Do the rituals define the religion?
Is it possible to have one without the other?
College football has rituals as do secular courts and schools. So it is possible to have a ritual without a religion.
But what about a religion without rituals?
I attempted to change our Temple’s rules on ritual observance to make it possible to have Temple events at my house without improvising (pretending) kosher, I lost the first attempt but expect to win in the end. Stay tuned.
