What is the synagogue of Satan?


I will make those who are of the synagogue of Satan, who claim to be Jews though they are not, but are liars—I will make them come and fall down at your feet and acknowledge that I have loved you. Revelation 3:9
            The synagogue of Satan doesn’t refer to all Jews, only the Jewish leadership who was used by Satan to try to stop the Christian movement in Israel.  This referred specifically to the leadership.  They weren’t really spiritually Jewish (more culturally) or they would be more open to God.
