The mindset is such among world religious institutions that a truly all inclusive world savior will not manifest. The mindset is that the Islamic world savior will appear and those who do not embrace Islam will be sent to hell, removed from the planet, or possibly enslaved. He or she will have to understand the teachings of all religions but not have a preference for one over the other. He or she will have to relate to the common thread that runs through all religions and essentially speak only to these common beliefs. If he or she tried to deviate toward a mindset that was unique to one religion, he or she would alienate those who did not embrace that mindset.
Religious institutions are by their nature elitist and exclusive.
When we look at the history of religious thought world wide over time, we find that occasionally men and women with deeply rooted spiritual orientations bring their spiritual truth to a particular area of the earth and influence millions of human beings. This is an ongoing process that will never cease. What is unique in this day and time is that the world has become one and so situations of the past where a deeply rooted Western religion for the Middle East can flourish without coming into contact with an Eastern religion in India no longer exist. Buddha and Jesus were able to significantly impact their worlds without clashing with each other due to physical separation of the parts of the world they traveled. This will be tricky because to integrate the Eastern and Western religious mindsets into one mindset will not be easy.
