Ex Malo Bounum (good out of evil).
I believe in order to understand
The confession of evil works is the first beginning of good works.
Charity is the root of all good works.
Humility is the foundation of all the other virtues hence, in the soul in which this virtue does not exist there cannot be any other virtue except in mere appearance.
Heaven forbid that we should believe in such a way as not to accept or seek reasons, since we could not even believe if we did not possess rational souls.
