@siti The way I want to try to answer your question is by trying to explain my understanding of what Baha’i scriptures say, that Baha’is equate with “All religions are one.”
In the research that I did recently, I found that the idea of saying “all religions are one” goes at least as far back as 1788, and it might have been circulating in interfaith circles when the Baha’i Faith first came to Europe and North America. That might be why Baha’is started substituting “all religions are one” in the place of “essential oneness of religion” and “the reality of religion is one” from Baha’i scriptures.
My understanding of that is much different today from what it was a few days ago, and it might be much different again in a few more days. I’ll make a first try at trying to describe how I’m thinking of it now, but I hope that you’ll make comments and ask questions, to better understand it.
I’m thinking that there is a special kind of truth, spirit, power and wisdom, a kind that people sometimes call “divine” or “sacred,” in all the religious lore and scriptures that are revered by multitudes of people. I don’t think that the truth, spirit, power and wisdom in them is divided into sections that one or another of the religions can claim as its exclusive property, to vaunt itself over the others. I think that there’s a very personal and personalized relationship that we all can have with that truth, spirit, power and wisdom. That’s what I’m currently thinking now, today, that “religion,” in its singular form, means in Baha’i scriptures.
I think that the same truth, spirit, power and wisdom are in the fruits of honest and responsible scientific research, and that our personal relationship with them can be as much in that as it can in religious scriptures. I can see that in the stories of the giants of modern physics.
