Bible S., The above isn't scripturally true. Paul in addressing the 1Corinthians (11:22-29) concerning the Communion supper acknowledged that it was for/by the congregation as a whole.
"""What? have ye not houses to eat and to drink in? or despise ye the church of God, and shame them that have not? What shall I say to you? shall I praise you in this? I praise you not.
For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.
After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.
For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
But let a man examine himself, and so let him eat of that bread, and drink of that cup.
For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body."""
Your posted scriptures are true, but your conclusive applications are false.
Paul wrote in that same book(10:6, 11) and Rom.15:4 That what was written is for examples, admonition, and learning by US.
Jesus(nor GOD the Father) is not a respecter of persons. Your Site is wrong in its conclusions.
