I just wanted to add to this.
This is the record of the first Lord's table, and it is intersting to note who was invited.
20 Now when the even was come, he sat down with the twelve.
21 And as they did eat, he said, Verily I say unto you, that one of you shall betray me.
22 And they were exceeding sorrowful, and began every one of them to say unto him, Lord, is it I?
23 And he answered and said, He that dippeth his hand with me in the dish, the same shall betray me.
24 The Son of man goeth as it is written of him: but woe unto that man by whom the Son of man is betrayed! it had been good for that man if he had not been born.
25 Then Judas, which betrayed him, answered and said, Master, is it I? He said unto him, Thou hast said.
26 And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body. note
27 And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.
If you notice, Jesus sat down "with the twelve". It is very specific: not just "the disciples", but the twelve.
There was certainly a restriction on the first one.
