On the point of Christianity lacking true spirituality, the search for the Divine within us, Paul may have got it right and understood, but did the Church actually follow his ideas? There are different levels of Christianity, which in simple terms could be called exoteric and esoteric. It's the exoteric level I was referring to in the article. Paul actually made this distinction himself, saying that his teachings were for the spiritual (esoteric) level followers. Others following him were not ready for such teaching, so he said.

It's also worth noting that Paul himself was considered a Gnostic at the time. For example, the Gnostic teacher Marcion considered him the one true apostle. In modern times the distinguished scholar Elaine Pagels has written The Gnostic Paul.

Christianity may well declare “that those who trust in Jesus as their saviour have Christ, the Son of God, living within them”. But how many conventional (exoteric) Christians have actually found him? Jung offers a way of finding. He is not diametrically opposed to Christ and Christianity, he is seeking to heal it from its misunderstandings.
