"Humanity in the past did certain things which fill us with horror. But on the other hand we are doing things now which would have filled humanity in the past with equal horror. If to us medieval intolerance causes creeps down the back, surely the tolerance of modern times, with the indifferentism inseparably bound up with it, would also have caused creeps down the back of the medieval. The notion that the existence of God, the truth of Christianity and the teaching authority of the Church should be a matter of hesitation or doubt, would have made any average medieval turn in his grave. To him these truths were as clear as the sun at noonday; so much so that any man who called them into question must be either hopelessly insane or hopelessly wicked."
