Hold firmly that our faith is identical with that of the ancients. Deny this, and you dissolve the unity of the Church.

What can be accomplished by a few principles is not effected by many. But it seems that everything we see in the world can be accounted for by other principles, supposing God did not exist. For all natural things can be reduced to one principle, which is nature, and all voluntary things can be reduced to one principle, which is human reason, or will. Therefore there is no need to suppose God's existence.

Man can sin against nature in two ways. First, when he sins against his specific rational nature, acting contrary to reason. In this sense, we can say that every sin is a sin against man's nature, because it is against man's right reason.

It is not possible to be ignorant of the end of things if we know their beginning.

The theologian considers sin mainly as an offence against God; the moral philosopher as contrary to reasonableness.

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

He who is not angry when there is just cause for anger is immoral. Why? Because anger looks to the good of justice. And if you can live amid injustice without anger, you are immoral as well as unjust.
