Why Catholicism? Why now?
I became persuaded over time that Catholicism was true. I was raised Christian, but never had a super-strong attachment to any denomination, and was never baptized. When I became more interested in faith, I started out with a clean slate, and looked at the church that appealed most to me intellectually.
I respect Vance a great deal and admire his book, so this is going to take some effort for me to grapple with. It's easy to imagine someone leaving the church, but joining it? Now?
