You are correct on much, but the word religion is not found in the King James version of the Bible.
Think about that.
I think we are stuck in somantics. I have not been to church in 25 years. Religion, like any tradition is built up over time, often on the shoulders of giants.
Many things "traditional" are made up of plenty of "roughage" that is good for the soul. Like the food of today, watch out you are not consuming some VERY white bread fast food.
