Lyric discussion by islanduniverse 

My guess is that this about Jesus Christ and his rejection of the Pharisees' version of religious life. I think the phrase, "cartoon man in the real world" refers to the fact that Jesus was not of the world he was in. "Ultra unbelievable love" refers to the supernatural level of love he was able to show mankind according to the New Testament and "nail it down" is a reference to crucifixtion.

Other lines in the song seem intended to refer to Jesus' rejection of the Pharisees' formalism: e.g., the fact that "vibat[ing] internally" is his "form of prayer" -- i.e., that his relationship with God is internal and not simply based on external routines -- and that "there are no jokes in the [Pharisees'] Bible" referring, I think, to the fact that their vision of God was far darker than that he was advocating.

This doesn't mean that the lyrics necessarily grow out of a deep faith in the New Testament (or any other set of religious tenets). But I do think that they're using the New Testament story to draw an interesting contrast between different ways of thinking about, and relating to God and to other people.
