Their greatest struggle is how to incorporate all the now known knowledge and assimilate it into their dogma and theology. The problem is the impossibility of reconciling the obvious flaws in most theology and doctrine. The obvious shortcomings and how political and nationalistic and other special interests and agendas have resulted in a history filled with disappointment and tragedy. I have counseled ministers and individuals who have spent a lifetime in religious practice who have never had a Spiritual Experience in their entire life. For many it has only created confusion.

Perhaps the most brilliant early pioneer in modern psychiatry was William James, of the late 1800's. Dr. James was about a hundred years ahead of his time. No wonder that even today most people, including psychiatrists have never heard of him. God according to many, while perceived as the creator and builder of the universe and the ultimate controller of all things, is also seen as being something very distant or external. The single conscious revelation by Christ and other Masters was the realization that this is not the case.
