Age postponed it to another life, Christ had already taught the truth, which alone can turn either of these hopes into something more than the expression of an egoistic desire--the truth that "the kingdom of God is within us." The reaction of the social necessities of mediæval society on the doctrine--which Comte quite correctly describes as leading to the gradual elevation of humanity and of human interests--found its main support in the principles of the doctrine itself, so soon as its lessons had been absorbed into the mind of the people. The irresistible force of the movement, whereby the intelligence was emancipated from authority, and the claims of the family and the State were asserted against the Church, lay above all in this, that Christianity itself was felt to involve the consecration of human life in all its interests and relations. Luther's appeal to the New Testament and to the earliest ages of Christianity was in some ways unhistorical, but it expressed a truth. Protestantism was not a return to the Christianity of the first century; it was an assertion of the relation of the individual to God, which was itself made possible only by the long work of Latin Catholicism. But the development of a doctrine, if it has in it any germ of truth which is capable of development, involves a continual recurrence to its first, and therefore its most general, expression. The elements successively developed in the Catholic and the Protestant, the Latin and the Germanic forms of Christianity, were both present in the original germ, and the exaggerated prominence given in the former to the _negative_ side of Christianity could not but lead, in the development of thought, to a similarly exaggerated manifestation of its _positive_ side. But it is nearly as absurd to say, as Comte does, that the true logical outcome of Christianity is to be found in the "life of the hermits of the Thebaid," as it would be to say that its true logical outcome is to be found in those vehement assertions of nature--naked and unashamed--as its own sufficient warrant, which poured almost with the force of inspiration from the lips of Diderot. Both extremes are equally removed from that special moral temper and tone of feeling which we can alone call Christian--the former by its want of sympathy and tenderness, no less than the latter by its want of purity and self-command. Reassertion of nature through its negation, or to put it more simply, the purification of the natural desires by the renunciation of their immediate gratification, is the idea that is more or less definitely present in all phases of the history of Christianity; and, though swaying from one side to the other, the religious life of modern times has never ceased to present both aspects. Even a St. Augustine recoiled from the Manichæism by which nature was regarded, not simply as fallen from its original idea, but as essentially impure. And, on the other hand, even
