Hmm. I think you misunderstand my point, which is fair given the brevity of the post. But you seem pretty content with your narrative and probably define "religion" much more narrowly than I do based on a post of yours I came across in another thread, so I think it's best that I don't elaborate.
The Merriam-Webster defines religion as follows:
1a : the state of a religious
a nun in her 20th year of religion
b(1) : the service and worship of God or the supernatural
(2) : commitment or devotion to religious faith or observance
2 : a personal set or institutionalized system of religious attitudes, beliefs, and practices
3 archaic : scrupulous conformity : CONSCIENTIOUSNESS
4 : a cause, principle, or system of beliefs held to with ardor and faith
I totally disagree with most of what it says except when it does say institutionalized. To me, religion is instituionalized while spirituality is not. If you check any source speaking of religions, they will be named. They are Christianity, Islam, Buddhism,Judaism, Hindu and others. To me, people who believe that none of these are entirely accurate due to the input of man are spiritual but not religious.That is why I call myself that.
