They come into your lives, they live near you, they're part of your families, and you may never know you just met a Catholic.
Sure they're Catholic. They go to Mass now and again. They consider themselves Catholic but they don't want to beat people over the head with their faith. They certainly don't let it interfere with their politics. Or their lives for that matter. In fact, they so mask their Catholicism that most people don't know they're Catholic. And that's how they want it. They're Catholic ninjas.
Don't be a Catholic ninja.
