How did you tell your family that you don't believe in their religion? Did it cause a fight?
I didn't. I really didn't deem it to be all that important. And certainly not worth creating a rift within the family over.
When I came home from college, I would go to church with my parents and say all the right things in all the right places. After I graduated from college and they came to visit me, I would take them to the local church and play out the same puppet show.
Now both of my parents have passed away and I haven't stepped in to a place where organized christian religious services are held for years. I think the last time I stepped into a catholic church was over 10 years ago.
The only exception would be the buddhist temples I've visited in SE Asia as a tourist.
I don't remember exactly, I was in my late teens but I do remember she took me to our Lutheran pastor to talk some sense into me and after we spoke for a while he told her it was something I had thought through and accepted and that it was what I believe which she did not take well.
