Atheists and agnostics know more about the major religions than Catholics and Protestants.
Well, it’s not surprising when you think that so many people call themselves this or that when it’s just a habit. Their parents were Catholic, say, so they identify as Catholic. Even many of those who go to church probably don’t know much about what’s happening – just lots of bells and smells and men in fine and fancy frocks and magnificent music and rousing ritual and seductive ceremony.
I remember my brother – a professing Christian – saying to me one day that I probably knew more about his religion than he did. When he said to me, “I’m a Christian,” I wish I’d asked him, “How do you know?”
Ah, l’esprit de l’escalier, eh?
