Morgan le Fay invokes "St. Joseph"
He doesn't have a transcendent sword forged in the dawn of time. He doesn't have a wizard advisor living and surfing the collective unconscious, though he does apparently have a Morgan le Fay (see above). He doesn't have the humility to bow to the Magisterium of the holy Catholic Church (I expect him at any time to say, "How many field agents does the Pope have?") And his popularity, like Uther Pendragon's, is at an all-time low.
He is not The One. The Sword awaits the true King.
