Human beings worship stories. That's the message of religion. They don't worship ideas. They don't worship reason. They don't worship the Truth. The Gospels are a narrative. They are not philosophy, science, mathematics or theology. That's why the smartest people don't take Abrahamism seriously. You might as well proclaim the Lord of the Rings as the revelation of God. If it were 2,000 years old and covered in "holy" dust, we might well be saying prayers to Gandalf, Aragorn and Frodo Baggins each Sunday.
Heretic is a Greek word meaning "one who chooses" i.e. one who thinks for himself. The corollary is that the orthodox are those who do not choose i.e. they take what they are given. They obey orders. They never think for themselves.
