we, having done as it were an insult and a despite unto the Holy Ghost,[1] should fall into more grievous sins, treasuring up torath against the day of wrath[2] For, without doubt, these satisfactory punishments greatly recall from sin, and restrain as it were with a bridle, and make penitents more cautious and watchful for the future; they also furnish remedies for the remains of sin, and, by opposite acts of the virtues, they remove the vicious habits acquired by evil living. Neither indeed was there any way ever in the Church of God accounted surer to turn away the punishment impending at the hands of the Lord, than that men should, with true sorrow of mind, frequently practise these works of penitence.

But let them have before their eyes, that the satisfaction which they impose be not only unto the presentation of a new life, and a medicine for infirmity, but also unto the avenging and punishing of past sins. For likewise, the
