What Paul is doing here – under the inspiration and direction of God – is that he is separating the fellowship meal from the Lord’s Supper. In Corinth evidently they had combined the two.
We do not want too many fellowship meals in a church. We have our homes and our families for eating and drinking. From time to time there may be a fellowship meal for fellowship. It may be that it is convenient on the Lord’s Day for quite a lot of people to eat in the middle of the day, but that is for practical reasons, and it is supposed to be kept as simple as possible. It is for practical reasons: especially so that we can staff the Sunday schools, and carry out evangelistic work. But it isn’t for the sake of eating and drinking.
The so-called house church movement in this country which has been going for some decades now; they make a great thing of fellowship suppers, and they insist that the fellowship supper and the Lord’s Supper may be united; they do this in total defiance to the apostle’s words here. They mean well, but it is not right, and it is not Scriptural. Many, many charismatics do the same thing: fellowship supper and Lord’s Supper. They kind of give the game away in that you find their writers saying, ‘Oh, these Lord’s Supper meetings in the traditional churches are like going to a funeral. We want the Lord’s Supper to be merged with a fellowship meal, with more jollity, more like a wedding feast. That is what it should be like,’ they say, ‘a wedding supper, a wedding feast.’ Oh no. The Lord’s Supper is not supposed to be like a funeral, certainly, but it is to be serious. It is deep appreciation of the Lord and his work, and we keep tenaciously to the tradition which was begun on the authority of the inspired apostle, to keep the fellowship occasions separate from the Lord's Supper.
