This is the only religion I know of that actually acts out the last supper in the fashion of the first church .
many interesting points you have, but the above one is wrong, because when Jesus passed the emblems, none of his disciples were anointed. Even he expressed himself as one with an Earthly hope, "sitting on tables, drinking wine himself in the kingdom, ruling Israel". So to follow Jesus, all should partake. who knows they might be anointed later. or worse, the anointed should not partake, because the only anointed at the last supper, Jesus, did not.
The big problem, and you will come to that, perhaps, is, that it is all stories. There never was a talking snake,or donkeys, An Ark floating above Everest, Millions trekking in the desert for 40 years. Jonah eaten by a fish, the Earth standing still or even rotating backward, people walking on water, people coming out of the graves and invading Jerusalem.
These are stories on the credibility level of Little Red Riding Hood and the big bad Wolf. badly written bible babbel.
don't take it too seriously for too long.
If there is a communion tradition, fine, let the anointed serve and the OS eat and drink.
P.S. sorry you mentioned the Early Church, and I described the original last Supper, , already a difference had developed.
