He fails miserably. Newman's greatest problem is that he generalizes with wild abandon, and his accuracy is compromised for it. The problem is that Newman implies constantly that such disagreement is a grievous error in judgment, that Mem Church stands as a pillar of truth despite its lax theology, and that all who depart from it are surely misguided. He apparently fails to question the rationality of those who depart from the doctrine made perfectly clear by the Bible in favor of picking and choosing truths as they please. Furthermore, Newman equates ardent faith by definition with religious zealotry, as if those who believe deeply are in fact deluded.
