Apoc. 1:5: "He washed us from our sins in His own blood."
Consequently, Christ's Passion even more than His Resurrection is the
cause of the resurrection of souls.

_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, for
