Nobody should ever doubt that in the washing of rebirth (Titus 3:5) absolutely all sins, from the least to the greatest, are altogether forgiven. - Augustine of Hippo

Whoever, then, thinks that he understands the Holy Scriptures, or any part of them, but puts such an interpretation upon them as does not tend to build up this twofold love of God and our neighbor, does not yet understand them as he ought.

The mind commands the body, and obedience is instant; the mind commands itself and meets resistance. The mind tells the hand to move, and all goes so smoothly that it is hard to distinguish the command from its execution. Yet the mind is the mind, and the hand is a body. The mind tells the mind to will; one is the same as the other, and yet it does not do what it is told.

"There is no sin unless through a man's own will, and hence the reward when we do right things also of our own will."

(Against Fortunatus)
