The downward and inward move of God in the Incarnation of Christ brings an end to any religion that would make prayer into a mere head-trip. The Incarnation is an invitation to touch God, taste God, love God. It is first-hand and personal experience of the God who is ultimate reality, and it is the experience of this Reality in our bodies, on this earth.
This radical embodiment of God in Jesus makes all bodies, indeed, all matter—the earth included—sacred.
