Interesting to note that postmillennial scholar Kenneth Gentry, whose commentary of Revelations should be coming out any month now, has affirmed and argue that "the synagogue of Satan" in Revelation 2:9 refers to anti-Christ Jews. He would denounce us using this for any anti-Semitism today, but that comes from his own views on race and the Jews as a race.

Also interesting also to note that majority opinion of interpreters, both premil and amil, is that "the synagogue of Satan" are Gentiles claiming to be Jews. Just a strange thing to claim!
