It is more than possible that at least some of the Corinthians had participated in the worship of Dionysius, also known to the Romans as Bacchus. Bacchus was the god of wine and festivity and fertility, a god well known and served for centuries before Christ came. In the name of Bacchus men and women became drunk and in many cases caused destruction through frenzy and ritual unrestraint. Some of the Corinthian Christians may have brought this baggage with them to their fellowship meals.
Paul went out of his way in Ephesians 5:18 to contrast being filled with the Spirit to being filled with, another way to say “controlled by,” wine: “do not get drunk with wine, for that is debauchery, but be filled with the Spirit” (Ephesians 5:18).
But it is interesting to see the results of that Spirit-filling: “addressing one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with all your heart, giving thanks always and for everything to God the Father in the name of our Lord Jesus Christ” (Ephesians 5:19-20). This does not sound like the death of Bacchus, it sounds like his salvation and submission to Christ. The opposite of Dionysian madness and indulgence isn’t commiseration, but melody and thankfulness.
Worshipped as a god, everything brings damnation. Seen as a servant of God, all lawful things are good for God’s glory. So were the Corinthians behaving inconsistently at the Lord’s supper? Absolutely. What would have made it consistent? Consistent would not have been misery instead of revelry, consistent would have been loving God and others joyfully in remembrance of Christ.
