Revelation 21:15,16

15  And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.

16  And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.

The Holy City is huge! It is 12,000 furlongs or approximately  1,500 miles in length, width and height.  With this description, the Holy City either has to be a cube or a pyramid. I lean toward it being pyramid in shape and I would not discount the possibility that the Great Pyramid of Egypt was a scale model of what was once seen in heaven or described as being in heaven. The original Great Pyramid had an outer coating that reflected light. This coating has been plundered so the pyramid does not look as majestic as it once did. If this pyramid is a scale model of the Holy City, it was a model of the city before it was adorned for the Lamb’s wife.

The physical dimensions of the city itself rules out any notion that what is being described is the mystical body of Christ.  Those that hold the theology that the Holy City itself is the body of Christ seem to be saying that those who live in this city have become part of a spatial structure – something like the Borg did in the Star Trek series. The role these theologians seem to teach that we have in heaven is to be stuck in a structure for eternity playing our harps while continually praising God for sticking us in the walls. Some heaven! No wonder those stuck in the pews of such churches have little motivation to believe and trust God for salvation so they can go to the heavenly city.
