The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
1 Corinthians 10 16
In this verse we see the name I’ve heard most commonly used for the Lord’s Supper: Communion. The word communion carries with it the ideas of fellowship and participation. When we celebrate the Lord’s Supper, we remember Christ’s work on our behalf, and in a sense, fellowship in his sufferings and participate in his death and subsequent victory. His Supper is the communion of the body of Christ.
Now I think it is important that we recognize not only our fellowship with His physical sufferings in some way, but also our fellowship with His body that we can see right now — the church. Communion is the fellowship and participation of the church as it remembers the work of Christ in His death, burial, resurrection and triumphant ascension. This is one reason why we don’t bring communion to people that are not at church. That’s not communion. You have to have an assembly in order to have participation with one another in fellowship.
This is another reason why the Lord’s Supper is necessary for the health of a church. As we partake, we ought to discern the Lord’s body around us. His body that we are a part of. His body that we have mistreated, or slandered, or envied. If we come to His table with these sins in our lives, we should immediately confess and forsake them. We should right them. If we have this understanding of the Lord’s Supper, the more often we partake, the healthier the body will be. This confessing and forsaking is true self-denial, maybe even taking up our cross.
For as often as ye eat this bread, and drink this cup, ye do show the Lord’s death til He come.
The Lord’s Table is His supper celebrated with thanksgiving in communion with other believers because of our fellowship in Christ. We show loyalty to the Lord as we remember His broken body and shed blood, which washes away our sin.
