Conduct in Public Worship. 1 Cor. 11, 26–27
Worthy and unworthy communicants: V. 26. For as often as ye eat this bread and drink this cup, ye do show the Lord's death till He come. V. 27. Wherefore, whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
The apostle now gives the Christians of Corinth and of all times some rules as to the proper preparation for, and celebration of, the Holy Communion. One of its purposes, as just stated by Paul, was that it should serve for the commemoration of the Lord.
But frequency of celebration and familiarity with the Eucharist was not to blunt the reverence for its sanctity. Therefore the apostle says: For as often as you eat this bread and drink the cup, the death of the Lord you proclaim until He comes.
Every celebration of the Eucharist is an open proclaiming, a publishing of the death of the Lord, of the fact that by the giving of His body and by the shedding of His blood He has wrought redemption. Of course, the right attitude toward the Sacrament is that in which the heart is fully conscious of the blessings which the mouth confesses. That fact will make every communicant both humble and eager for the wonderful grace of God, as given in the Holy Communion. Until He comes, until He returns in glory, the Sacrament of His body and blood is to be the means of communication from Him to us.
But the wonderful content and purpose of the Holy Communion demands, at the same time, a most careful preparation on the part of the communicant: So that whoever eats the bread, or drinks the cup of the Lord, unworthily, guilty is he of the body and blood of the Lord.
To eat unworthily is to be in such a spiritual condition or to conduct oneself in such a manner as to be out of harmony with the dignity and the sanctity of the heavenly meal. Should a person come to the Lord's Supper as he would go to any other meal, considering his actions to be the mere eating of bread and the mere drinking of wine, if he feels neither desire for the grace of God nor devotion at the prospect of partaking in the miracle feast, then such a person will be guilty, not merely of a thoughtless eating and drinking, but of desecration of the body and blood of the Lord. He will show that he has neither a conception of his sinfulness nor a longing for the grace of God; and thus his guilt will consist in his hindering the grace of God in the Sacrament, which is ready to bestow upon him forgiveness of sins, life, and salvation.
