The church in Pergamum was commended for holding fast to Christ's name even when one of their members, Antipas, was martyred for his faith. However, some in the church had embraced the teachings of Balaam, who led Israel into idolatry and sexual immorality, and the teachings of the Nicolaitans, who encouraged the same. The church was warned to repent or face judgment from Christ with his sharp, two-edged sword.
