I was wondering if Baha'is have any opinion about Pagan religions, since they believe most religions were once revealed by some messenger? Do they believe any of the indegionous ancient religions also were, or do any individual Baha'is have this idea, even if the faith has no official position?
Baha'is respect other religions .. regardless whether pagan, native, ancient religions, etc.
And just as the rays of the natural sun have an influence which
penetrates into the darkest and shadiest corners of the world,
giving warmth and life even to creatures that have never seen
the sun itself, so also, the outpouring of the Holy Spirit through
the Manifestation of God influences the lives of all, and inspires
receptive minds even in places and among peoples where
the name of the Prophet is quite unknown.
(Dr. J.E. Esslemont, Baha'u'llah and the New Era, p. 4)
Asiatic Prophets:
"Regarding your questions: The only reason there is not more mention of the Asiatic prophets is because their names seem to be lost in the mists of ancient history. Buddha is mentioned and Zoroaster in our scriptures -- both non-Jewish prophets or non-semitic prophets. We are taught there always have been Manifestations of God, but we do not have any record of their names."
