The synagogue of Satan is mentioned twice in Revelation, once in Jesus’ letter to the first-century church in Smyrna and once to the church in Philadelphia. In both cases, the synagogue of Satan is opposed to the mission and message of the church.
To the church in Smyrna, Jesus says, “I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.” Revelation 2:9
To the church of Philadelphia in Asia Minor, Jesus says, “Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.” Revelation 3:9
In short, the synagogue of Satan was a group of unbelieving Jews who were persecuting Christians. These groups were guilty of slandering the church in Smyrna and opposing the church in Philadelphia in some way.
The majority of the persecution the New Testament church faced came from the Jewish community. Even most of the Roman persecution was an effort to appease the Jewish authorities. This is true of Pilate’s condemnation of Jesus (John 19:1–16) and Paul’s imprisonment by the Roman governors Felix (Acts 24:27) and Festus (Acts 25:16). This pattern held true throughout the Roman world in the first century. As long as Christians were considered a sect of Judaism, they were exempt from the required observance of certain aspects of Roman state religion. However, as Christians were expelled from synagogues and denounced by the Jewish leadership, Rome began to see Christianity as a new religion that did not have these same exemptions. Therefore, Christians outside the protective umbrella of the synagogue were open to Roman persecution.
The synagogue of Satan say they are Jews (the people of God), and they persecute those who believe in Jesus the Messiah (the true people of God). In reality, by rejecting the Jewish Messiah, they have renounced their status as “true” Jews, and that is why Jesus calls them “liars.” This distinction between ethnic Jews and faithful Jews is also seen in Romans 9:6“Not all who are descended from Israel are Israel”
“For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.” Romans 2:28–29
By their persecution of the true people of God, these unbelieving Jews had become a synagogue of Satan—a gathering of people who were actually following the devil’s priorities.
Both churches are promised victory over the synagogue of Satan. This promise echoes Isaiah 60:14 “The sons also of them that afflicted thee shall come bending unto thee; and all they that despised thee shall bow themselves down at the soles of thy feet; and they shall call thee; The city of the Lord, The Zion of the Holy One of Israel.”
In the context of Isaiah 60, an oppressed Jerusalem will be vindicated. Those who oppress her will bow down at her feet and will have to admit that she is indeed blessed by God—in the language of Revelation 3:9—that God loves her. But Isaiah 60:14 applied to these Jews and the Church is something of a reversal. In Isaiah 60, the oppressing Gentiles will bow down at the feet of Jews and admit that God loves them. In Revelation 2—3, oppressing Jews will bow down at the feet of the persecuted Church (with a significant population of Gentiles in it) and admit that God loves them. This is a striking role reversal.
Internet searches of “synagogue of Satan” produce quite a few links to sites that claim the “synagogue of Satan” refers to the Jewish people today and that promote all kinds of conspiracy theories about how the Jews run the world. Quite frankly, this is a misinterpretation and misapplication of the verses in Revelation. The synagogue of Satan refers to specific Jewish communities in Smyrna and Philadelphia that were persecuting the church, not to any modern situation. Likewise, no modern situation should be used as an interpretive tool to explain a passage firmly rooted in the first-century Roman world.
