WHETHER THE JUSTIFICATION OF SINNERS TAKES PLACE I N AN INSTANT OR SUCCESSIVELY
State of the question. It seems not to be instantaneous, since: 1. it requires an act of free will which entails previous deliberation; 2. it requires two acts, the love of God and the hatred of sin, which do not seem to be simultaneous; 3. habitual grace itself is susceptible of greater or less measure, and therefore is not received in an instant, but little by little according to its various degrees; 4. the movement of free will concurring toward justification is meritorious; therefore it cannot take place until after the infusion of grace, which is the principle of merit; 5. the same instant cannot be at once the first instant of the life of grace and the last instant of the state of sin, since these two opposites cannot coexist; but between two instants there must be an intermediate time; otherwise they would be identical.
The conclusion is, nevertheless, that the justification of sinners is effected by God instantaneously, at least so far as it signifies the infusion of habitual grace and the remission of sins, although the previous dispositions by which the sinner is prepared are ordinarily produced successively. However, these dispositions, as explained in the reply to the first objection, are the path to justification, but not the real substance of justification.
Proof from Scripture, according to which the Holy Ghost comes into the souls of men suddenly: “And suddenly there came a sound from heaven, as of a mighty wind coming” (Acts 2:2).
Nevertheless the Council of Trent (Sess. VI, chaps. 5 and 6) refers not only to the infusion of grace, but also to the antecedent dispositions by which the sinner is prepared, and, in this sense, justification is ordinarily effected successively, as St. Thomas himself here declares in the body of the article, in the answer to the first objection, in the preceding article 5 ad 3, and in q. 112, a. 2 ad I and 2. His teaching may be summarized as follows: Ordinarily justification including also the preceding dispositions is produced successively, for it is only under extraordinary circumstances that God sometimes bestows at the same moment of time the complete disposition and the infusion of grace, as in miraculous conversions which are utterly instantaneous, even in regard to their preparation; cf. a. 10.
Theological proof. A form is impressed upon a previously disposed subject in an instant when the agent does not require time to overcome the resistance of the subject. But justification is the impressing of habitual grace upon a previously disposed subject by God who requires no time. Therefore justification, inasmuch as it is the infusion of grace, is effected in an instant.
We are here supposing the disposition to be primary in time, not final, since justification is understood as signifying only the infusion of grace, and God almighty requires no other disposition than that which He produces and which He can also effect at the very instant when He produces grace itself, as He did in St. Paul, or gradually and successively; but this does not pertain to justification taken in sense of the infusion of grace. What does pertain to it, as we shall see in the following article, is the final disposition through an act of living faith and contrition at the very instant of justification. Therefore justification, taken in this sense, is effected in an instant.
The major is verifiable even in the natural order, inasmuch as, once the disposition for the substantial form is present in the matter, this form, of which the specific difference is indivisible, is produced in an instant; for example, an animal either is a lion; and again, transparency which is predisposed can be suddenly illuminated.
The minor is clear with reference to the infusion of grace in its precise acceptation. Indeed God sometimes produces in an instant, under extraordinary circumstances, the preliminary dispositions for grace, since acts of free will can be made instantaneously.
Confirmation. (De veritate, q. 8, a. 9.) When there is no mean between the extremes of a change, just as there is no mean in the substantial change between being and nonbeing (for example, between the being of form of a lion and not being), then the transition is made instantaneously. But between the extremes involved in justification, habitual grace on the one hand and deprivation of habitual grace on the other, there can be no mean; for man either possesses habitual grace or he does not; if he does, even in the least degree, he is already justified. Therefore.
Further confirmation is found in the refutation of the objections.
Reply to first objection. The deliberation which precedes by a priority of time is the way to justification but not the substance of justification, for which there is required the final, instantaneous consent of the deliberation to detest sin and be united to God.
Reply to the second objection. These two acts of hatred for sin and love and love of God can be simultaneous inasmuch as one is ordained to the other, for man detests sin for the reason that it is against God to whom he wishes to adhere.
Reply to the third objection. Some forms can be received to a greater or less degree, such as light or grace; yet they are produced instantaneously, for even if possessed in the least degree their essence is already present. The slightest degree of habitual grace is already a participation in the divine nature.
Reply to the fourth objection. The movements of living faith and of contrition are meritorious inasmuch as they proceed from habitual grace itself at the very moment of infusion. For grace begins to operate at once, just as fire immediately forces itself upward or produces light. This is a remarkable fact: life is infused simultaneously in first act and in second act.
Reply to fifth objection. There is no last instant in which guilt was present in the soul, but there is a last time; whereas there is a first instant in which habitual grace is present therein; however, throughout the preceding time, guilt was present. Hence the first nonexistence of guilt is the first existence of grace, which presents no contradiction. The text should be consulted in this regard. This question of the final instant is of great importance in the matter of the end of life.
It should be remarked that Cajetan (Ia, q. 64, a. I, no. 18), wishing to explain the obstinacy of a damned soul by comparison with the obstinacy of the demon, declares: “I say that the soul is settled in obstinacy by the first act which it elicits in the state of separation, and that the soul then demerits, not as in life, but as having arrived at its term; as appears from what has been said above (q. 63, a. 6, no.3) , the instant of death belongs intrinsically to the state of wayfarer.”
The Salmanticenses remark (De gratia, “de merito,” disp. I, dub. IV, no. 36): “This manner of speaking of Cajetan is generally not admitted because of the testimony of several scriptural texts according to when men can merit or lose merit before death but not in death.” Hence the same thing should be said of the state of wayfarer as has been said here of the state of sin: there is not the last instant of the life of the wayfarer, but the last moment of time; on the other hand, there is the first instant of life of the separated soul; and throughout the preceding time, infinitely divisible, the life of the wayfarer ex-isted.
Hence the first nonexistence of the wayfarer’s state is the first existence of the state of separated soul; and, as it seems, merit is then no longer possible, but only immediately before, since it is man who must merit and not a separated soul, for his body is given to him that he may tend toward his end, and after separation from the body his choice is rendered permanent. Thus is confirmed by revelation the Aristotelian thesis of the soul as the form of the body.
This problem is extremely difficult; cf. St. Thomas, Contra Gentes, Bk. IV, chaps. 92, 93, and the Commentary of Francis Silvester (Ferrariensis) who does not follow Cajetan. We have dealt with this question in the treatise De Deo creatore, pp. 408-12.
