Whether it is proper to Christ to be the Redeemer?

Objections

Objection 1 : It would seem that it is not proper to Christ to be the Redeemer, because it is written (Ps. 30:6): "Thou hast redeemed me, O Lord, the God of Truth." But to be the Lord God of Truth belongs to the entire Trinity. Therefore it is not proper to Christ.
Objection 2 : Further, he is said to redeem who pays the price of redemption. But God the Father gave His Son in redemption for our sins, as is written (Ps. 110:9): "The Lord hath sent redemption to His people," upon which the gloss adds, "that is, Christ, who gives redemption to captives." Therefore not only Christ, but the Father also, redeemed us.
Objection 3 : Further, not only Christ's Passion, but also that of other saints conduced to our salvation, according to Col. 1:24: "I now rejoice in my sufferings for you, and fill up those things that are wanting of the sufferings of Christ, in my flesh for His body, which is the Church." Therefore the title of Redeemer belongs not only to Christ, but also to the other saints.
