The Lord’s Supper is a sacrament, wherein, by giving and receiving bread and
wine, according to Christ’s appointment, his death is showed forth; and the worthy receivers are, not after a corporal and carnal manner, but by faith, made partakers of his body and blood, with all his benefits, to their spiritual nourishment, and growth in grace. Question 96 WSC
Communion is available to all who are part of the bride of Christ and have received the covenant sign of baptism. The apostle Paul warns against a failure to discern the Lord’s body. We understand his use of the Lord’s body to mean the Church; thus we are to be sure we neither give the Lord’s Supper to those who do not love Christ enough to belong to his church, nor are we to exclude any who are in the covenant of the visible church.
The bread is distributed by giving a piece to a designated member of the household, who will then divide and distribute to the rest of the household. The trays of wine (grape juice available on request) are passed down the rows and we eat in unison and drink together proclaiming the Lord’s death until he comes.
But let a man examine himself, and so let him eat of the bread and drink of the cup. For he who eat and drinks in an unworthy manner eats and drinks judgment to himself, not discerning the Lord’s body.
1 Corinthians 11:27-29
