A problem arises in that the Ark, although designed by God and instruction given from, was built by man. Mary was not built by man, unless we are to suggest that Mary’s parents were the builders, but they lack direct instruction. God came upon the tent and filled the tabernacle, Moses could not enter the tent = God came upon Mary, filled her womb, Moses/Joseph/anyone else… could not enter her?
Surely the ten commandments would be more accurately the word of Jesus, written down on tablet therefore the written gospels, Moses therefore the gospel authors, as opposed to Jesus the man. Or is Jesus the stone tablet placed in the wooden ark? The commandments where also given before the ark’s construction; Jesus was given after Mary’s ‘construction’.
I see where you are coming from, and some good ideas, but there are some basic problems arising, with regards to continuity and finer points.
