsaken place.

Good can be too narrowly focused and contained.

To be good involves cultivating a balance that is neither too big nor too small.
