A man does not always choose what his guardian angel intends.

It is altogether unlawful to kill oneself... Wherefore suicide is contrary to the inclination of nature, and to charity whereby every man should love himself... Life is God's gift to man, and is subject to His power, Who kills and makes to live. Hence whoever takes his own life, sins against God... for it belongs to God alone to pronounce sentence of death and life.

Likewise grace and glory are referred to the same genus, since grace is nothing other than a certain first beginning of glory in us.

If a man deliberately abstains from wine to such an extent that he does serious harm to his nature, he will not be free from blame.

For loving draws us more to things than knowing does, since good is found by going to the thing, whereas the true is found when the thing comes to us.

All my words are but chaff next to the faith of a simple man.

Rarely affirm, seldom deny, always distinguish.
