We have another suggestion to keep from mixing Latin and Greek.
plurodoxy or polydoxy?
Which of these words do you feel immediately upon looking at them conveys to you multiple competing "orthodoxies"? Does it matter? Or do you have other suggestions for such a word?
I'm quite serious about coining such a word. I just don't think we can continue writing and talking about early Christianity without such a concept.
