The immovable ladder.
The immovable ladder is one of the most bizarre things to come out of the Christain religion. It exists because of a stalemate between the Catholic and Orthodox churches that control the site of Jesus Christ's death and resurrection. This video explains the history of the immovable ladder really well. It is a Mason's ladder strangely enough.
The Immovable Ladder exists in the place where Jesus was resurrected and the ladder is a good metaphor for something that gains access to a higher level. Resurrection gains access to the higher world and in this place, it is higher than the religions of the world and it cannot be moved. It is always there for anyone to access if they want, but they have to rise above the flaws of the world.
As stated on the Reinterpreting the Bible page, the place where Jesus died and was resurrected has a lot of symbolic value and the story represents the death and resurrection that goes on in the mind itself. Once someone has been resurrected, they will gain access to a higher level of awareness.
Matthew 27:33, "They came to a place called Golgotha (which means “the place of the skull")
The cross that Jesus Christ died on represents the four elements, the four cardinal directions, the four seasons etc. Jesus Christ being nailed to the cross means that his soul was bound to the physical world and his resurrection came after his death. The name of the hill that Jesus Christ was crucified on is called Golgotha, which means skull, could that be any more of an obvious metaphor for the soul being "crucified" while it is in the body.
27:51, "At that moment the curtain of the temple was torn in two from top to bottom. The earth shook, the rocks split 52and the tombs broke open. The bodies of many holy people who had died were raised to life. 53They came out of the tombs after Jesus’ resurrection and went into the holy city and appeared to many people."
The temple is a metaphor for the body and the veil that covers the holy of holies from the rest of the temple is the soul. When Jesus died, that veil was torn and his spirit was released. It's interesting that after the veil was torn, then the tombs were opened and other holy people were released from death. As mentioned on this page, death had a different meaning in Jesus' time and it represented the ignorance of the soul and the place it came from.
Jacob's Ladder is a popular symbol within Freemasonry and it is associated with the other major symbols of Freemasonry as well. In this picture there is a key hanging off the ladder and the key represents something that accesses the higher realms. The Vatican is laid out in the shape of a giant keyhole and in the Decoding Metallica page, in the song The Unforgiven, the boy hides a key within himself before he enters the symbolic body and doesn't take it out until he is at the end of his life.
Genesis 28:10 "Jacob left Beersheba and set out for Harran. 11 When he reached a certain place, he stopped for the night because the sun had set. Taking one of the stones there, he put it under his head and lay down to sleep. 12 He had a dream in which he saw a stairway resting on the earth, with its top reaching to heaven, and the angels of God were ascending and descending on it."
