Chap. 12. Rash Presumption of Predestination is to be Avoided

805. No one moreover, so long as he lives in this mortal state, ought so far to presume concerning the secret mystery of divine predestination, as to decide for certain that he is assuredly in the number of the predestined [can. 15], as if it were true that he who is justified either cannot sin any more [can. 23], or if he shall have sinned, that he ought to promise himself an assured reformation. For except by special revelation, it cannot be known whom God has chosen for Himself [can. 16].

Chap. 13. The Gift of Perseverance

806. So also as regards the gift of perseverance [can. 16] of which it is written: He that "shall persevere to the end, he shall be saved" [Matt. 10:22; 24:13] (which gift cannot be obtained from anyone except from Him, "who is able to make him, who stands, stand" [Rom. 14:4], that he may stand perseveringly, and to raise him, who falls), let no one promise himself anything as certain with absolute certitude, although all ought to place and repose a very firm hope in God's help. For God, unless men be wanting in His grace, as He has begun a good work, so will He perfect it, "working to will and to accomplish" [Phil. 2:13; can. 22].¹ Nevertheless, let those "who think themselves to stand, take heed lest they fall" [I Cor. 10:12], and "with fear and trembling work out their salvation" [Phil. 2:12] in labors, in watchings, in almsdeeds, in prayers and oblations, in fastings and chastity [cf. II Cor. 6:3 ff.]. For they ought to fear, knowing that they are born again "unto the hope of glory" [cf. I Rom. Pet. 1:3], and not as yet unto glory in the combat that yet remains with the flesh, with the world, with the devil, in which they cannot be victors, unless with God's grace they obey the Apostle saying: "We are debtors, not to the flesh, to live according to the flesh. For if you live according to the flesh, you shall die. But if by the spirit you mortify the deeds of the flesh, you shall live" [Rom. 8:12 ff.].

Chap. 14. The Fallen and Their Restoration

807. Those who by sin have fallen away from the received grace of justification, will again be able to be justified [can. 29] when, roused by God through the sacrament of penance, they by the merit of Christ shall have attended to the recovery of the grace lost. For this manner of justification is the reparation of one fallen, which the holy Fathers² have aptly called
