Although Koontz was born into the United Church of Christ, he converted to Catholicism after marrying his wife, Gerda. When I started dating Gerda, we didn't have much money. We would go on Sundays to neighboring Jonestown, where she had aunts and uncles. I was so impressed with the sense of family among them and the fun they had being together and the easiness with which they interacted that I, either rightly or wrongly, identified that in my mind as being a consequence of Catholicism, which was so strong for all of them. So, it got me interested in it. When I was in college, I expanded my reading about things and ended up thinking about halfway through college that this was for me.
