Who is Jesus from A Coney Island of the Mind, Poems and what is their importance?

Jesus shows up real late, a carpenter from Galilee, claiming that he is the son of God who made heaven and earth. The proof is on the parchments which are around the Dead Sea which will not be found until 1947. No one believes him so they stretch them on a Tree where he hangs but does not come down. He is used as a model. Jesus climbs down from the bare tree and runs away from the materialist Christmas. He steals softly into an anonymous Mary's womb to await the Immaculate Reconception and the Second Coming.
