Yes, Jesus Christ is the center of all of God’s saving work, because the Father chose Him to be so in view of His Incarnation, birth, Death, and Resurrection.
Jesus Christ became man so that He might save all men and re-establish in Himself all things which were hurt by the fall of man. Thus, by His Death and Resurrection, He was given by His Father all power in Heaven and on earth, and He founded the Catholic Church as the means of our Salvation. In Christ, our Savior and Redeemer, we are united to all men. Jesus said, “The Father loves the Son, and has given all things into his hand. He who believes in the Son has eternal life” (John 3:35-36).
The whole work of Salvation receives its meaning from Jesus Christ, the Incarnate Word. That work, beginning with the Creation, showed itself in Christ’s coming, in His life on earth, and in His Death and Resurrection, and it will be completed in His glorious Second Coming. Thus, God was powerfully at work in the history of Israel, and in the life, Death and Resurrection of His Incarnate Son.
