But the supreme attempt which so far has been made to promote unity between classes has approached the problem from a far loftier standpoint; not industrial, nor military, but religious. And this attempt has been on a larger scale and on firmer foundations than any of the others, for it has sought to unite men in spite of their differences. It has tried, that is, to get below the varieties of race or family or occupation, and create a unity which, because it transcends them all, may hope to last. As a fact this attempt has so far surpassed all others, and has met with the greatest measure of success. And lest I should be suspected of prejudice I will quote an outside witness: A very pregnant saying of T. H. Green was that during the whole development of man the command, "Thou shalt love thy neighbour as thyself" has never varied, what has varied is the answer to the question--Who is my neighbour?... The influence upon the development of civilisation of the wider conception of duty and responsibility to one's fellow-men which was introduced into the world with the spread of Christianity can hardly be overestimated. The extended conception of the answer to the question Who is my neighbour? which has resulted from the characteristic doctrines of the Christian religion--a conception transcending all the claims of family, group, state, nation, people or race and even all the interests comprised in any existing order of society--has been the most powerful evolutionary force which has ever acted on society. It has tended gradually to break up the absolutisms inherited from an older civilization and to bring into being an entirely new type of social efficiency[25]. Or to take another witness equally unprejudiced, who puts the same truth more tersely still, the late Professor Lecky. "The brief record of those three short years," referring to Christ's life, "has done more to soften and regenerate mankind than all the disquisitions of philosophers and exhortations of moralists." For a third witness we will call Mazzini. "We owe to the Church," he declared, "the idea of the unity of the human family and of the equality and emancipation of souls." That this is amply borne out by the history of the Church in early days is not difficult to prove. The unexceptionable evidence of a Pagan writer is here very much to the point. Says Lucian of the Christians: "Their original lawgiver had taught them that they were all brethren, one of another.... They become incredibly alert when anything ... affects their common interests[26]."
