SIXTH ARTICLE: REDEMPTION BY WAY OF EFFICIENCY

State of the question. St. Thomas inquires in this article whether Christ's passion brought about our salvation by way of efficiency. The query is not concerned with what constitutes the work of redemption, but with what follows from it as a part of the effect to be produced. It does not pertain to the faith as the preceding queries do, but belongs properly to theology.

It concerns not only moral causality, as being the causality of merit awaiting the effect from another, but also efficient and physical causality, which produces the effect. We have already seen[1975] that Christ's soul, inasmuch as it is the instrument united with the Word, had and has instrumental power to produce supernatural effects.[1976]

Yet there remains a special difficulty for Christ's passion, which could not be the case with any man; for no corporeal agent acts except by actual contact. Moreover, Christ's passion is no more, and therefore it cannot operate efficiently; for that which no longer exists, no longer operates physically.

Reply. Yet the answer is that Christ's passion efficiently causes our salvation, not indeed as principal cause, but as instrumental cause.

Theological proof. Christ's humanity is the instrument of His Godhead, with which it is united. Therefore, as a consequence of this, all Christ's actions and sufferings operate instrumentally in virtue of His Godhead for the salvation of men.

Reply to first objection. It explains the words of the Apostle: "The weakness of God is stronger than men."[1977]

Reply to second objection. "Christ's passion although corporeal, has yet a spiritual effect from the Godhead united, and therefore it secures its efficacy by spiritual contact." Corporeal contact is not required, but virtual or dynamic contact suffices. We find this to be true of several instruments used by man, as in the use of a trumpet to transmit a sound in a certain direction; for this instrument does not actually touch the ears of the hearers. A fortiori, God makes use of similar instruments to produce spiritual effects.

The objection that Christ's passion no longer is in action, and therefore cannot operate efficiently, is of no value; for it is a question of Christ's humanity, as formerly subject to suffering and now persists in His glorified wounds. Such is the explanation given by the holy doctor.[1978]

Reply to third objection. It is a recapitulation of this subject about Christ's sufferings, for it says: "Christ's passion, according as it is compared with His Godhead, operates in an efficient manner, but so far as it is compared with the will of Christ's soul it acts in a meritorious manner, considered as being within Christ's very flesh, it acts by way of satisfaction, inasmuch as we are liberated by it from the debt of punishment; while inasmuch as we are freed from the servitude of guilt, it acts by way of redemption; but so far as we are reconciled with God it acts by way of sacrifice."
