Metaphysical meaning of synagogue (mbd)
Meta. A Jewish synagogue was a little chapel, where any one could hear the law read out of the Hebrew Scriptures; or if he was a Rabbi he could read out of the law himself. There was a constant stream of people going and coming in the synagogue, and it fitly represents the mind of man, or the phase of man's mind that is given over to religious thought. In the new birth, or regeneration, the rebuilding of your consciousness begins in this synagogue or religious mentality.
The synagogues of the Jews can also be said to represent aggregations of religious ideas based on Truth, thoughts that have not yet received the inspiration of the whole Truth. They are what might be called fixed religious states of consciousness.
The synagogue of Acts 17:1, 2, in which Paul "for three sabbath days reasoned with them from the scriptures," is the established religious thought bred in us by tradition, education, and inheritance. It is part of the very tissue of our brain cells, and holds its sway even after we have fully accepted the new revelation.
