The Holy Spirit and the Lord's Supper

The Lord's Supper is one of those delivery mechanisms by which the Holy Spirit sustains our union and communion with Christ. We don't have to figure out how Christ is either absent, swingly, or present Luther on earth at the altar or table here on earth. Because it's the Holy Spirit who unites us to Christ. But he says this idea of ubiquitous flesh or humanity that can be in multiple locations is a monstrous phantasm.
