The Lord's Table
1 Corinthians 11.23-26
"For I have received of the Lord that which also I delivered unto you, that the Lord Jesus the night in which He was betrayed took bread: and when He had given thanks, He broke it, and said, 'Take, eat: this is My body, which is broken for you: this do in rememberence of me.' After the same manner also the cup, when He had eaten, saying, 'This cup is the New Testament in my blood: do this as often as you drink, in rememberence of Me'. For as often as you eat this bread, and drink this cup, you show the Lord's death till He come."On the night of His betrayal, our Master identified during the Passover Meal, a tradition passed on (παραδοσις) through the Apostles, to His church. This tradition has been called, 'Communion', 'Remembrance Meeting', 'The Lord's Supper', and 'The Lord's Table'.
Each of these names have Scriptural precedence. "Communion", comes from 1Co 10.16, quoted above. "Remembrance Meeting" comes from 1Co 11.24-25, in the Lord's command, "do this in rememberence of Me." "The Lord's Table" comes from 1Co 10.21, a description of Paul. And while "The Lord's Supper" has Scriptural grounding (1Co11.20), it appears to be a mistranslation. For, the wording here is literally, "a lordly meal (κυριακον δειπνον)", chastising the Corinthian gathering, and the lavishness of some, while excluding others.
The purpose of this "rememberence" seems clear enough -- it is a periodic gathering in which those who have immersed into the Lord's death (Rom 6.3), profess their continued sharing in the Body and Blood of Jesus Christ. In this rememberance, we also contemplate our own behavior, judging ourselves so we do not need to be judged by the Lord.
Above was stated that this was a periodic meal. Some practice this tradition annually, on the Passover, as this was the day the Lord identified this practice. Some do so weekly, as became the tradition of the assemblies out of Rome from a very early time. And others follow various schedules such as monthly, or every 5th Sunday.
Concerning many who practice this each Sunday, some base this on their understanding of Acts 20.7, which is commonly translated into English as, "And upon the first day of the week, when the disciples came together to break bread...". This understanding may also be based upon a mistranslation, and the tradition handed down by Rome.
