“Can we address this in a civilized manner without resorting to Kabbalah and ad hominem?”
I don’t understand what you are talking about.
In His glorified body He was “flesh and bones” able to be seen, touched and felt. Though material objects did not hinder Him (doors) He was still voluntarily limited by the physical, though glorified, body. He met people in specific geographical places. He ate food and drank with them. He told the disciples He was going away and they would not see Him again until the kingdom, and it was a good thing since then the Holy Spirit would come and bring all things He had taught them to their remembrance. This voluntary taking upon Himself the form of a man was part of the plan from eternity to be economically subordinate to the Father but did nothing to diminish His deity.
Unless he has multiple bodies that are being sliced up and turned into bread and wine he can't be in the communion bread and wine.
I agree with this, Blue Duncan. I am not sure what is it that you and Kosta are arguing about.
