The question was posed: Are you a religious or spiritual person? What is the difference?

For me:
"Religious" means you belong to a particular religion/denomination/etc. "I'm religious" is a generic way of saying, I'm catholic, baptist, methodist, mormon or anything else. That person may, or may not, have any kind of spirituality.

"Spiritual" is about the relationship you have to the higher power/fellow humans/earth/etc. It does not require a church, a group, or anything else along those lines.

I'm spiritual but not religious.
