The celebration of the Lord's Supper in the Jerusalem church was probably connected in some way with "the breaking of bread," which is mentioned in Acts 2:42. Every common meal was an expression of Christian communion, but the solemn words of Christ at the Last Supper could not have been forgotten. Here, as so often, the book of The Acts affords little information about the internal affairs of the Church.
Fortunately, Paul, in the First Epistle to the Corinthians, is far more explicit, and inferences can be drawn from him with regard even to Jerusalem. Paul represents the Lord's Supper, not as an innovation, but as something that had been given to the Corinthians as a matter of course, at the very beginning of their Christian lives; evidently the sacrament was celebrated universally in the churches; Paul had "received" the account of the institution of the Supper from the Lord through the first Christians.
In Corinth, as was also probably the case in the early days in Jerusalem, the Supper was celebrated in connection with the common meals of the Christian community. Certain abuses had arisen; the rich brought food and drink with them and feasted luxuriously in the presence of their poorer brethren; the spiritual significance of the Supper was profaned. Against such abuses Paul enunciates the great principle that the Supper does not work a magical benefit; if partaken of irreverently it brings condemnation rather than blessing.
In I Cor. 10:14-22, the Lord's Supper appears as a warning against participation in heathen feasts. The pagan fellow citizens of the Corinthian Christians, by their religious feasts, held communion with idols; the Christians cannot remain with them and at the same time commune with Christ. A man must take his choice--either Christ or idols; he must choose either the Lord's Supper or heathen feasts. Here the Lord's Supper appears especially as a sign of communion with Christ, as in ch. 11:26 it appears especially as a commemoration of his death. These two aspects of the Supper, and their intimate connection with each other, should now be explained a little more in detail.
=(1) A Representation of the Death of Christ.=--The Lord's Supper, as is observed in the Student's Text Book, is representative of the death of Christ on our behalf. In many passages of the New Testament, the significance of that death is explained in words; in the Lord's Supper it is represented in visible form. The Lord's Supper is related to the story of the gospel, as the picture or the acted representation is related to ordinary discourse. In the broken bread and poured-out wine we not only apprehend with the mind, but actually see the broken body and shed blood of the Lord. Of course that does not mean, as the Roman Catholic Church teaches, that the bread and wine are actually by a miracle, at every celebration of the Supper, changed into the body and blood of Christ, but only that they represent them. The very simplicity of the sacrament should have guarded against misinterpretation. An actual image of the dying Saviour might lead to idolatry, or to an overemphasis upon the details of the scene on Calvary; the simple representation that Christ ordained is enough to be vivid, without being enough to become misleading.
