It's unfathomable to me. How can I? What are You asking me, Lord?
One of my "cloistered brothers", helping to facilitate RCIA, said he can't think when he receives Communion. He receives in his hand, and he feels he should say a prayer of thanksgiving, or praise, or something. But he's just dumbstruck. He can't get over the fact that He has God in his hands; the One who has him in His hands.
