This video on Nichiren was a good 30 minute review. I perceive the history and doctrines of it to have developed parallel to Christianity im almost every way, and it was this eastern religious sect that practically single-handedly destroyed my faith that Christianity could be the true religion.
It has prophecies, end times, the apocalypse, hell, sectarianist violence, a "new testament" by a Charismatic leader, a "protestant reformation", fundamentalism/reinterpretation, souls, prayer to one "god" (Buddha), salvation by faith alone, pseudo-monotheism, esoteric secrets (upaya), and persecution by the government which created a persecution complex myth.
Its the ultimate challenege for any Christian who believes their religion is unique, but researches it deeply enough. I'm particularly interested in rereading the spicy scriptures on mappo (which is their version of revelation/the apocalypse,) because it reminds me of mapo tofu.
It is sad that more Christians have not even heard of Nichiren. It contains strong arguments against the uniqueness of Christianity, and since it arose in 12th century Japan there is no chance any of it could be influenced by Christianity. It is the religious equivilent to anagolous evolution in biology.
