Well the concept is there...and its not impossible...
In the way you describe it, it actually is impossible. Something has to give, and as it turns out, that something will include whole faiths no matter how you slice it. Many of them.
That said, there is certainly no shortage of people who made the attempt, going back at least to the biblic Paul. There is Islam, the Bahai Faith,
most esoteric groups, Unitarian Universalism, just out of the top of my mind.
couldnt we just take something that is known at 99% to be true...and build off it??
Sure, and we should. But that is not what you proposed earlier.
it doesnt nessecarily have to be a 'religion' per say...but maybe even realistic possibility...??? If it were in book form...where the reader chooses the 'base' of what is true...for example: its a fact we have souls. (Just an example...no offense to objection)...then it list all possibility of truth from serveral different 'religions' branching from that one 'fact'...and the reader can pick and choose what he/she thinks fits onto that truth...and so on and so on...like connect the dots. I guess the real question is...Is there at least ONE concept that most well-known religions have in common...and state as truth??? If so...we have a good start.
It seems to me that you are confusing religious practice with some sort of objective fact-finding. Trouble is, religion is by necessity subjective, and loses its way when it attempts to deny that.
And i personally dont think it would need to be 'recognized' for what it is...i dont like the fact we classify beliefs into groups...it seems foolish to me...
How else could you attempt to find out a common truth among them, if not by acknowledging what they teach and classifying them by those teachings?
why are we seperating things?
Because we need to tell that which works for us apart from that which does not, perhaps.
Doesnt anyone else think we should be working toward unity?? Non-seperation...i mean we are all the same really...its kind of like racism when you think about it. No?
I think you would do well to reflect a bit about the clashing needs of integration and individuality. While it is always to some degree a challenge to balance the two, it is also a basic need.
You may want to read a bit about non-dualism and Advaita as well.
