1 Corinthians 11 v 20-21


1 Corinthians 11:20-21 
(20)  When ye come together therefore into one place, this is not to eat the Lord's supper. 
(21)  For in eating every one taketh before other his own supper: and one is hungry, and another is drunken. 


11:20-21. The Lord’s Supper should have been the remembrance of a preeminently selfless act, Christ’s death on behalf of others. Instead the Corinthians had turned the memorial of selflessness into an experience of selfishness and had made a rite of unity a riotous disunity. While one brother went hungry because he lacked the means to eat well, another brother drank to excess.
