Sometimes I feel like a bit of a fraud. I never intended to become a public Catholic: I converted to Catholicism expecting it to fix me on the quiet. But when I saw the Church being attacked, I felt a call to defend it, and year by year I became an amateur evangelist. I do radio and TV, write columns, give speeches, and with that comes a sense of duty to accentuate the positive and win people to the cause.

I mean every word I say or write, but if I’m going to be a public Catholic I have to do so with integrity and I need to express the full truth. That means admitting that sometimes I’m angry with God. Sometimes I don’t like myself. And I suffer from doubt the way others suffer from a bad back.
