most americans would agree that scientology is weird. what was the impetus of its creation? like 'real' religions, both have aspects of self help built into them, as well as tidbits of philosophy regarding how to view the world and interact with it. so at what point does a philosophy become a religion? or a self help toolkit become a religion?
furthermore, at what point does a man or woman become a god? many gods, saints and other religious figures we read about as being mythical beings were actually real humans who did (presumably) admirable things in life. their followers kept talking them up for years and years, generations and generations, to the point where deification occurred and they became mythical beings in the collective consciousness.
jesus is a classic example, but consider also the ancient egyptian god of medicine, imhotep. he was an actual man who lived in the 27th century BC in egypt as a chancellor to the pharaoh, doing no doubt many kingly things, but it wasn't until 2,000 years after his death that people began equating him with a god of medicine. so basically, a following (cult?) formed around this kingly advisor, and the masses held him in such high regard that as his memory faded, they bolstered it by weaving stories of his divine healing powers: apotheosis.
then we can find more modern examples of people who might be in the process of being deified. take eugene rose (1934-1982). born in san diego, he was raised christian, then at 14 became atheist, then went to college and grad school studying asian religions and philosophies (at one point under Alan Watts), and finally at 28yo went back to christianity and entered the russian orthodox church. he established a remote monastery in the forests of northern california and wrote about heaven and creation and whatnot until he died. the interesting line is "Orthodox Christians hold him in high esteem, venerating him in iconography, liturgy and prayer [citation needed] though he has not yet been formally canonized by any Orthodox synod." so here we see a recently-deceased religious man who did some good work, and now people are including him in their prayers and paintings, but the church itself hasn't formally canonized him yet. if they do, this man is elevated towards the divine. then what happens 500 years from now? people forgot he was a mortal, and remember him only as a god.
alan watts, one of his mentors, is an interesting character unto himself. his forays into general semantics (a philosophy?) give us insight into pseudo-science (like neuro-linguistic programming) and further down the rabbit hole exploring bizarre practices like scientology.
