There have been frequent arguments in church history about what exactly happens at the Lord’s Table. Most of these arguments have come from motivations to value Christ’s work on the cross and in communion, though not all of the arguments can be true.
In 1 Corinthians 10 Paul helps us see the nature of the Supper through his comparisons with two other types of worship meals.
Example one: “Consider the people of Israel: are not those who eat the sacrifices participants in the altar?” (verse 18) But where are the arguments about transubstantiation or consubstantiation when it came to the various offerings eaten by the Jews? Those arguments don’t exist. The sharing in the sacrifice did not happen because the molecules of the meat or the grain were changed or mixed.
Example two: “what pagans sacrifice they offer to demons and not to God. I do not want you to be participants with demons” (verse 20). The same sharing is happening and, again, the sharing happens without the substance of the elements being transformed.
So, when we participate in the blood of Christ by drinking the cup, and when we participate in the body of Christ when we eat the bread, there is a real and supernatural and substantive sharing in Christ’s sacrifice. But it not because the wine or the bread change substance, or even because the spiritual presence of Jesus shows up in the wine or the bread. By faith we partake of the Table, and we are associated with Christ and with all that His sacrifice accomplished in and among us.
