Why am I an atheist? Such a question would have seemed ludicrous to me just a few short years ago. And if you told me that it was the deepening of a religious belief that led me to such a position, I would have been completely baffled. But that is, in fact, what happened. Allow me to explain.

That all changed when we moved across states and into my grandmother’s house. Immediately, I was enrolled in catechism classes, and the indoctrination began in earnest. I discovered that I had been baptised as a baby. I was forced to pray the Rosary with my family in front of the Marian shrine my grandmother had built. Attendance at Mass became mandatory. I was brought to Confession, and forced to tell these strange men what I thought I had done wrong that week. I argued with my father that I didn’t believe in a god, so I shouldn’t be forced to do this. His only reply was that until I could disprove the existence of god, I was going to go. During this time, my otherwise moderate mother, raised a Baptist, became a Catholic. My younger sister was also baptised and forced to participate.

This went on for several years. My faith was only deepening, and I was beginning to think that I was being called to a life of ministry. I watched 9/11 happen, and my faith was unshaken.
I was proud of the fact that MY beliefs were grounded in rational thought, not like those other religious people. I integrated myself into the local Catholic church, and was on my way to a typical unthinking lifelong acceptance of Catholic dogma. Ironically enough, the thing that made me reevaluate my beliefs was my father’s deepening religious feelings.

The problem was that neither side stood up to the scutiny. When I subjected both to the same level of proof that I demanded of other truth claims, and especially other religious claims, they both withered. I was devastated. I spent many hours wrestling with this problem alone. Then, I told my wife of my doubts. Finally, I admitted to my father that I was no longer a believer. This has been a constant source of discord between us, but it can’t be helped. My wife and children were all too happy to shed their religious personas, and we quickly became a happy little secular household.
