In Luke’s account of the institution of the Lord’s Supper, the text says in chapter 22:19-20: 19 Then he took a loaf of bread, and when he had given thanks, he broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.” 20 And he did the same with the cup after supper, saying, “This cup that is poured out for you is the new covenant in my blood.
Within Jesus’ words here is something of a twofold structure for how we might understand the salvation God is setting into us; specifically that we are saved from something and saved for something.
In v19, Jesus took the loaf and said “This is my body, which is given for you”. Many times in the New Testament Scriptures, the word “body” is used to describe, yes, our physical bodies, but also the arena in which our struggle with our sinful nature is the most intense. So by instating the bread, Jesus establishes it is by the holy nature of his own body that the fallen nature of our bodies is being redeemed. Thus we who are allegiant to him share in the freedom from sin’s enslaving dominion.
Being liberated from slavery, however, does not yet mean we are empowered for the life of freedom.
So in v20, Jesus then takes the cup and says “This cup that is poured out for you is the new covenant in my blood”. Israel’s failure to keep the old covenant revealed the dominion of sinful nature at work in our fallen flesh. With Christ’s body having liberated us from our fallen nature’s dominion, we are now prepared to enter into a new covenant reality designed to reveal Christ’s holy nature. The institution of the cup, therefore, certifies that in Jesus’ blood is the initiation of that new reality. His blood brings to life the covenant reality those allegiant to him shall display by embodying the harmony of holiness Jesus himself personified and proclaimed.
This twofold structure sets Christ’s redemptive rhythms into our lives. The Communion rite reminds us of who we are in Christ and reinvigorates us for life in Christ. In taking the bread, let us do so remembering his body has saved us from the dominion of sin in our own bodies. As we take the cup, let us do so as committing our allegiance to the holy way of living for which Jesus’ life saves us.
A song lyric of mine goes “From out of the dark, into his kingdom of light, we are made new by his resurrection might”. Communion is not about staying stuck in the patterns of our sin-riddled corpses of yesterday, but embracing God’s covenanted freedom today for the future Christ’s life empowers and propels his people toward.
