You got me thinking and remembering, and I feel urged to write.
The only reason I left my chosen church - the only one I had had my entire adult life and otherwise loved very much - was because slowly, surely, almost insidiously, and for no obvious reason that I can discern, I came to my own realization that any church that says it has The Corner On The Market Of Truth.... doesn't.
The One Book thing divides we humans from believers of "Other Books".
The One Book thing divides we humans from believers of Non-Book beliefs.
Hell, (heh, sorry) the members of any singular One Book cannot even get their shit together and decide how their chosen Book is to be obeyed, celebrated, lived-out in life, take your pick. Judaism is split, Christianity is split, and Islam is split - fact.
This is not a pitch for the UU, but the only reason I chose to go there was because the members have sooo many different back-stories, present-day beliefs and hopes for the future, and they didn't basically care what I have in my head (other than a desire to see me live peacefully while at church) that it seemed a good respite from being at a One Book AND Only THIS Church place - much as I think that they still have an incredible amount to offer.
God is supposed to be All-Knowing, All-Seeing, All-Present, All-EVERYTHING... and I got to the point where I simply couldn't see any more how this Creator could make it so the one-and-only-one ticket to Heaven / Paradise was through just this oooone Book and this ooooone Church and only if you do theeeeeese very specific ordinances (ceremonies, for ex. baptism) and even then, they don't count unless they are done with the assistance of only thiiiiiiiiiiis particular class of authorized person AND following thaaaaaaaat particular set of guidelines. So I have concluded that God is simply bigger than that and our understanding is pretty flawed aka very narrow.
I am done with thinking that anyone Non-Whatever-I-Am is Wrong or Bad or Damned-to-Hell or Influenced By The Devil.
So - I listen to everybody, now. I haven't read Rumi yet - he wasn't on my former church's approved reading list. But now I will look him up. I have heard that the poetry is beautiful, and I will see for myself.
