The Table of the Lord humbles the honest, comforts the distraught, forgives the repentant, nourishes the hungry, establishes the church, preaches the gospel, summons the world, and overwhelms the devil.
And of course the Table as a mere set of physical objects does none of those things—any more than the Word of God, considered simply as paper and ink, does such things.
When the preached Word pierces the heart of a treacherous or hypocritical Christian, and he repents, no one thinks to attribute the power of the Word to the fact that it was leather-bound, and When some poor forsaken sinner picks up a Gideon Bible in a hotel somewhere, and turns to Christ, no one thinks it was the power of the binding, or paper, or publishing house. We attribute it all to the power and goodness of God, who moves and works through such things.
In the same way, as the Supper of the Lord deals with us—rebuking us, strengthening us, admonishing us, revealing our sin, establishing us in love for one another—no one in their right mind would attribute the power of this to the grocery store where we bought the wine, or the bakery where we obtained the bread. And neither is the power to be found in the bread or the wine. These things correspond exactly to the paper and ink of the Scriptures.
What are they apart from faith? The letter kills, but the Spirit brings life. Words as words bring nothing but condemnation. Bread as bread, wine as mere wine, are nothing but a ministry of death. What are they apart from faith alone? They are nothing but increasing condemnation.
As so, as children of faith, you are summoned to come. You are summoned so that your evangelical faith would be nourished and strengthened by the bread and wine, not replaced by the bread and wine. When faith comes to the Table, faith is always an essential part of the picture.
