Today, Christ exacts our obedience. The "letter to the Hebrews" describes Old Testament worship as a "shadow" in view of the inadequacy of animal sacrifices that God does not require and which man does not give God what He might expect from man. Authentic worship of God is to be found within a life marked by His Word.

However, our obedience is always lacking. Our personal morality is not enough to properly worship God. For this reason the Son of God becomes flesh; He takes on a human body. In this way a new obedience becomes possible, an obedience that surpasses all human fulfillment of God’s Commandments. The Son becomes man and in His Body bears the whole of humanity back to God. Only the incarnate Word, whose love is fulfilled on the Cross, is perfect obedience of the Son; it is the new sacrifice.

—O Jesus, You who are God incarnate, take us all with you and offer what we could not give just by ourselves.
