Divine Liturgy V: We become what we receive, amen, amen.
It's an old, old truism that "you are what you eat." Before us, appearing in the lowly form of bread, is the Lamb of God who takes away the sin of the world, and we are invited to come and eat. We know we are not worthy of such a great and awe-filled privilege, but we also know that it's not so much an invitation as it is a command --- we must eat and drink if we are to live. So, as we begged at the very beginning, we ask again, only say the word, my Lord, and I shall be healed. And we come, and bow, and eat. I, a member of the body of Christ, receive the body of Christ. Receiving the body of Christ, we become the body of Christ. And, just as Christ shared in our humanity, we shall share in His divinity.
We are filled with Him, and may be even overcome with awe; there's a reason that many of us bury our face in our hands when we return to our places and pray and await as the other members of Christ's body who are gathered here with us receive the body of Christ also. And in respect, when physically possible, we stay kneeling or standing, not sitting down, until everyone has received and any leftover Hosts have been reposed. And we abide in the closest personal relationship possible with the Lord Jesus Christ, in great recognition of His Body, and we give thanks.
