Q: Whether Christ's Resurrection Is the Cause of the Resurrection of Souls?

A: On the contrary,
The Apostle says (Rom. 4:25): "He rose again for our justification," which is nothing else than the resurrection of souls: and on Ps. 29:6: "In the evening weeping shall have place," the gloss says, "Christ's Resurrection is the cause of ours, both of the soul at present, and of the body in the future."

I answer that,
As stated above, Christ's Resurrection works in virtue of the Godhead; now this virtue extends not only to the resurrection of bodies, but also to that of souls: for it comes of God that the soul lives by grace, and that the body lives by the soul. Consequently, Christ's Resurrection has instrumentally an effective power not only with regard to the resurrection of bodies, but also with respect to the resurrection of souls. In like fashion it is an exemplar cause with regard to the resurrection of souls, because even in our souls we must be conformed with the rising Christ: as the Apostle says (Rom. 6:4-11) "Christ is risen from the dead by the glory of the Father, so we also may walk in newness of life": and as He, "rising again from the dead, dieth now no more, so let us reckon that we (Vulg.: 'you')" are dead to sin, that we may "live together with Him."

Reply Obj. 1: Augustine says that the resurrection of souls is wrought by God's Substance, as to participation, because souls become good and just by sharing in the Divine goodness, but not by sharing in anything created. Accordingly, after saying that souls rise by the Divine Substance, he adds: the soul is beatified by a participation with God, and not by a participation with a holy soul. But our bodies are made glorious by sharing in the glory of Christ's body.

Reply Obj. 2: The efficacy of Christ's Resurrection reaches souls not from any special virtue of His risen body, but from the virtue of the Godhead personally united with it.

Reply Obj. 3: The resurrection of souls pertains to merit, which is the effect of justification; but the resurrection of bodies is ordained for punishment or reward, which are the effects of Him who judges. Now it belongs to Christ, not to justify all men, but to judge them: and therefore He raises up all as to their bodies, but not as to their souls.

Reply Obj. 4: Two things concur in the justification of souls, namely, forgiveness of sin and newness of life through grace. Consequently, as to efficacy, which comes of the Divine power, the Passion as well as the Resurrection of Christ is the cause of justification as to both the above. But as to exemplarity, properly speaking Christ's Passion and death are the cause of the forgiveness of guilt, by which forgiveness we die unto sin: whereas Christ's Resurrection is the cause of newness of life, which comes through grace or justice: consequently, the Apostle says (Rom. 4:25) that "He was delivered up," i.e. to death, "for our sins," i.e. to take them away, "and rose again for our justification." But Christ's Passion was also a meritorious cause, as stated above (A. 1, ad 4; Q. 48, A. 1).

QUESTION 57

OF THE ASCENSION OF CHRIST (In Six Articles)

We have now to consider Christ's Ascension: concerning which there are six points of inquiry:

(1) Whether it belonged for Christ to ascend into heaven?

(2) According to which nature did it become Him to ascend?

(3) Whether He ascended by His own power?

(4) Whether He ascended above all the corporeal heavens?

(5) Whether He ascended above all spiritual creatures?

(6) Of the effect of the Ascension.
