Yes to books and movies. While I would read the King James Bible, I would study my own Catholic Bibles and do attend Catholic Bible studies. Christian music is a definite yes. Nice to have rock style music with wholesome lyrics. I occasionally listen to sermons/teachings on the radio, but often find areas I question. Don’t like Joyce Meyer’s teachings much, for instance. We are all Christians and I do feel we have lots more in common, than we have differences. Of course, discussion with non-Catholics here on FR is often the pits. Lots of haters here. We Catholics seem lots more tolerant of non-Catholic Christians. Enough of my rambling. Good question.
One of my favorite Contemporary Christian songs is “Glorious Day” by Casting Crowns, straight forward theology (which btw was based itself on a protestant hymn), but I can’t see anyone that calls themselves “Christian” would ever find fault in this message.
