Whether the sacraments of the New Law derive their power from Christ's Passion?

❌ Objection 1 : It seems that the sacraments of the New Law do not derive their power from Christ's Passion. For the power of the sacraments is in the causing of grace which is the principle of spiritual life in the soul. But as Augustine says (Tract. xix in Joan.): "The Word, as He was in the beginning with God, quickens souls; as He was made flesh, quickens bodies." Since, therefore, Christ's Passion pertains to the Word as made flesh, it seems that it cannot cause the power of the sacraments.

❌ Objection 2 : Further, the power of the sacraments seems to depend on faith. for as Augustine says (Tract. lxxx in Joan.), the Divine Word perfects the sacrament "not because it is spoken, but because it is believed." But our faith regards not only Christ's Passion, but also the other mysteries of His humanity, and in a yet higher measure, His Godhead. Therefore it seems that the power of the sacraments is not due specially to Christ's Passion.

❌ Objection 3 : Further, the sacraments are ordained unto man's justification, according to 1 Cor. 6:11: "You are washed . . . you are justified." Now justification is ascribed to the Resurrection, according to Rm. 4:25: "(Who) rose again for our justification." Therefore it seems that the sacraments derive their power from Christ's Resurrection rather than from His Passion.
