FIFTH ARTICLE: WHETHER THE PRIESTHOOD OF CHRIST ENDURES FOREVER

Reply. The answer is in the affirmative, for the Psalmist says: "Thou art a priest forever."[1563] Likewise St. Paul declares: "[Christ is] always living to make intercession for us."[1564]

Nevertheless the difficulty is that the priesthood does not endure unless there is sacrifice in the strict sense, or a visible sacrifice, and this will cease after the celebration of the last Mass at the end of the world; for in heaven the blessed see God face to face, and no more need sensible signs.

Therefore St. Thomas answers the question of this article more precisely by saying that the priesthood of Christ is said to be eternal, not because of the sacrifice that is offered, but because of its consummation, namely, because of the perpetual union of men redeemed with God clearly seen, for this is the eternal fruit of the Savior's sacrifice.

Wherefore St. Paul says: "But Christ, being come a high priest of the good things to come... by His own blood entered once into the holies, having obtained eternal redemption."[1565] Hence, after the celebration of the last Mass there will be no more sacrifice in the strict sense, nor reparation, nor prayer of petition; but there will always be the cultus of adoration and thanksgiving.[1566]

Hence Christ's priesthood is said to be eternal: (1) because its effect is the eternal salvation of men, (2) because He had no successor in this respect; (3) because He continually intercedes for us and will offer sacrifice by His ministers until the end of time; (4) because He is anointed as High Priest.

Several Thomists, such as Billuart, say that Christ's priesthood is said to be eternal because of His imperishable anointing, which is nothing else but the hypostatic union itself. If there were in heaven a sacrifice in the strict sense, then it would be a more exalted sacrifice than the sacrifice on the cross, which would not be subordinated to this latter sacrifice, but would be coordinated with it also as more exalted, and therefore the words of Christ dying on the cross, "it is consummated,"[1567] would be meaningless. On the contrary, the sacrifice of the Last Supper is directed to the sacrifice on the cross, and the sacrifice of the Mass is subordinated to the sacrifice of the cross, of which it is the application.

First doubt. What formally constitutes Christ's priesthood?[1568]

It is a disputed question among Thomists. The Salmanticenses and certain other theologians maintain that the grace of headship is what constitutes Christ's priesthood so far as this grace presupposes or connotes the grace of union. Thus Christ would be a priest by the same created habitual grace by which He is the head of the Church.

Several other Thomist theologians, such as Gonet and Hugon, are of the opinion, which is now becoming more generally admitted, that the substantial grace of union is what formally constitutes Christ's priesthood, whereby Christ as man is primarily holy by a holiness that is not only innate, but also substantial and uncreated. By this same grace Christ is holy and the sanctifier. Hence Pius XI says in one of his sacred discourses: "It is solely because it is the Homoousion of Nicaea who became incarnate... who gives Himself lavishly, inexhaustible and infinite in Jesus Christ, what the theologians call substantial victim, which consecrated Him a priest."[1569]

Scriptural proof. Christ as man is a priest inasmuch as He is anointed by God.[1570] But His primary anointing is by the grace of union. Therefore Christ is a priest by the grace of union.

Theological proof. Christ is a priest who must offer sacrifice that is of infinite value for the redemption of men. But it was only by the grace of union that His sacrifice was of infinite value; for the offering of Himself is a theandric act.

It is not enough for Christ to be the head of the human nature, for Adam was the head of the human nature raised to the supernatural order, and yet he was incapable of offering a sacrifice of infinite value.

It does not suffice to say with the Salmanticenses that what formally constitutes Christ's priesthood is habitual grace inasmuch as it connotes the grace of union, because Christ's priesthood, in what formally constitutes it as such, must be capable of offering a sacrifice that is of intrinsically infinite value; and this formally depends on the grace of union.

This seems to be the opinion of St. Thomas; for, speaking about Christ's human nature, he says: "It acquired then the actual holiness of a victim, [on the cross] from the charity it had from the beginning and from the grace of union sanctifying it absolutely."[1571] Likewise it is evident from another text of St. Thomas that Christ was predestined to natural divine sonship before He was predestined to glory and habitual grace; for it was only because Christ had to be the Son of God that He was predestined to the highest degree of glory.[1572]

Also, in the opinion of St. Thomas it is especially by the grace of union that Christ is the mediator.[1573] This opinion is also admitted by Bossuet.[1574]

Second doubt. Which title is greater in Christ, Savior or Priest forever?

Reply. Savior is the greater title, for the name "Jesus" signifies Savior. Hence the title generally used in the treatise on the Word incarnate and the Redeemer is, as in the Theological Summa of St. Thomas, the Savior, in preference to Christ the priest.

Moreover, the Savior must be a priest capable of offering a sacrifice of infinite value. But not every priest is strictly speaking a savior. The idea of savior includes more than the idea of priest.

Finally, the principal act of a priest is the act that belongs to the virtue of religion, namely, to offer sacrifice for the people; whereas the principal act of the Savior is the act of a higher virtue, namely, of charity, which commands the virtue of religion. Thus the principal act of Christ the Savior is the act of love, whereby on the cross He showed His supreme love for His Father and for souls to be saved.
