I find it very interesting that of the two parts of communion the one that is left out is the blood, by which we have forgiveness and redemption.
Without the shedding of blood, there is no remission of sins, and yet eliminating the drinking of the cup removes the recognition and the remembrance of the blood sacrifice by which we are saved. It removes the focus from that which is most essential.
I find it interesting that you think that Christ is divisible and not wholly present under the appearance of either the bread or of wine in the Eucharist and that you think that the Blood of Christ is not offered. But then again none of us are done learning, are we?
Peace be with you.
