1 Objection 1: It seems that predestination is not certain. Because on the words Hold fast that which thou hast, that no one take thy crown, Rev 3, 11), Augustine says De Corr. et Grat. 15): Another will not receive, unless this one were to lose it. Hence the crown which is the effect of predestination can be both acquired and lost. Therefore predestination cannot be certain.
1 Ad sextum sic proceditur. Videtur quod praedestinatio non sit certa. Quia super illud Apoc. III, tene quod habes, ne alius accipiat coronam tuam, dicit Augustinus, quod alius non est accepturus, nisi iste perdiderit. Potest ergo et acquiri et perdi corona, quae est praedestinationis effectus. Non est igitur praedestinatio certa.
2 Objection 2: Further, granted what is possible, nothing impossible follows. But it is possible that one predestined, for example, Peter, may sin and then be killed. But if this were so, it would follow that the effect of predestination would be thwarted. This then, is not impossible. Therefore predestination is not certain.
2 Praeterea, posito possibili, nullum sequitur impossibile. Possibile est autem aliquem praedestinatum, ut Petrum, peccare, et tunc occidi. Hoc autem posito, sequitur praedestinationis effectum frustrari. Hoc igitur non est impossibile. Non ergo est praedestinatio certa.
3 Objection 3: Further, whatever God could do in the past, He can do now. But He could have not predestined whom He hath predestined. Therefore now He is able not to predestine him. Therefore predestination is not certain.
3 Praeterea, quidquid Deus potuit, potest. Sed potuit non praedestinare quem praedestinavit. Ergo nunc potest non praedestinare. Ergo praedestinatio non est certa.
4 On the contrary, A gloss on Rm. 8, 29: Whom He foreknew, He also predestinated, says: Predestination is the foreknowledge and preparation of the benefits of God, by which whosoever are freed will most certainly be freed.
4 Sed contra est quod super illud Rom. VIII, quos praescivit, et praedestinavit etc., dicit Glossa, praedestinatio est praescientia et praeparatio beneficiorum Dei, qua certissime liberantur quicumque liberantur.
5 I answer that, Predestination most certainly and infallibly takes effect; yet it does not impose any necessity, so that, namely, its effect should take place from necessity. For it was said above Article 1), that predestination is a part of providence. But not all things subject to providence are necessary; some things happening from contingency, according to the nature of the proximate causes, which divine providence has ordained for such effects. Yet the order of providence is infallible, as was shown above Question 22, Article 4). So also the order of predestination is certain; yet free-will is not destroyed; whence the effect of predestination has its contingency. Moreover all that has been said about the divine knowledge and will Question 14, Article 13; Question 19, Article 4) must also be taken into consideration; since they do not destroy contingency in things, although they themselves are most certain and infallible.
5 Respondeo dicendum quod praedestinatio certissime et infallibiliter consequitur suum effectum, nec tamen imponit necessitatem, ut scilicet effectus eius ex necessitate proveniat. Dictum est enim supra quod praedestinatio est pars providentiae. Sed non omnia quae providentiae subduntur, necessaria sunt, sed quaedam contingenter eveniunt, secundum conditionem causarum proximarum, quas ad tales effectus divina providentia ordinavit. Et tamen providentiae ordo est infallibilis, ut supra ostensum est. Sic igitur et ordo praedestinationis est certus; et tamen libertas arbitrii non tollitur, ex qua contingenter provenit praedestinationis effectus. Ad hoc etiam consideranda sunt quae supra dicta sunt de divina scientia et de divina voluntate, quae contingentiam a rebus non tollunt, licet certissima et infallibilia sint.
6 Reply to Objection 1: The crown may be said to belong to a person in two ways; first, by God's predestination, and thus no one loses his crown: secondly, by the merit of grace; for what we merit, in a certain way is ours; and thus anyone may lose his crown by mortal sin. Another person receives that crown thus lost, inasmuch as he takes the former's place. For God does not permit some to fall, without raising others; according to Job 34, 24: He shall break in pieces many and innumerable, and make others to stand in their stead. Thus men are substituted in the place of the fallen angels; and the Gentiles in that of the Jews. He who is substituted for another in the state of grace, also receives the crown of the fallen in that in eternal life he will rejoice at the good the other has done, in which life he will rejoice at all good whether done by himself or by others.
6 Ad primum ergo dicendum quod corona dicitur esse alicuius, dupliciter. Uno modo, ex praedestinatione divina, et sic nullus coronam suam amittit. Alio modo, ex merito gratiae, quod enim meremur, quodammodo nostrum est. Et sic suam coronam aliquis amittere potest per peccatum mortale sequens. Alius autem illam coronam amissam accipit, inquantum loco eius subrogatur. Non enim permittit Deus aliquos cadere, quin alios erigat, secundum illud Iob XXXIV, conteret multos et innumerabiles, et stare faciet alios pro eis. Sic enim in locum Angelorum cadentium substituti sunt homines; et in locum Iudaeorum, gentiles. Substitutus autem in statum gratiae, etiam quantum ad hoc coronam cadentis accipit, quod de bonis quae alius fecit, in aeterna vita gaudebit, in qua unusquisque gaudebit de bonis tam a se quam ab aliis factis.
7 Reply to Objection 2: Although it is possible for one who is predestinated considered in himself to die in mortal sin; yet it is not possible, supposed, as in fact it is supposed. that he is predestinated. Whence it does not follow that predestination can fall short of its effect.
7 Ad secundum dicendum quod, licet sit possibile eum qui est praedestinatus, mori in peccato mortali, secundum se consideratum; tamen hoc est impossibile, posito prout scilicet ponitur) eum esse praedestinatum. Unde non sequitur quod praedestinatio falli possit.
8 Reply to Objection 3: Since predestination includes the divine will as stated above Article 4): and the fact that God wills any created thing is necessary on the supposition that He so wills, on account of the immutability of the divine will, but is not necessary absolutely; so the same must be said of predestination. Wherefore one ought not to say that God is able not to predestinate one whom He has predestinated, taking it in a composite sense, thought, absolutely speaking, God can predestinate or not. But in this way the certainty of predestination is not destroyed.
8 Ad tertium dicendum quod, cum praedestinatio includat divinam voluntatem, sicut supra dictum est quod Deum velle aliquid creatum est necessarium ex suppositione, propter immutabilitatem divinae voluntatis, non tamen absolute; ita dicendum est hic de praedestinatione. Unde non oportet dicere quod Deus possit non praedestinare quem praedestinavit, in sensu composito accipiendo; licet, absolute considerando, Deus possit praedestinare vel non praedestinare. Sed ex hoc non tollitur praedestinationis certitudo.
