Yeshua rebuked those who claim to be Jews but are not Jews, and he makes reference to the "synagogue of Satan." Who are “those who say they are Jews and are not Jews” who worship in a “synagogue of Satan”? How do you know if you might not be one yourself? In this teaching, Pastor Lancaster presents an abbreviated version of his article "Synagogue of Satan," an article that appeared in Messiah Journal 113 and is to be included in the appendices of the forthcoming casebound edition of Torah Club: Chronicles of the Apostles.
I know your tribulation and your poverty (but you are rich) and the slander of those who say that they are Jews and are not, but are a synagogue of Satan. (Revelation 2:9)
Behold, I will make those of the synagogue of Satan, who say that they are Jews and are not, but lie—behold, I will make them come and bow down before your feet, and they will learn that I have loved you. (Revelation 3:9)
