Yes, it would be a valid inquiry to ask where where that is stated in the Baha'i Writings. Or ask about about his reasoning that this is so. I do know that in the Kitab-i-Iqan Baha'u'llah clarifies the understanding of Muslims on certain words and doctrines, and Abdu'l-Baha does that for Christians. In the New Testament Jesus in a few places clarifies what was said in the past. The Qur'an asserts that certain understandings by the Jews and Christians are wrong, though I don't think it gives an explanation of how to arrive at the correct explanation. It seems like a reasonable assumption that They all do that. I don't know exactly where it would say that explicitly at the moment. But if there is, would you believe that as a result? Not without believing in the Baha'i authoritative sources in the first place. So where would that get you as someone who doesn't buy them as authoritative sources. There seems to be no point to asking if you are seeking the truth of the matter. What are you seeking by asking? You may not believe in any of these clarifications, though I imagine you can buy some.
Since Jesus is supposedly the Jewish Messiah, I would expect him to critique and clarify any misunderstandings the the Jews had. But right away we have the problem of the NT being written by his followers. Did they understand the things Jesus was saying correctly?
But then the NT doesn't correct things that the Baha'i Faith says were errors. Like Ishmael vs. Isaac... Satan and hell being real.... The creation story and the flood are treated as being literal. And then, there are those that say that Greek beliefs influenced some of the Christian beliefs. So, I think there is a good chance that most of the NT is in error. So, where do you start clarifying?
Not until Baha'u'llah does Satan and hell get clarified... Along with creation and the flood and several other Biblical stories. Did Muhammad say anything about those things not being literally true?
And then the Jesus story. Is it a clarification Muhammad says in the Quran that Mary gave birth to Jesus under a date palm, rather than a manger in a barn in Bethlehem? And does he clarify the stories about Jesus walking on water, or casting out demons, or having been tempted by Satan, or the resurrection of Lazarus? Pretty much all of those are clarified by Baha'is as being symbolic aren't they?
Then who knows what was really meant by Jesus not dying on the cross, but that there was a body double.
But now let's go back to these other manifestations, Adam, Noah, Abraham, Moses, Krishna, Buddha, and Zoroaster. That's where I have a problem with Tony's statement. But I actually have a problem calling any of the people from the Bible manifestations. In fact, I think there's a chance that all those stories were just legend and myth and used to build a story about a people and their God.
So, the real problem then is how do you tie in Buddha and Zoroaster as having clarified or corrected any of the misunderstood beliefs of Israelites? Then Krishna is a bigger problem. He's a character in a book. Did he write anything? But let's say is was a manifestation, then what about all the other people that those Hindus say were also "incarnations" of Vishnu just like Krishna. Why exclude them?
For me, I think that each people and culture made up their own beliefs. Made up many Gods, good Gods and evil Gods. And some had Goddesses and the Gods and Goddesses had children. Some of those stories we call myth and others we call the "Word of God."
So, I don't think it's worth even trying to tie in the Dharmic religions with the Abrahamic religions. Different people, different culture, with very different beliefs. How does any manifestation clarify those differences? Many Gods, incarnations of Gods, and reincarnation? And in the Bible all other religions weren't even considered true... But were considered false, including their Gods. I think that is how the Bible would have dealt with Hindu beliefs.
Anyway, thanks for taking up the discussion. I think Tony was just over generalizing. And if so, that's all he had to say.
