this is an example of rhetoric. The Last supper has nothing to do with the discussion. This is pattantly untrue as even you yourself mentioned Joseph of Aramathea. Its is fair to say Jesus pulled disciples from all walks of life.
Let's look at just this much of what you have said. Throughout your response your standard rebuttal was "this is an example of rhetoric...more rhetoric, etc." You seem to like that word.
Nothing I said about the Lord's Supper was untrue. So let's take this one passage and see what was happening, and hopefully that will prove my point, at least one of them. If I have to, I will go through each one of them in detail like this point by point.
1 Corinthians 11:17-18 Now in this that I declare unto you I praise you not, that ye come together not for the better, but for the worse.
18 For first of all, when ye come together in the church, I hear that there be divisions among you; and I partly believe it.
--The church was divisive. This accusation was mentioned in chapter one, and again here. It was divided into different factions. When the believers came together it was not for good, it was for the worse. The result was worse than had they not gathered at all!
Why was that?
1 Corinthians 11:20-21 When ye come together therefore into one place, this is not to eat the Lord's supper.
21For in eating every one taketh before other his own supper: and one is hungry, and another is drunken.
--Paul has not yet addressed the issue of the Lord's Supper. What he is addressing is a customary "love feast" (modern day pot-luck) that the church had before they gathered to have the service and partake of the Lord's Supper. This is what Paul is addressing. In this feast (not a part of the Lord's Supper), they gathered together is cliques. The rich gathered in their corner, and the poor in theirs. That is what verse 21 indicates. It indicates that the rich would not share of their own with the poor.
Young's Literal Translation put's it this way:
1 Corinthians 11:21 for each his own supper doth take before in the eating, and one is hungry, and another is drunk;
--Each one his OWN supper does take.
One is hungry; the other drunk. Why is one hungry or one group hungry?
Because the rich won't have anything to do with him. They shun them.
Here's the stern rebuke:
1 Corinthians 11:22 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.
--Paul is not rebuking the Lord's Supper; but rather this "love feast."
They have their own houses to eat and drink in. They should stay home if they are going to act like this. In their actions "they despise the church of God," Paul says.
They "shame those that have not," he continues.
His hard lined rebukes continue throughout the verse.
The rich did not welcome the poor into their places of worship.
As far as they were concerned it was better if they had not showed up at all. That was their attitude.
From verses 23 to 26 he explains the importance of the Lord's Supper.
Then he comes back to his rebuke of the rich, and their abuse of the Lord's Supper in showing up in church with this attitude of partiality.
1 Corinthians 11:27 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.
--To drink of the cup; to eat of the bread
unworthily, would bring judgment upon oneself.
Therefore it is important to examine your heart first. The Lord's Supper is a sacred institution, not to be taken lightly
1 Corinthians 11:28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
--Be sure and examine yourself. Don't take of the Lord's Supper if there is sin in your life. Make sure your heart is right before God. This is a serious and sacred ordinance that God has ordained.
1 Corinthians 11:29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
--If you have this flippant attitude and take things lightly you will certainly bring the judgment of God upon yourselves. That is what happened at the church of Corinth.
1 Corinthians 11:30 For this cause many are weak and sickly among you, and many sleep.
--Many were physically weak.
Many were sick.
And many were killed by God Almighty because of their attitude in coming to the church to have a good time, eating and drinking, and shunning the poor all that time, and then still expect to partake of the Lord's Supper afterward. Totally sacrilegious!
