With a bit of sarcasm, Paul then wrote," When you come together it is not the Lord's supper you eat,
for as you eat, each of you goes ahead without waiting for anybody else"
(verses 20-21)

Paul was not commenting about the terminology used for the ceremony.
He was explaining that even though the Corinthian members where observing the service,
their internal divisions and animosity kept them from observing it in the proper spirit.
