The Woman Clothed with the Sun of Revelation 12 symbolized God's people, Israel in the Old Testament and the Christian Church in the New Testament. Satan, symbolized by a dragon, persecuted the woman during the 1260 years of the Middle Ages but God protected a remnant who were faithful to Him.
In Revelation 14 the 144,000 are first pictured triumphant with Jesus “the Lamb” and then their Message to the World is given. The “First Angel's Message” announces that the “Hour of His Judgment has come”, the Second that “Babylon is fallen” and the Third Angel's Message warns against the Mark of the Beast and presents those who keep the commandments of God and the Faith of Jesus.
The church of Pergamos is the third of seven prophetic messages to the Christian Church. During the Pergamos era the union of church and state compromised the purity and mission Jesus had given His followers.
