Holy cow, a dude from a 1960s hippie religion making things up, who would have thought?
Let's check the stats:
Adam Clarke:
The blasphemy of them which say they are Jews - There were persons there who professed Judaism, and had a synagogue in the place, and professed to worship the true God; but they had no genuine religion, and they served the devil rather than God. They applied a sacred name to an unholy thing: and this is one meaning of the word blasphemy in this book.
Albert Barnes:
Of them which say they are Jews - Who profess to be Jews. The idea seems to be that though they were of Jewish extraction, and professed to be Jews, they were not true Jews; they indulged in a bitterness of reproach, and a severity of language, which showed that they had not the spirit of the Jewish religion; they had nothing which became those who were under the guidance of the spirit of their own Scriptures. That would have inculcated and fostered a milder temper; and the meaning here is, that although they were of Jewish origin, they were not worthy of the name. That spirit of bitter opposition was indeed often manifested in their treatment of Christians, as it had been of the Saviour, but still it was foreign to the true nature of their religion. There were Jews in all parts of Asia Minor, and the apostles often encountered them in their journeyings, but it would seem that there was something which had particularly embittered those of Smyrna against Christianity. What this was is now unknown.
It may throw some light on the passage, however, to remark that at a somewhat later period - in the time of the martyrdom of Polycarp - the Jews of Smyrna were among the most bitter of the enemies of Christians, and among the most violent in demanding the death of Polycarp. Eusebius (Eccl. Hist. 4:15) says,. that when Polycarp was apprehended, and brought before the proconsul at Smyrna, the Jews were the most furious of all in demanding his condemnation. When the mob, after his condemnation to death, set about gathering fuel to burn him, “the Jews,” says he, “being especially zealous, as was their custom - μάλιστα προθύμως, ὡς ἔθος αὐτοῖς malista prothumōs, hōs ethos autois - ran to procure fuel.” And when, as the burning failed, the martyr was transfixed with weapons, the Jews urged and besought the magistrate that his body might not be given up to Christians. Possibly at the time when this epistle was directed to be sent to Smyrna, there were Jews there who manifested the same spirit which those of their countrymen did afterward, who urged on the death of Polycarp.
But are the synagogue of Satan - Deserve rather to be called the synagogue of Satan. The synagogue was a Jewish place of worship (compare the notes on
Mat 4:23), but the word originally denoted “the assembly” or “the congregation.” The meaning here is plain, that though they worshipped in a synagogue, and professed to be the worshippers of God, yet they were not worthy of the name, and deserved rather to be regarded as in the service of Satan. “Satan” is the word that is properly applied to the great evil spirit, elsewhere called the devil. See the
Luk 22:3 note, and
Job 1:6 note.
Matthew Henry: 3. He knows the wickedness and the falsehood of their enemies:
I know the blasphemy of those that say they are Jews, but are not; that is, of those who pretend to be the only peculiar covenant-people of God, as the Jews boasted themselves to be, even after God had rejected them; or of those who would be setting up the Jewish rites and ceremonies, which were now not only antiquated, but abrogated; these may say that they only are the church of God in the world, when indeed
they are the synagogue of Satan.
