When we come here to partake of the body and blood of the Lord, we use that language—because Scripture does. But at the same time, we want to guard against a crass literalism that throws out something else that the Bible teaches with equal clarity.
Christ assumed a human body, and He did so forever. The Incarnation was not a temporary adoption of a “man suit,” but rather it was the stupendous miracle by which the second Person of the Godhead joined Himself to our human nature forever. This human body was not swallowed up by Christ’s divinity, but rather was joined to the divinity in the one Person of Savior and Lord, Jesus of Nazareth.
This is one Person, and two natures. These two natures are joined in the miracle of the Incarnation—which we are preparing to celebrate again in the coming Advent season—and they are joined without confusion or muddle. The attributes of one nature do not alter the nature of the other, and yet this happens without making Jesus the ultimate schizophrenic.
But what does this mean at this Supper? It means that Christ’s physical body is no more resting on this Table physically than your body is in China right now. A true human body, which Christ has, has defined limits. That’s the way bodies are. So how do we partake of Christ’s body? We do so through the power of the Holy Spirit, who weaves us into the Head by this sacramental means. Come then, and welcome to this glorious union.
