If forgers and malefactors are put to death by the secular power, there is much more reason for excommunicating and even putting to death one convicted of heresy.

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.

Now this relaxation of the mind from work consists on playful words or deeds. Therefore it becomes a wise and virtuous man to have recourse to such things at times.

One day when Thomas Aquinas was preaching to the local populace on the love of God, he saw an old woman listening attentively to his every word. And inspired by her eagerness to learn more about her God whom she loved so dearly, he said to the people: It is better to be this unlearned woman, loving God with all her heart, than the most learned theologian lacking love.

Beware of the person of one book.

Reason in man is rather like God in the world.

There is nothing in your mind which wasn't experienced before hand.
