Seeing the body as the Temple alters part of the misperception, but not all of it. It DOES recognize, however, that the concept of addition or subtraction in PHYSICAL terms is not appropriate.But the next step is to realize that a Temple is not a building at all. Its REAL holiness lies in the INNER altar, around which the building is built. The inappropriate emphasis which men have put on beautiful Church BUILDINGS is a sign of their own fear of Atonement, and unwillingness to reach the altar itself. The REAL beauty of the Temple cannot be seen with the physical eye. The spiritual eye, on the other hand, cannot see the building at all, but it perceives the altar within with perfect clarity. This is because the spiritual eye has perfect vision.
For perfect effectiveness, the chalice of the Atonement belongs at the center of the inner altar, where it undoes the Separation, and restores the wholeness of the Spirit.
Before the Separation, the mind was invulnerable to fear, because fear did not exist. Both the Separation and the fear were MISCREATIONS of the mind, which have to be undone. This is what the Bible means by the “Restoration of the Temple.” It DOES NOT mean the restoration of the building, but it DOES mean the opening of the altar to receive the Atonement.
This heals the Separation, and places within man the one defense against all Separation‐mind errors which can make him perfectly invulnerable.
