Most men seem to live according to sense rather than reason.

Sloth is sluggishness of the mind which neglects to begin good...it is evil in its effect, if it so oppresses man as to draw him away entirely from good deeds.

To pretend angels do not exist because they are invisible is to believe we never sleep because we don't see ourselves sleeping.

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.

By nature all men are equal in liberty, but not in other endowments.

Eternity is called whole, not because it has parts, but because it is lacking in nothing.

Unbelief is the greatest of sins.
