This has no effect on Calvinism, Paul uses this very account to demonstrate the peril of those who partake in an unholy manner;
23 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:
24 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.
25 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.
26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
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.
28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
30 For this cause many are weak and sickly among you, and many sleep.
This passage destroys much of Calvinism and no Reformed/Calvinist can really answer it
New King James Version Luke 22:20-22 Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you. But behold, the hand of My betrayer is with Me on the table. And truly the Son of Man goes as it has been determined, but woe to that man by whom He is betrayed!”
