But we have already seen what a misconception this implies of the Incarnation. The Incarnation opened heaven, for it was the revelation of the Word; but it also reconsecrated earth, for the Word was made Flesh and dwelt among us. And it is impossible to read history without feeling how profoundly the religion of the Incarnation has been a religion of humanity. The human body itself, which heathendom had so degraded, that noble minds could only view it as the enemy and prison of the soul, acquired a new meaning, exhibited new graces, shone with a new lustre in the light of the Word made Flesh; and thence, in widening circles, the family, society, the state, felt in their turn the impulse of the Christian spirit, with its touches of things common, Till they rose to touch the spheres. Literature revived; art flamed into fuller life; even science in its early days owed more than men often think, to the Christian temper and the Christian reverence for things once called common or unclean. While the optimism, the belief in the future, the atmosphere of hopefulness, which has made our progress and achievements possible, and which, when all counter currents have been allowed for, so deeply differentiates the modern from the ancient world, dates, as a fact of history, from those buoyant days of the early church, when the creed of suicide was vanquished before the creed of martyrdom, Seneca before S. Paul. It is true that secular civilization has co-operated with Christianity to produce the modern world. But secular civilization is, as we have seen, in the Christian view, nothing less than the providential correlative and counterpart of the Incarnation. For the Word did not desert the rest of His creation to become Incarnate. Natural religion, and natural morality, and the natural play of intellect have their function in the Christian as they had in the pre-Christian ages; and are still kindled by the light that lighteth every man coming into the world. And hence it is that secular thought has so often corrected and counteracted the evil of a Christianity grown professional, and false, and foul.
