Rev. Eppard, our practice at CCRPC is to come and sit at a table. There is a former thread on the PB where this has been discussed, and works defending the practice referenced. The point of sitting at a table, as these works relate, is that we sit as invited and (although unworthy) honored guests at the family table of our King and Elder Brother--that the use of a table spoke of great privilege in the ancient near east, and even retains a measure of that privilege today is, I believe, something we all recognize (think of the invited guests to the King's table in the days of Saul, and the scene at Sinai in Exodus 24 where the elders of Israel, as representatives of the nation, sat at table to enjoy a meal of acceptance and communion before God Himself). We sit as family members, facing one another in that table arrangement, where we look one another in the face, and place our feet under the same table as a family, as we consider our communion with one another in Christ. Truly, this is more in keeping with the Greek original, transliterated koinwnia, fellowship, communion, with one another in Christ. As a review of the works mentioned above will show, the practice of communing in pews with our backs to one another as a congregation tends to work against that understanding, and individualizes, rather than makes a "communion" of the table. I am aware that you in all likelihood do not agree with the above. This is not an attempt on my part to debate you, only to answer your assertion, "I don't see the point of sitting around a table".We have a communion table in the front that we put the elements on. We either distribute it to the congregation in the pews or have them come up front. I don't see the point of sitting around the table. Even if it was defended practice doesn't make it proper. People have done a lot of illogical and silly things in the name of religion. If a church is going to do this, and it is their right to choose to do so, then why not just serve communion when you have a fellowship dinner? This would make the most sense if you are going to sit at a table.
I wish there was a bit more here about the practicalities, but by looking at the building where Calvin preached, I assume his congregation was quite large?A plain table was brought in and communicants sat or knelt about it. Eventually, sitting about the Lord's Table came to be the distinctive Reformed posture for receiving the Lord's Supper and continues so today in the Netherlands. This practice made it easy to repel the notorious sinner from a seat at the table.
