Satan, Synagogue of
The Phrase in Revelation
The expression "synagogue of Satan" appears only twice in the entire Bible, both times in the book of Revelation. In his message to the church at Smyrna, Jesus says: "I know the slander of those who say they are Jews and are not, but are a synagogue of Satan" (Revelation 2:9). A nearly identical statement is made to the church at Philadelphia: "I will make those of the synagogue of Satan who say that they are Jews and are not, but lie — I will make them come and bow down before your feet" (Revelation 3:9). In both cases, Jesus addresses communities of believers who are facing opposition from people who claim Jewish identity but whose actions align them with the adversary rather than with God.
Who Were These People?
Three key observations emerge from the text about those who constituted the "synagogue of Satan" in Smyrna and Philadelphia. First, they claimed to be Jews — they were descendants of Abraham and asserted their right to the covenant promises made to Israel. Second, their claim is rejected by Jesus, who declares they are not truly Jews in the spiritual sense. This echoes Paul's argument in Romans 2:28-29 that a true Jew is one who is circumcised in heart, not merely in the flesh. Third, they were active persecutors of Christians. Jesus acknowledges their "blasphemy" — their hostile denunciations of Christ and his followers. Rather than being God's assembly, they functioned as Satan's assembly, serving the enemy's purposes through their opposition to the gospel.
Old Testament Background
While the exact phrase "synagogue of Satan" does not appear in the Old Testament, several passages convey a similar concept. In Numbers 14:27, 35, God speaks of "the evil congregation" that he threatens to consume in the wilderness for their rebellion. Psalm 22:16 describes "a company of evildoers" encircling the psalmist. These passages establish a biblical pattern in which assemblies that claim to represent God may actually oppose his purposes. The concept of a corrupted religious assembly that works against God's will was therefore not entirely new to the early Christians who heard John's Revelation.
Historical Context: Jewish-Christian Tensions
The tensions described in Revelation reflect the historical reality of the late first century, when synagogues in cities like Smyrna and Philadelphia were centers of opposition to the growing Christian movement. This hostility continued well beyond the writing of Revelation. Around 155 AD, when the bishop Polycarp was martyred in Smyrna — the same city addressed in Revelation 2:9 — the Jewish community there was conspicuous in demanding and supporting his execution. An ancient inscription from Smyrna references a group described as "those who were formerly Jews," which some scholars interpret as Jews who had lost their distinct legal standing as a separate community. This historical evidence confirms that the religious tensions described in Revelation were real and ongoing.
Theological Significance
The "synagogue of Satan" passages raise a profound theological question: what defines the true people of God? Jesus' words make clear that ethnic descent or religious labels alone do not make one part of God's community. True membership in God's people is defined by faithfulness, love, and allegiance to Christ. The phrase serves as a warning that religious institutions and identities can be co-opted for purposes directly opposed to God's kingdom. Satan's strategy, as depicted here, is not merely open atheism but the corruption of religion itself — using outwardly sacred structures to persecute genuine believers.
A Message of Encouragement
For the original recipients of these letters, the designation "synagogue of Satan" was deeply encouraging. The churches at Smyrna and Philadelphia were small, persecuted communities facing powerful opposition. Jesus' words assured them that he saw through the pretensions of their opponents. The promise to Philadelphia that their persecutors would eventually "come and bow down before your feet" (Revelation 3:9) echoes Old Testament prophecies about the nations recognizing God's people (Isaiah 60:14). These believers could endure their present suffering knowing that Christ himself validated their faith and condemned their oppressors.
Biblical Context
The phrase 'synagogue of Satan' appears exclusively in Revelation 2:9 and 3:9, within Jesus' letters to the seven churches of Asia Minor. The Smyrna letter warns of coming persecution and encourages faithfulness unto death (Revelation 2:10). The Philadelphia letter promises vindication and an open door of mission. The concept connects to Paul's teaching in Romans 2:28-29 about true versus outward Judaism, and to Old Testament passages about evil congregations (Numbers 14:27, 35; Psalm 22:16).
Theological Significance
This expression teaches that outward religious identity does not guarantee genuine relationship with God. Jesus defines true belonging to God's people not by ethnicity or institutional membership but by faithfulness and truth. The passages also reveal Satan's strategy of corrupting religious institutions to oppose God's purposes. For persecuted believers, the designation offers assurance that Christ sees the truth behind false claims of spiritual authority and will ultimately vindicate his faithful ones.
Historical Background
In the late first century, Jewish communities in cities like Smyrna and Philadelphia were centers of opposition to early Christians. This hostility is well attested historically. Around 155 AD, the martyrdom of Polycarp in Smyrna involved active Jewish participation in demanding his execution, continuing the pattern described in Revelation. Ancient inscriptions from Smyrna reference 'those who were formerly Jews,' reflecting the complex religious landscape of the region. Sir William Ramsay's studies of the seven churches provide valuable archaeological and historical context for understanding these tensions.
