We are blessing to partake in this meal weekly, and as we approach it with a careful biblical understanding, we realize that there is a profound Christian mysticism here.
“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? For we being many are one bread, and one body: for we are all partakers of that one bread” (1 Cor. 10:16–17).
We are not just forgiven because we have been cleansed by the blood of Jesus Christ. We are also told here that we have koinonia-fellowship together in the blood of Christ. We are joint-partakers of that blood. We are not simply united together because we have a common religious interest and shared theological opinions. We are one, united together, because we have koinonia-fellowship together in the body of Christ.
All of this happens through the agency and work of the Holy Spirit. The Son of God dwells in Heaven. His Spirit has been poured out on us here. That Spirit is what empowers us to be united with God through faith in His declared Word, and to be woven together with Him in the koinonia-sharing of His body and blood.
Some have been tempted to think that we become the body of Christ through eating and drinking the body of Christ in communion. It would be more to the point to realize that ordinary bread and wine is taken up into this mystery because the body and blood of Christ eats the bread and drinks the wine. How does wine become Christ? As the body of Christ drinks it. How does bread become Christ? As the body of Christ eats it.
So come, and welcome, to Jesus Christ.
