I've no time tonight, but I will send you links from a once faithful teacher who was able to teach me the truth on the topic a while back in a live online study group.
Other than that, let er rip on the topic. I'm curious to know what you are seeing.
The short version is that Paul is not actually talking about the Lord's Supper at all!
That just floored me!
Rather, Paul was attempting to convey a spiritual principle unto the ever carnal Corinthians, via a carnal, or an everyday, physical world example - eating and drinking.
It is this same spiritual principle as to our dealings with one another in Him, here in 2 Cor. 5: 13-17.
The Lord had also wanted to convey this spiritual principle - of spiritual unity between the Twelve in Him, that is; via their remembrance of Him that LAST, PHYSICAL, Supper with them, UNTIL He come, which is when He and they will one day be one again with Him in the physical, Matt. 26: 29.
Well, the Body starts out with this spiritual unity principle, Rom. 14:17.
There, I did it - the short version of all I wrote to myself about it, lol
