To seek the greatest good is to live well, and to live well is nothing other than to love God with the whole heart, the whole soul, and the whole mind: It is therefore obvious that this love must be kept whole and uncorrupt, that is temperance; it should not be overcome with difficulties, that is fortitude, it must not be subservient to anything else, that is justice; it must discriminate among things so as not to be deceived by falsity or fraud, that is prudence.

The same divine authority that forbids the killing of a human being establishes certain exceptions, as when God authorizes killing by a general law or when He gives an explicit commission to an individual for a limited time.

The mind commands the body, and it obeys forthwith; the mind commands itself, and is resisted. The mind commands the hand to be moved, and such readiness is there that the command is scarce to be distinguished from the obedience. Yet the mind is mind, and the hand is body. The mind commands the mind to will, and yet, though it be itself, it obeyeth not. Whence this monstrous thing? and why is it?

Six is a number perfect in itself, and not because God created the world in six days; rather the contrary is true. God created the world in six days because this number is perfect, and it would remain perfect, even if the work of the six days did not exist.

Love and do what you want. If you stop talking, you will stop talking with love; if you shout, you will shout with love; if you correct, you will correct with love.

People travel to marvel at the mountains, seas, rivers and stars and they pass right by themselves without astonishment.

The measure of love is to love without measuring.
