FIFTH ARTICLE: WHETHER THE GRACE OF CHRIST AS HEAD OF CHURCH IS THE SAME AS HIS HABITUAL GRACE, INASMUCH AS HE IS MAN

State of the question. Is Christ's grace as head of the Church really distinct from His personal habitual grace, or are the two graces identical?

It seems that they are not the same, for the following reasons.

1) The actual or personal sin of Adam differs from original sin which He transmitted to posterity. Therefore the personal grace of Christ the new Adam is not the same as His grace of headship.

2) These graces are distinct inasmuch as they are ordained to different acts, for Christ's personal grace is ordained for His sanctification, whereas His capital grace is for the sanctification of others.

3) Theologians usually distinguish between three kinds of graces in Christ: the grace of union, the individual grace of the man, and the capital grace.

Conclusion. Christ's personal habitual grace and His capital grace are essentially the same, though there is a mental distinction between them.

Very many theologians accept this conclusion, though Vasquez and certain others teach that Christ's capital grace and His grace of union are really the same.

Scriptural proof. The Evangelist says: "of His fullness we all have received."[1083] Hence Christ is our head inasmuch as He had the fullness of personal habitual grace. Hence there is no real distinction between Christ's habitual grace and His capital grace; at least, the text quoted above implies that these two graces are really identical.

Theological proof. There is no difference between the act whereby anything is in act and whereby it acts, and the agent must be nobler than the patient. But Christ as man is constituted supernaturally in act by the personal habitual grace which He received in the highest degree. Therefore Christ as man bestowed this same grace on others, namely, on those members whose head He is.

The major is evident, for it is founded on the principle that everything acts inasmuch as it is a being in act. Thus what is hot heats according to the heat whereby it is hot. For the agent acts, inasmuch as it determines, and the manner of its determination is in accordance with its own determination.

The minor was explained above: for personal habitual grace intrinsically and physically informs Christ, as man. Thus this grace is the operative principle whereby He radically operates supernaturally, performing acts that are infinitely meritorious and satisfactory. The principium quo of these operations is habitual grace as it connotes the grace of union, or as it connotes the principium quod, or the person of the Word, from whom these works derive their infinite value.[1084]

Therefore this same habitual grace is called capital, inasmuch as by it Christ can bestow on the members of the Church grace and justification, that is, by exerting a moral influence on them by means of His infinitely meritorious and satisfactory works. It is precisely this influence that constitutes Him their head, although He also exerts a physically instrumental influence on them. Christ, the head of the faithful of the Old Testament, could not exert a physically instrumental influence on them, but only a moral influence by His merit and satisfaction, since they lived before His coming.

St. Thomas often speaks of this physically instrumental causality of Christ's human nature, inasmuch as it is the instrument united with the divine nature, whereas the sacraments are separate instruments.[1085] As one who blows a trumpet emits the sound by this instrument, so God can cause grace by Christ's human nature; so also our soul makes use of vocal chords as the instrument of speech. Moreover, it must be observed that, although Christ's body, inasmuch as it is in heaven as in a place, is locally distant from ours, the higher part of Christ's soul and of our soul are not of themselves localized, nor is Christ's mind locally distant from our mind, which is influenced by His mind, inasmuch as it is the instrument of His divine nature.[1086]

As regards moral causality by way of merit, it is not necessary that the moral cause already exist for it to exert its influence, since the moral cause operates inasmuch as it is known, and can be known as coming into existence. Thus God conferred grace on the faithful of the Old Testament because of Christ's future merits.

The solution of the objections confirms the conclusion.

Reply to first objection. We must distinguish in Adam between his personal sin and original sin that had its origin in him, which is a sin of the nature, "because in him the person, by turning away from God, corrupted the nature; and by means of this corruption the sin of the first man is transmitted to posterity.... Now grace is not vouchsafed us by means of human nature, but solely by the personal action of Christ Himself. Hence we must not distinguish a twofold grace in Christ, one corresponding to the nature, the other to the person." This means, as Cajetan observes, that "grace is not communicated to us by the action of the nature, or by communicating the nature as Adam would have communicated it, not corrupted, to his children, if he had not sinned, but by Christ's personal action, by which He merited for us and of His own will bestowed grace on us."[1087]

Reply to second objection. The eminence of Christ's personal habitual grace is the reason for the justification of others.

Reply to third objection. "The personal and the capital grace agree in the essence of the habit"; they are the same habit inasmuch as their more proximate purpose is for the performance of some meritorious act. On the contrary, the direct purpose of the grace of union is not for the eliciting of a meritorious act, and it is not a habit but, as stated above, "the grace of union is the personal being that is given gratis by God to the human nature in the person of the Word."[1088]

Objection. But for Vasquez the capital grace and the grace of union are identical because, so he says, the infinite value of Christ's merits is derived from this grace of union.

Reply. That the value of Christ's merits is derived remotely from the grace of union as from the principium quod[1089] that is connotated, this I concede; that it is derived proximately as from the operative principium quo, this I deny, although charity is the immediate principle of merit. It pertains to the notion of capital grace, however, for it to be the root, instrumentally, of those merits because the head of the Church as such exerts at least a moral influence on the members by His meritorious works.

But I insist. If Christ did not have habitual grace, He would, nevertheless, still be our head; for habitual grace is not absolutely necessary so as to enable Him to elicit meritorious acts. Therefore Christ is not the head because of habitual grace.

Reply. I distinguish the antecedent: If Christ did not have habitual grace, He would still be our head because of His divine personality, this I deny, for His personality does not constitute Him the operative principle of merit; because of the transient help given by it, this I concede. But then Christ would not be the connatural operative principle of merit.

Again I insist. Grace that is ordained for the sanctification of others is not grace gratum faciens, but grace gratis data. Therefore Christ's capital grace that is ordained for our sanctification is not identical with His personal habitual grace.

Reply. I distinguish the antecedent: Grace that is primarily ordained for the sanctification of others is not gratia gratum faciens, this I concede; grace that is only secondarily so ordained is not such, this I deny. Thus the gift of wisdom is included in sanctifying grace, although its secondary purpose is for the direction of souls, which means that it is for the benefit of others. Such was Christ's habitual grace.
