With these materials it is, and others resembling these, that Christianity has carried forward the work of human progression. The ethics of Christianity it was,--new ethics and unintelligible, in a degree as yet but little understood, to the old pagan nations,--which furnished the rudder, or guidance, for a human revolution; but the mysteries of Christianity it was,--new Eleusinian shows, presenting God under a new form and aspect, presenting man under a new relation to God,--which furnished the oars and sails, the moving forces, for the advance of this revolution. It was my intention to have shown how this great idea of man's relation to God, connected with the previous idea of God, had first caused the state of _slavery_ to be regarded as an evil. Next, I proposed to show how _charitable institutions_, not one of which existed in pagan ages, hospitals, and asylums of all classes, had arisen under the same idea brooding over man from age to age. Thirdly, I should have attempted to show, that from the same mighty influence had grown up a _social_ influence of woman, which did not exist in pagan ages, and will hereafter be applied to greater purposes. But, for want of room, I confine myself to saying a few words on war, and the mode in which it will be extinguished by Christianity. WAR.--This is amongst the foremost of questions that concern human progress, and it is one which, of all great questions, (the question of slavery not excepted, nor even the question of the slave-_trade_,) has travelled forward the most rapidly into public favor. Thirty years ago, there was hardly a breath stirring against war, as the sole natural resource of national anger or national competition. Hardly did a wish rise, at intervals, in that direction, or even a protesting sigh, over the calamities of war. And if here and there a contemplative author uttered such a sigh, it was in the spirit of mere hopeless sorrow, that mourned over an evil apparently as inalienable from man as hunger, as death, as the frailty of human expectations. Cowper, about sixty years ago, had said, 'War is a game which, were their subjects wise, Kings would not play at.'
