The denominations of Judaism differ from each other, in non-signifigant, non-trivial ways. There are serious disputes on philosophical and practical levels. What does “non-denominational” actually mean? Can you have Judiasm minus denominations?
To clarify, I’m not asking about what would Judiasm be like without denominations. I’m asking about, in the context of our denominations, having a “non-denominational” “Jewish” space.
