Yep The Popes Hat has a Title on it:

Vicarius Filii Dei: which adds up to 666 also

which translates into:

VICAR OF THE SON OF GOD.

He is in place of The Son of God!

Son of God = Christ

Every Pope is Made a Substitute for Christ on Earth

So therefore Anti-Christ

Now The Term Antichrist was Used in the Bible to describe Persons also alive in the Time Of John

Simon Magus a man-witch who claimed to Be Christ Re-incarnate was The First Pope or Vicarius Filii Dei or Anti-Christ.

He is the Simon-Peter Buried in Simon Square in Vatican City.

If One wants to know about the Antichrist
The logical place to search out who that power is in The Bible The Source/Origin of That Name

Anyone who works out the Symbolism of Daniel/Revelation
Easily pins together that:

the Antichrist/Beast/Little Horn/Whore of Babylon Power Can only be the Papacy

The Biggest Clue was The Papacy thinking to change God's Holy Times and Laws

Did Obama, Justin Beiber and Prince William do That?!?
