from sin, and as by a kind of rein act as a check, and make penitents more cautious and vigilant in the future; they also remove the remnants of sin, and destroy vicious habits acquired by living evilly through acts contrary to virtue. Neither was there ever in the Church of God any way considered more secure for warding off impending punishment by the Lord than that men perform these works of penance [Matt. 3:28; 4:17; 11:21 etc.] with true sorrow of soul. Add to this that, while we suffer by making satisfaction for our sins, we are made conformable to Christ Jesus, "who made satisfaction for our sins" [Rom. 5:10; I John 2:1 f.], from whom is all our sufficiency [II Cor. 3:5], having also a most certain pledge from Him that "if we suffer with Him, we shall also be glorified" [cf. Rom. 8:17]. Neither is this satisfaction which we discharge for our sins so much our own as it is through Jesus Christ; for we who can do nothing of ourselves, as if of ourselves, with the cooperation "of Him who" comforts us, "we can do all things." Thus man has not wherein to glory; but all "our glorying" [cf. I Cor. 31; II Cor. 10:17; Gal. 6:14] is in Christ, "in whom we live, in whom we move" [cf. Acts 17:28], in whom we make satisfaction, "bringing forth fruits worthy of penance" [Luke 3:8] which have their efficacy from Him, by Him are offered to the Father, and through Him are accepted by the Father [can. 13 f.].

905. The priests of the Lord ought, therefore, so far as the spirit and prudence suggest, to enjoin salutary and suitable satisfactions, in keeping with the nature of the crimes and the ability of the penitents, lest, if they should connive at sins and deal too leniently with penitents, by the imposition of certain very light works for grave offenses, they might become participators in the crimes of others [cf. I Tim. 5:22]. Moreover, let them keep before their eyes that the satisfaction which they impose be not only for the safeguarding of a new life and a remedy against infirmity, but also for the atonement and chastisement of past sins; for the ancient Fathers both believe and teach that the keys of the priests were bestowed not only to loose, but also to bind [cf. Matt. 16:19; John 20:23; can. 15]. Nor did they therefore think that the sacrament of penance is a tribunal of wrath or of punishments; as no Catholic ever understood that from our satisfactions of this kind the nature of the merit and satisfaction of our Lord Jesus Christ is either obscured or in any way diminished; when the Innovators wish to observe this, they teach that the best penance is a new life, in order to take away all force and practice of satisfaction [can. 13].

906. It teaches furthermore that so great is the liberality of the divine munificence that not only by punishments voluntarily undertaken by us
