CHAPTER I. A LABOR CHRISTIANITY A new social order is not more imperatively demanded than a new Christianity. Nothing less than this will suffice, nor will anything less be brought into being, in this crisis of transition. For while there are unchanging elements in Christianity, there are, it is equally certain, aspects that are constantly changing. The devotion to the Lord Jesus Christ, which is the central and determinative principle of Christianity, is the least variable element; the institutions and dogmas by which that devotion is expressed and seeks to act upon the world, are the most variable. Institutional Christianity is even more variable than dogmatic Christianity. It has varied greatly, is still changing, and its history shows that it is subject to the same influences as fashion the changing social order. This illuminating principle helps us to understand the past and to forecast the future of the Church. During the last twelve hundred years or more, the Christian Church and the social order in Western lands have developed on parallel lines. Each has passed through two great phases and is now entering on a third. I. The aristocratic or feudalistic phase, A.D. 700-1500. The three centuries (roughly reckoning) from, let us say, A.D. 400 to A.D. 700 were, probably, the darkest in the history of civilization--darker even than the struggle of the last five years. They were the centuries of a struggle not so colossal in its apparatus of destruction, but seeming, even more than this struggle in its darkest hours, to threaten the extinction of civilization. The Northern barbarians that had been pressing against the defences of the Roman Empire, as the yellow tides of the North Sea against the dykes of Holland, from the time of the inroads of the Cimbri and Teutons in the last decade of the second century before Christ, at last found entrance A.D. 378 when the Visigoths, who had been permitted to cross the Danube to find an asylum from the Huns, defeated the Roman armies and slew the Emperor in the great battle of Adrianople. From that year, with varying intervals of quiet, armies, or rather hordes, of men from the inexhaustible forests of Germany and Scandinavia, from the steppes of Russia and Central Asia, swept over lands for centuries accustomed to peace and weakened by bureaucratic despotism, inequitable and crippling systems of taxation, and, most debilitating of all, the essentially demoralizing influence of slavery. The mighty legions that had so long kept the frontiers inviolate vanished like a dream. The superb Roman roads and bridges fell into ruins. Fertile fields relapsed into wilderness. Towns decayed. Laws were forgotten. Cultivated languages with great literatures were replaced by barbarous jargons. It was as when a country-side is devoured by a flood, and trees are uprooted, houses and barns dissolved or swept away.
