Augustine of Hippo

The renewal of humankind, begun in the sacred bath of baptism, proceeds gradually and is accomplished more quickly in some individuals and more slowly in others. But many are in progress toward the new life if we consider the matter carefully and without prejudice. As the apostle says: "Even though our outer man is decaying, yet our inner man is being renewed day by day." He says that the inner man is renewed day by day in order that he may become perfect, but you would have him begin with perfection. Would that you really did desire this! But you seek to lead the unwary astray rather than to uplift the weak.
