What makes the Baha'i Faith unique?

Nothing.

Edit: This is in response to both FrediWhite & Ryan H.

If you guys ever decide to study more world religions, you would both discover that other religions, such as Cao Dai, also believe in the same thing: Uniting all the religions into one.

That is why I answered this question with "Nothing."

They resemble Unitarians in that they do not have to believe in anything supernatural, for which some claim it isn't even a true religion, but more of a spiritual movement.

They also hold that God sends us messengers from time to time, each with His latest views. Such were Moses and Jesus. Their guy came later, so by their premise his views are more correct and should be seen as replacing or modifying the older revelations. For this, of course, everybody hates them.

I attended one of their meetings some years ago and those ladies can really cook. If I had to belong to something, that would be it.

It has an apostrophe. You don't see too many of those.

This is an extremely broad question, but some of the ideas that came to mind are:

+ The Baha'i Faith is the only religion that strongly promotes the idea of Progressive Revelation, i.e. that each Manifestation of God is the same "spirit" sent down at different periods in man's history to teach (a) what is right for that age, (b) what an ever-maturing mankind can logically understand. For example, I was watching "The Last Temptation of Christ" last night and Jesus confronts the temple priests, saying He has brought new laws to Israel. The priests challenge him: Are you saying that God's laws are wrong? Jesus says (paraphrased): No, I'm saying that God thinks men's hearts are ready for more [teachings]. The Baha'is extend that concept over the entirety of religious history.

+ Furthermore, Baha'is believe that since Manifestations are essentially the same spirit presenting the same message of God (simply updated so that mankind better understands it each time), that all religions are essentially one. To that effect we recognize and validate that there are different paths to God. Though of course we want everybody to "come to God" through Baha'u'llah, our founder, we do not condemn to Hell those who are Christian or Islam or any other religion.

+ The Baha'i Faith is the only religion that predicts its own replacement. In accordance with Progressive Revelation, eventually (after at least 1000 years) a new Manifestation will appear with a new message.

+ The Faith has no clergy. It has institutions which guide and protect the religion, but they are all democratically elected. This is because the Faith, more than any other religion before it, emphasizes the independent (individual) investigation of truth; it abrogates the need for clergy to "shepherd" its members, in effect to tell them how to think. Baha'is are self-responsible in this effect.

+ It has very little in the way of formalized ritual. Even weddings and funerals have a minimum of vitalization.

+ The Faith--in very strong contrast to Christianity and Islam--strictly prohibits participation in partisan politics. Baha'is are obligated to vote and are obligated to show obedience and loyalty to their government, but for example we are not allowed to vote in primary elections (unless the victor will have no opponent in the general election).

+ Ideas that seem brand-spanking-new to the rest of the world--elimination of sexism and racism, universal voting rights, global cooperation in the elimination of poverty, world peace, etc--have been championed by the Baha'i Faith for more than 150 years.

Hopefully that's a good start for you!
