I don't know much about Scientology, but I'll give another example. Sikhism is really cool, Sikhs have a lot of good principles and are like a peaceful middle ground between Islam and Hinduism. But if you're a Sikh, you're not a Baha'i. If you're a Baha'i, you're not a Sikh. It doesn't mean we can't get along, of course we can get along. Baha'u'llah said to "consort with the followers of all religions in a spirit of friendliness and fellowship." Another example... Freemasonry is a charitable organization and Masons can belong to any religion. But Baha'is are not supposed to be Masons because we're working for world unity and don't want to be labeled as something that would or could cause division. Baha'is don't join any political parties and being part of one would hinder the cause of unity. A Baha'i is a Baha'i is a Baha'i. Not something else.
