Indeed, Tom. The moment you think you're the real deal and everyone else is just pretending... that's when you can be sure you're not the real deal.

Cat, didn't Roger Morneau leave the Catholic Church precisely because he was put off by the belief that there was no salvation outside the church? You're doing the same thing by claiming you and those who believe as you do are the only Real Christians™. What hypocrisy.
I can explain it to you but I can't understand it for you.
