The "7 heads" of the composite beast that speak blasphemies are the false & corrupted religious systems of the world - Atheism, Heathenism, Judaism, Eastern Mysticism, Islam, Catholicism, and Protestantism, the "ten horns" are political. In Revelation 12:3 the seven diadems (crowns of authority) rested on the seven heads, but in this prophecy the diadems rest on the ten horns. This transition means there is a change in persecuting authority. The seven heads represent the church side of Babylon and the ten horns represent the state side of Babylon. The composite beast will function as a global church state. The "dragon" http://bible.cc/revelation/20-2.htm , gives this government-beast its power, its throne, and great authority and they worship him by obeying him http://bible.cc/romans/6-16.htm .
