The Lord’s Supper is a sacrificial meal, which is not the same thing as a sacrifice. The Lord Jesus offered Himself on the cross two thousand years ago, and when He ascended into heaven some weeks afterward, at that time He presented His sacrifice in the heavenly places, in the ultimate Holy of Holies. His sacrifice was a once for all atonement. But in the Bible, sacrifices have blessings that flow from them—which are distinct from the sacrifice, but not separable from it.
Because this is a sacrificial meal, it has to be understood as something God is giving to us. If we do not understand it this way, then we will of necessity turn it into something that we are rendering to God. Of course, the Roman church thinks of this table as an altar, and the bread and wine and a sacrifice proper. But most of the modern evangelical world thinks of it in the same way. The offering of man to God in this case is a testimony, or a dedication, or a confession, or something offered up to Him. The thing they share in common is the view that man is somehow a priest in this, and offers a sacrifice of some sort to God.
But this is a sacrificial meal, not a sacrifice, and this means that the initiative is the other way. God feeds us, God nourishes us, God welcomes us, God sheds His love abroad in our hearts. We do not offer this meal; He offers this meal.
Our response to this may be described as a sacrifice—but it is a sacrifice of response, specifically the response of praise and thanksgiving. This keeps the order as it ought to be. The Table is God’s gift to humanity as He makes us into His new humanity, built up into Jesus Christ, the perfect man. At this Table, we submit to His grace, and are most thankful.
I was just relating this to you table that God has set before us in the presence of our enemies. The bread or word of God, the meat or flesh that was broken for us for the healing of our flesh and iniquity, His drink or Blood he shed for our redemption.
We can eat what is at this table Or be led by what is at this table or we can let the enemy have a seat and be led by what he is giving.
