A man does not come an inch nearer to being a heretic by being a hundred times a critic. Nor does he do so because his criticisms resemble those of critics who are also heretics. He only becomes a heretic at the precise moment when he prefers his criticism to his Catholicism. That is, at the instant of separation in which he thinks the view peculiar to himself more valuable than the creed that united him to his fellows. --GK Chesterton
