These men received communication from God, ushered in a new religious cycle and established a true religion.
Which included Abraham and Krishna, So I ask...
What religious cycle and which true religion did Abraham and Krishna usher and establish? ...This is your Baha'i claim.
We are in the cycle which began with Adam, and its supreme Manifestation is Bahá’u’lláh.
There is so little reason to believe Adam was a real person, let alone a manifestation. Yet, Baha'is make a whole cycle about him? Is the creation story real or metaphorical? Was Adam real or metaphorical? Then we move on...
Abraham is associated with Judaism, Krishna with Hinduism. That is all I know.
From Adam we eventually get to Noah. Was there a flood? Did Noah live to be 950 years old? True or metaphorical? Or, like I believe, mythological?
Then we get to Abraham. He supposedly heard God's voice and that voice told him to go kill his son. Did God really say that? Like you, I think all this in Genesis are just fictional stories. These are the stories about the Israelite people. It is their myths about creation and about how they came to be in the land of Canaan. Why does he have to be real? Why does he have to be a manifestation? And, if he is a manifestation, like Baha'is claim, then what religion did he establish? I don't think he established anything. The story is ongoing. If Abraham is a manifestation, then why not Noah, Melchizedek, Jacob, Isaac, or Joseph? They were all part of the same story leading up to Moses and the Exodus and, finally, to the Children of Israel conquering the Promised Land.
Then there's Krishna. People in India had lots of religious beliefs before there was a Krishna. Again, real or myth? Was the story about Krishna accurate? Actually, Baha'is have already made it clear that the Scriptures of all the early religions have been corrupted. But the story about Krishna is real? I doubt that is what Baha'is believe, but they believe in Krishna. Baha'is make Krishna real and a manifestation but reject what the Hindu sect that believes in him says about him.
Do Baha'is believe in the Scriptures that talk about the life of Krishna? No. Do they believe in the sects of Hinduism that believe in Krishna? No. There is no reason why a Baha'i needs to believe anything about any sect of Hinduism except, for the Baha'i, it was one of the "revealed" religions by the one true God and Krishna was his manifestation. But Krishna was the 8th Avatar. Why don't Baha'is believe and talk about the previous seven Avatars? Because they don't need them. They don't believe in them. And, I wouldn't be surprised, if Baha'is called those other Avatars mythical.
You don't care. You don't know. You don't want to know. You're happy knowing only what the Baha'i Faith says. Fine, but Baha'i keep saying things that ties in these other people and the other religions. What Baha'is say needs some clarification and some support for their claims. And it is usually "zero". And, in some cases it's a minus number, because the answer is worse than if there were no answer. If Baha'u'llah is the return of all the promised ones of all religions, there should be substantial support for his claims.
The religion true for you, that's just great. But then Baha'is say things that sure sound like claims. And people are going to challenge those claims. But even if you only call them "beliefs", they're still worded in a way that those 'beliefs" are going to be challenged.
