12. Let us prove that the Passion also of the Son was the work of the Father and the Son. We may see that the Passion of the Son is the work of the Father, since it is written, “Who spared not His own Son, but delivered Him up for us all;” and that the Passion of the Son was His own work also, “Who loved me, and gave Himself for me.” The Father delivered up the Son, and the Son delivered up Himself. This Passion was wrought out for one, but by both. As therefore the birth, so the Passion, of Christ, was not the work of the Son without the Father, nor of the Father without the Son. The Father delivered up the Son, and the Son delivered up Himself. What did Judas in it, but his own sin? Let us then pass on from this point also, and come we to the resurrection.
