Well Jesus did teach that we are to become like little children.

The gospel was for the lowly and humble common folk, not the educate philospher. It is not hard to understand. But hat puts philosophers out of work and without a pride pedastel so they need to complicate matters.

Paul warned about this kind of thing often. And today there are those who actually believe their theology is "spiritual truth" when theology is simply philosphy about God, a quite fleshly thing. The spiritual man understands this.
