as often as you shall eat this bread, and drink the chalice, you shall shew the death of the Lord, until he come (1 Cor 11:26)St. Paul did not subscribe to the yearly Communion idea.
He did. 1 Corinthians 11:26 simply means "every time you do this you show his death". Many versions of the bible translate it this way.
It doesn't say "do this as often as you can". If that were the sense than it would be "better" to be constantly doing it.
It's no accident that Paul, in the same letter, commanded the Christians at Corinth to observe the feast of Passover and unleavened bread:
1Co 5:7 Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed Christ, our Passover, was sacrificed for us.
1Co 5:8 Therefore let us keep the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.
It was getting close to the time of year when they were going to be observing the passover. As part of that Paul was giving instructions on the wine and the bread.
