Apparently, it’s fundamentalism.
From here:
“One of the features of fundamentalism is that you begin to believe that your apprehension of God is the right one and complete one, and consequently, all others are wrong. There are far too many unreflective fundamentalisms around in our communion today – conservative fundamentalism, liberal fundamentalism, catholic fundamentalism – all characterized by a certainly in their rightness, coupled with an intolerance of the faith perspective of others with whom they differ.”
That would make John the Baptist, St. Paul, St. Peter and the rest of the apostles all fundamentalists.
Even worse, since he claimed that his “apprehension of God” was not only “the right one” but that those who apprehended him apprehended God, it would make Jesus the definitive fundamentalist: a veritable paradigm of fundamentalism.
Jesus would have made a dreadfully intolerant Anglican – according to the Secretary General of the Anglican Communion.
