Humility, again, is said both by its upholders and opponents to be the peculiar growth of Christianity. The real and obvious reason of this is often missed. The pagans insisted upon self assertion because it was the essence of their creed that the gods, though strong and just, were mystic, capricious, and even indifferent. But the essence of Christianity was in a literal sense the New Testament-a covenant with God which opened to men a clear deliverance. They thought themselves secure; they claimed palaces of pearl and silver under the oath and seal of the Omnipotent; they believed themselves rich with an irrevocable benediction which set them above the stars; and immediately they discovered humility. It was only another example of the same immutable paradox. It is always the secure who are humble.
