Chapter 7 — Part I: The Creed — Article V: He Descended into Hell; the Third Day He Rose Again from the Dead
Section 31. Again, the Resurrection of Christ effects for us the resurrection of our bodies not only because it was the efficient cause of this mystery, but also because we all ought to arise after the example of the Lord. For with regard to the resurrection of the body we have this testimony of the Apostle: By a man came death, and by a man the resurrection of the dead. In all that God did to accomplish the mystery of our redemption He made use of the humanity of Christ as an effective instrument, and hence His Resurrection was, as it were, an instrument for the accomplishment of our resurrection.
