Great information above! Thank you!
“I’m spiritual but not religious,” is a very open statement, meaning that spiritual could be believing in Jesus, having faith, and praying, and not wanting to go to Mass or church of any kind or it could mean the person follows Buddhism. I follow the thoughts above in probing into how the person defines spiritual and religious, and to what their history is that led to their current beliefs. A friendly, respectful dialogue with options for follow-up seems like a great path for starters.
