Of the Priesthood of Christ

Of the Priesthood of Christ — St. Thomas Aquinas asks: Whether it is fitting that Christ should be a priest?; Whether Christ was Himself both priest and victim?; Whether the effect of Christ's priesthood is the expiation of sins?; Whether the effect of the priesthood of Christ pertained not only to others, but also to Himself?; Whether the priesthood of Christ endures for ever?; Whether the priesthood of Christ was according to the order of Melchisedech?.

We have now to consider the Priesthood of Christ; and under this head there are six points of inquiry:

Article 1: Whether it is fitting that Christ should be a priest?

It is written (Heb. 4:14): "We have [Vulg.: 'Having'] therefore a great high-priest that hath passed into the heavens, Jesus, the Son of God."

The office proper to a priest is to be a mediator between God and the people: to wit, inasmuch as He bestows Divine things on the people, wherefore "sacerdos" [priest] means a giver of sacred things [sacra dans], according to Malachi 2:7: "They shall seek the law at his," i.e. the priest's, "mouth"; and again, forasmuch as he offers up the people's prayers to God, and, in a manner, makes satisfaction to God for their sins; wherefore the Apostle says (Heb. 5:1): "Every high-priest taken from among men is ordained for men in the things that appertain to God, that he may offer up gifts and sacrifices for sins." Now this is most befitting to Christ. For through Him are gifts bestowed on men, according to 2 Pet. 1:4: "By Whom" (i.e. Christ) "He hath given us most great and precious promises, that by these you may be made partakers of the Divine Nature." Moreover, He reconciled the human race to God, according to Col. 1:19,20: "In Him" (i.e. Christ) "it hath well pleased (the Father) that all fulness should dwell, and through Him to reconcile all things unto Himself." Therefore it is most fitting that Christ should be a priest.

Article 2: Whether Christ was Himself both priest and victim?

The Apostle says (Eph. 5:2): "Christ hath loved us, and hath delivered Himself for us, an oblation and a victim [Douay: 'sacrifice'] to God for an odor of sweetness."

As Augustine says (De Civ. Dei x, 5): "Every visible sacrifice is a sacrament, that is a sacred sign, of the invisible sacrifice." Now the invisible sacrifice is that by which a man offers his spirit to God, according to Ps. 50:19: "A sacrifice to God is an afflicted spirit." Wherefore, whatever is offered to God in order to raise man's spirit to Him, may be called a sacrifice.

Now man is required to offer sacrifice for three reasons. First, for the remission of sin, by which he is turned away from God. Hence the Apostle says (Heb. 5:1) that it appertains to the priest "to offer gifts and sacrifices for sins." Secondly, that man may be preserved in a state of grace, by ever adhering to God, wherein his peace and salvation consist. Wherefore under the old Law the sacrifice of peace-offerings was offered up for the salvation of the offerers, as is prescribed in the third chapter of Leviticus. Thirdly, in order that the spirit of man be perfectly united to God: which will be most perfectly realized in glory. Hence, under the Old Law, the holocaust was offered, so called because the victim was wholly burnt, as we read in the first chapter of Leviticus.

Now these effects were conferred on us by the humanity of Christ. For, in the first place, our sins were blotted out, according to Rom. 4:25: "Who was delivered up for our sins." Secondly, through Him we received the grace of salvation, according to Heb. 5:9: "He became to all that obey Him the cause of eternal salvation." Thirdly, through Him we have acquired the perfection of glory, according to Heb. 10:19: "We have [Vulg.: 'Having'] a confidence in the entering into the Holies" (i.e. the heavenly glory) "through His Blood." Therefore Christ Himself, as man, was not only priest, but also a perfect victim, being at the same time victim for sin, victim for a peace-offering, and a holocaust.

Article 3: Whether the effect of Christ's priesthood is the expiation of sins?

The Apostle says (Heb. 9:14): "The blood of Christ, Who by the Holy Ghost offered Himself unspotted unto God, shall cleanse our conscience from dead works, to serve the living God." But dead works denote sins. Therefore the priesthood of Christ has the power to cleanse from sins.

