|The Perfect Square: Saint Peter's Square|
The Perfect Square is Saint Peter's Square - a square made up of two squares. The first square is the Pentecostal Church and the second square is the Catholic Church.
The Holy City is a single square relocated, at 45 degrees, from Old Jerusalem to the Vatican City such that the two squares constitute the eight-sided Saint Peter's Square or the Octagon called Dome of the Rock.
Therefore the Vatican City, symbolised by Saint Peter's Square, is the New Holy City (the New Jerusalem) described as follows;
The city was perfectly square, as wide as it was long. (Revelation 21:16) "GNT"
The City = Vatican City
Perfect Square (perfectly square) = Saint Peter's Square
As wide as it was long: Square
A perfect square is a square made up of the four squares the prophet Ezekiel described as Four Living Creatures.
Also out of the midst thereof came the likeness of four living creatures. And this was their appearance; they had the likeness of a man. (Ezekiel 1:5) "KJV"
Four living Creatures = Four Squares (Perfect Square)
A Living Creature = A Square
They had the likeness of a man: each square looked like a human being because it was made up of the Christians. It is called a Living Creature because the Christians are the ones called the living.
The four squares constituting the perfect square are four compartments of a UFO (a spacecraft) which has been transporting God's people from the past to the future of the world. The prophet Ezekiel saw the spacecraft (the UFO) and the hands of the passengers (the Christians.
And they had the hands of a man under their wings on their four sides" (Ezekiel 1:8) "KJV"
The spacecraft is light, and the passengers are the people of god. As Christ (the light) advanced from the past to the future of the world, so the people of God travelled with him.
Christ is the time-traveller, travelling across the universe; through him, mankind is able to travel in light years from the past to distant future.
Since Saint Peter's Square is the Perfect Square (the foursquare), Saint Peter's Square is the Cross.
