JeffT: Scientology yes, Mormonism no, depending on what time frame you use. The Mormons predate the Watchtower.
I was thinking about the origins of the Abrahamic religions, which would have been many centuries prior. Mormonism was born during a period of upheaval in the US, but most of the denominations that grew out of it based their beliefs on the Bible. Joseph Smith decided to write a new book and effectively create a new religion. Hubbard decided to do him one better. It remains amazing to me that either survived the religious environment of their time (and, in fairness, Smith himself did not survive it).
