1 Corinthians 11:23-26 "For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread; 24 and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” 25 In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.” 26 For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes."
"(I)f baptism may be compared to a wedding ceremony, the Lord's supper may be compared to an anniversary celebration in which the vows taken at the wedding are renewed. Renewal takes place in the supper on a number of levels. First, the remembrance of our Lord's death should lead to a renewal of our repentance, because we remember that His body was broken to free us from sin. How can we live in sin when His body was broken to liberate us? Second, the supper should be an occasion to renew our faith. In partaking of it, we 'proclaim the Lord's death' (1 Cor 11:26). We remember that death is our only hope, and we renew our commitment to trust in Christ alone. That faith focuses on His death, the body broken and the blood shed, but it also emphasizes His resurrection, victory over death and promised return. As this document puts it, in the Supper we 'anticipate His second coming.' Finally, the Lord's Supper is also an occasion for renewing our commitment to the church. 1 Corinthians 11:18 see the Lord's Supper as a time when the church 'comes together.'"
I really like how the authors track out the idea of the Lord's supper being a repeated act of renewal. Whenever we see the phrase "symbolic act", we must not view the Lord's supper as an empty symbol or church ritual. Far from it. Partaking of the Lord's Supper is how the Lord Jesus Christ through the Person of the indwelling Spirit in each Christian reminds them of who they are and Whose they are. Jesus is especially present in and through His people when they do so, as He promised He would be with His church in passages such as Matthew 28:18-20. The "symbolic" nature of the supper is really a "sign" pointing to an abiding reality, that wherever the church is gathered, Jesus by His Spirit is present in them and through them.
