"Baha'is believe that the Faith has never been split into sects!"

Also, there's a little logic problem in Baha'i doctrine that has bothered me for a while. Baha'is believe that the Faith has never been split into sects (lasting ones, anyway), and will in fact remain basically undivided. But those groups that do separate from the mainstream of the Faith are declared non-Baha'is, simply because they separated. It's a semantic trick, no more. I'm sorry, but there are other Baha'i groups that do not consider the Universal House of Justice an authority. They do believe in Baha'u'llah (though not in the Covenant as we understand it, hence the term "Covenant-breakers"), so the rest of the world would consider them Baha'is. They consider themselves Baha'is too. Only mainstream Baha'is don't, and they have a powerful psychological motive for not doing so: the bedrock of their faith would be shaken if these breakaway groups were acknowledged as Baha'is.

This is very shaky ground for the claim that this faith is superior to Christianity and Islam, with respect to a lack of internal division. It also causes mainstream Baha'is to actively shun the company and opinions of certain other people who believe in Baha'u'llah; my soul tells me this is neither healthy nor just, and paradoxically, it makes the Faith less tolerant of diversity than many other religions.

And at some levels, what's really wrong with division, as long as it doesn't cause hatred or unloving behavior? I can choose to worship in a progressive church and still love conservative parishioners who leave to go someplace more suited to their beliefs. I can be an Episcopalian and still love my Unitarian and Catholic friends. (And my Muslim friends, and my Baha'i friends, and my Pagan friends, and so on!) I can even play Democrat to my Republican friends, or vice versa. It may be a little harder to understand where they're coming from, since I don't share their beliefs, but tests such as these are opportunities for intellectual and spiritual growth, not an indication that we need enforced uniformity of beliefs. I think what the world really needs is not a ban on divisions, but a spiritual discipline that prevents those divisions from causing hatred and prejudice.
