Part III

, ch. i, anath. 10] we read: "If anyone say that the very Word of God did not become our High-Priest and Apostle, when He became flesh and a man like us, but altogether another one, the man born of a woman, let him be anathema." Hence in so far as His human nature operated by virtue of the Divine, that sacrifice was most efficacious for the blotting out of sins. For this reason Augustine says (De Trin. iv, 14): "So that, since four things are to be observed in every sacrifice--to whom it is offered, by whom it is offered, what is offered, for whom it is offered; the same one true Mediator reconciling us to God by the sacrifice of peace, was one with Him to Whom it was offered, united in Himself those for whom He offered it, at the same time offered it Himself, and was Himself that which He offered."

Reply Obj. 2: Sins are commemorated in the New Law, not on account of the inefficacy of the priesthood of Christ, as though sins were not sufficiently expiated by Him: but in regard to those who either are not willing to be participators in His sacrifice, such as unbelievers, for whose sins we pray that they be converted; or who, after taking part in this sacrifice, fall away from it by whatsoever kind of sin. The Sacrifice which is offered every day in the Church is not distinct from that which Christ Himself offered, but is a commemoration thereof. Wherefore Augustine says (De Civ. De. x, 20): "Christ Himself both is the priest who offers it and the victim: the sacred token of which He wished to be the daily Sacrifice of the Church."

Reply Obj. 3: As Origen says (Sup. Joan. i, 29), though various animals were offered up under the Old Law, yet the daily sacrifice, which was offered up morning and evening, was a lamb, as appears from Num. 38:3, 4. By which it was signified that the offering up of the true lamb, i.e. Christ, was the culminating sacrifice of all. Hence (John 1:29) it is said: "Behold the Lamb of God, behold Him Who taketh away the sins [Vulg.: 'sin'] of the world." _______________________

FOURTH ARTICLE [III, Q. 22, Art. 4]

Whether the Effect of the Priesthood of Christ Pertained Not Only to Others, but Also to Himself?

Objection 1: It would seem that the effect of the priesthood of Christ pertained not only to others, but also to Himself. For it belongs to the priest's office to pray for the people, according to 2 Macc. 1:23: "The priests made prayer while the sacrifice was consuming." Now Christ prayed not only for others, but also for Himself, as we have said above (Q. 21, A. 3), and as expressly stated (Heb. 5:7): "In the days of His flesh, with a strong cry and tears He offered [Vulg.: 'offering'] up prayers and supplications to Him that was able to save Him from death." Therefore the priesthood of Christ had an effect not only in others, but also in Himself.

Obj. 2: Further, in His passion Christ offered Himself as a sacrifice. But by His passion He merited, not only for others, but also for Himself, as stated above (Q. 19, AA. 3, 4). Therefore the priesthood of Christ had an effect not only in others, but also in Himself.

Obj. 3: Further, the priesthood of the Old Law was a figure of the priesthood of Christ. But the priest of the Old Law offered sacrifice not only for others, but also for himself: for it is written (Lev. 16:17) that "the high-priest goeth into the sanctuary to pray for himself and his house, and for the whole congregation of Israel." Therefore the priesthood of Christ also had an effect not merely in others, but also in Himself.

_On the contrary,_ We read in the acts of the Council of Ephesus [*
