I think that there are probably more members of the Catholic Church, worldwide, than there are fan club members for John and/or the Beatles.

I mean, I like the Beatles as much as anyone, but have never signed up for any membership card.

I will grant you this: John Lennon's message has probably gotten through to more people alive today than has Jesus Christ's. I firmly believe that most of the Christian churches, most of the time throughout history, have failed to adequately present their Founder's message.
