In Communion, do we commune with the sacrificed body and blood of Jesus, or do we commune with the resurrected body and blood of Jesus?
ANSWER: The answer to your question is that we receive in, with, and under the bread and wine the true body and blood of Christ shed on the cross, Jesus Christ Who is now risen and ascended and sits at the right hand of God the Father.
He is the same Christ, and when he gave us the Sacrament, as the Lutheran Confessions affirm, "he was speaking of his true, essential body, which he gave into death for us, and of his true, essential blood, which was poured out for us on the tree of the cross for the forgiveness of sins" (Formula of Concord, Solid Declaration VII, 49).
In the Sacrament, our Confessions further teach the same Jesus who died is present in the Sacrament, although not in exactly the same way he was corporeally present when he walked bodily on earth.
With Luther, the Formula of Concord speaks of "the incomprehensible, spiritual mode of presence according to which he neither occupies nor yields space but passes through everything created as he wills ... He employed this mode of presence when he left the closed grave and came through closed doors, in the bread and wine in the Supper ..." [FC SD VII, 100; emphasis added]
