What a great question! I've been lurking in this discussion. My own answer is...I read whatever interests me.
This question reminded me of an incident that occurred when we first moved where I live now and joined the church in town. The Pastor came to visit us, and he noticed my book shelves. He pointed out my John Updike collection. I blushed, then he said, Oh, I like to read him, too. We had a good laugh and then discussed our favorite authors.
My Uncle was a Lutheran pastor as well, but I never recalled him reading anything except Christian related materials. Perhaps he just didn't have the time for anything else.
We almost sent our kids to a Christian school. At the time, we lived in a city, and the schools weren't safe. We ended up not sending the kids to a Christian school, and I homeschooled until we could move to an area where the public schools were safer. I'm upset about the book banning that is going on in schools. I also observed that in the Christian schools, most of the classics I had read in school would not be taught at all because of their secular themes. For me, literature is history.
I hope I wasn't out of line in my response.