Two things are required for the perfect cleansing from sins, corresponding to the two things comprised in sin---namely, the stain of sin and the debt of punishment. The stain of sin is, indeed, blotted out by grace, by which the sinner's heart is turned to God: whereas the debt of punishment is entirely removed by the satisfaction that man offers to God. Now the priesthood of Christ produces both these effects. For by its virtue grace is given to us, by which our hearts are turned to God, according to Rom. 3:24,25: "Being justified freely by His grace, through the redemption that is in Christ Jesus, Whom God hath proposed to be a propitiation, through faith in His blood." Moreover, He satisfied for us fully, inasmuch as "He hath borne our infirmities and carried our sorrows" (Is. 53:4). Wherefore it is clear that the priesthood of Christ has full power to expiate sins.

Article 4: Whether the effect of the priesthood of Christ pertained not only to others, but also to Himself?

We read in the acts of the Council of Ephesus [*Part III, ch. i, anath. 10]: "If anyone say that Christ offered sacrifice for Himself, and not rather for us alone (for He Who knew not sin needed no sacrifice), let him be anathema." But the priest's office consists principally in offering sacrifice. Therefore the priesthood of Christ had no effect in Himself.

As stated above (), a priest is set between God and man. Now he needs someone between himself and God, who of himself cannot approach to God; and such a one is subject to the priesthood by sharing in the effect thereof. But this cannot be said of Christ; for the Apostle says (Heb. 7:25): "Coming of Himself to God, always living to make intercession for us [Vulg.: 'He is able to save for ever them that come to God by Him; always living,' etc.]." And therefore it is not fitting for Christ to be the recipient of the effect of His priesthood, but rather to communicate it to others. For the influence of the first agent in every genus is such that it receives nothing in that genus: thus the sun gives but does not receive light; fire gives but does not receive heat. Now Christ is the fountain-head of the entire priesthood: for the priest of the Old Law was a figure of Him; while the priest of the New Law works in His person, according to 2 Cor. 2:10: "For what I have pardoned, if I have pardoned anything, for your sakes have I done it in the person of Christ." Therefore it is not fitting that Christ should receive the effect of His priesthood.

Article 5: Whether the priesthood of Christ endures for ever?

It is written (Ps. 109:4): "Thou art a priest for ever."

In the priestly office, we may consider two things: first, the offering of the sacrifice; secondly, the consummation of the sacrifice, consisting in this, that those for whom the sacrifice is offered, obtain the end of the sacrifice. Now the end of the sacrifice which Christ offered consisted not in temporal but in eternal good, which we obtain through His death, according to Heb. 9:11: "Christ is [Vulg.: 'being come'] a high-priest of the good things to come"; for which reason the priesthood of Christ is said to be eternal. Now this consummation of Christ's sacrifice was foreshadowed in this, that the high-priest of the Old Law, once a year, entered into the Holy of Holies with the blood of a he-goat and a calf, as laid down, Lev. 16:11, and yet he offered up the he-goat and calf not within the Holy of Holies, but without. In like manner Christ entered into the Holy of Holies---that is, into heaven---and prepared the way for us, that we might enter by the virtue of His blood, which He shed for us on earth.

Article 6: Whether the priesthood of Christ was according to the order of Melchisedech?

It is written (Ps. 109:4): "Thou art a priest for ever according to the order of Melchisedech."

As stated above () the priesthood of the Law was a figure of the priesthood of Christ, not as adequately representing the reality, but as falling far short thereof: both because the priesthood of the Law did not wash away sins, and because it was not eternal, as the priesthood of Christ. Now the excellence of Christ's over the Levitical priesthood was foreshadowed in the priesthood of Melchisedech, who received tithes from Abraham, in whose loins the priesthood of the Law was tithed. Consequently the priesthood of Christ is said to be "according to the order of Melchisedech," on account of the excellence of the true priesthood over the figural priesthood of the Law.
