Christians hold themselves in high regard because they believe Jesus was the fufillment of the Old Testament predictions of a savior coming. And we all know Jesus went out of his way to fufill those prophecies too... riding a donkey and entering at the west gate etc. etc. all stuff predicted hundreds of years earlier.
Christians, in my opinion, all take the leap of faith and connect the dots to make Jesus God incarnate, which I have a hard time agreeing with.
But then again Muslims claim their own rights equally too with Mohammed as the final prophet and messenger of God.
I tend to get skeptical when the attention is taken away from God and put on someone other than God, which explains why I have no faith in the Mormons.
But overall, there's assholes in all faiths- why single out the Catholics?
