The Mercy Seat, which sits on the Ark of the Covenant, is the Throne of God, before which repentant sinners must stand to await God's forgiveness.

The rise of the 'Man of Sin', who would sit in the 'Temple of God', showing himself to be like God and exalting himself into the place of Jesus Christ on Earth.  

So how does this lead us to the fact that the Catholic Church is the 'Whore of Babylon'?

God instructed Moses to make a COPY of the original temple where God resides in Heaven.

Exodus 25: 17 - 19....'And thou shalt make a Mercy Seat of pure gold: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof.

And thou shalt make make two cherubims of gold, of beaten work shalt thou make them, in the two ends of the Mercy Seat. And make one cherubim on one end, and the other cherub on the other end: even of Mercy Seat shall ye make the cherubims on the two ends thereof'.

Recap: The Mercy Seat is the Throne of God,where the repentant stand in front of God to await His Mercy.

As we can see from the photos of Pope Benedict and Pope Francis, THEY are sitting in the Throne of God, placing themselves as God.

 Revelation 17:4 'And the woman (church) was arrayed in PURPLE and SCARLET and was adorned with GOLD and PRECIOUS STONES and PEARLS'.......And upon her forehead was written a name, a mystery. Babylon the Great, the mother of the harlots.

The harlots are the off shoots of the Roman Catholic Church, the Protestant churches.

Now look again at the photos of the bishops and the cardinals, all are adorned in purple and scarlet.......
