That's why I'm questioning it. To me, it could very well be a made-up belief to tie in the different religions with the Baha'i concept of progressive revelation. But... if the concept is real and is the why the one true God did things, why not make it clear... "This man is a manifestation. He is bringing you the truth about me, the one true God." And then say, "These other guys are prophets. They aren't the same as a manifestation." And then make it clear how each is defined.
So how did Jesus fair when he gave a Message, that veiled his true station. What about Muhammad, the Bab and Baha'u'llah?
Mankind is still very immature when it comes to embracing our spiritual selves.
If we do not embrace the concept now, what makes one think they would have 2000 years ago?
Yet the Station of a Manifestation shows us how the Christians could see Jesus as God. It explains the error of the Trinity, which Muhammed in the 600's already told the Christians not to purse as the trinity doctrine. It has just become a great veil.
