“And it doesn’t.”
Actually it does. I’ve seen it happen again and again. It doesn’t happen when there are anti-Catholics muddying the waters with lies, distortions, misrepresentation, false evidence, throwing in the kitchen sink, etc.
Last year I met a young man whose father was Lutheran and his mother Catholic (at least in her background). I don’t believe the mother was a practicing Catholic. The young man was raised a Lutheran. Growing up he never gave a second thought to the Catholic faith. When he started investigating the Catholic faith he did it on his own. His family wasn’t thrilled with it but they were not strongly anti-Catholic. His wife was a committed Baptist. He’s Catholic now and she’s considering becoming Catholic. She attended a Catholic Bible study class and was blown away because she learned things she never knew. When people are open minded they respond to the Catholic faith.
Now THIS I can believe!
