But you seem to have a love/hate relationship with Baha'i
I think they could be right, or they could be wrong. I don't agree with their concept of progressive revelation, because it depends on there having been an "original" message from the prophet/manifestation, that later got changed by his followers. And there is one important change that is claimed by the Baha'is... That Ishmael was swapped with Isaac in the story of Abraham taking his son to be sacrificed. I've asked Baha'is, when did this change happen? If all the copies of the story have Isaac. And those copies pre-date Islam and the Baha'i Faith, then what was the scribes' motive to make the change?
Then there is the supposed "fulfilled" prophecies. All of them are problematic. The best they have is that the year 1260 in the Islamic calendar is 1844. Trouble is... six different things, that all begin and end at different times, are made to start with the Hegira in 621AD and end in 1844. So, why would prophecies in Revelation have anything to do with Muhammad and the Hegira? Because Baha'is make it about Muhammad. And then they make about The Bab and Baha'u'llah. Which brings me to what I think is the worst "fulfilled" prophecy, the "Three Woes". They say the first "Woe" was Muhammad. The second, The Bab. And the third Baha'u'llah. In context, the "Woes" seem to be bad things, judgements by God that are all part of the tribulation period leading up to the return of Christ.
If none of that matters, and all religions have been corrupted by people and things added in, then the Baha'i Faith has some good things. It's time for all people to learn to live as one. But, ultimately, living as one includes living under Baha'i laws. None of the religions with a lot of "Divine" laws seems to have worked out so well. Even super-strict Christian sects, that put people in stocks, marked them as sinners, or even burned them at the stake didn't get their people to obey. So, if those things don't work. And if stoning them to death didn't work. Then what will Baha'is use to enforce "God's" laws that will be any better?
So, is the Baha'i Faith true? I don't know for sure, but I doubt it. I can't see that the Promised One has come more than 150 years ago and the world is still going through the tribulations. And that is what I ask. Does Christ return before or after the tribulations? Does he come and fix things? Or does he come and die, and leaves the world still in turmoil, but leaves them a plan on how to fix things?
