God addresses us in his Word. We see his promise ratified in baptism and receive Christ’s sacrifice afresh in the Supper. Paul reminds us that Communion links us to Christ’s sacrifice in the past (I Corinthians 11:24-25). It also directs us to the future: “For as often as you eat this bread and drink this cum, you proclaim the Lord’s death until he comes again” (I Corinthians 11:26) Even in the present we fed on Christ’s body and blood by faith: “The cup of blessing, which we bless, is not a participation in the blood of Christ? The bread which we break , is it not a participation in the body of Christ?” (I Corinthians 10:16). Connected together to our Living Head in heaven, we are joined together as one body on earth: “For we, though many, are one bread and one body; for we all partake of that one bread” (I Corinthians 10:17).
