The organization in which this movement was embodied, after three centuries of obscurity and oppression, rose triumphant to be the dominant power of … - Walter Rauschenbusch

It is this diffused spirit of Christianity rather than the conscious purpose of organized Christianity which has been the chief moral force in social changes. It has often taken its finest form in heretics and free-thinkers, and in non-Christian movements. The Church has often been indifferent or hostile to the effects which it had itself produced. The mother has refused to acknowledge her own children.

The Christian movement began with John the Baptist. … in his recorded teaching to the people there is not a word about the customary ritual of religion, about increased Sabbath observance, about stricter washings and sacrifices, or the ordinary exercises of piety. He spoke only of repentance, of ceasing from wrongdoing. He hailed the professional exponents of religion who came to hear him, as a brood of snakes wriggling away from the flames of the judgment. ...The way to prepare for the Messianic era and to escape the wrath of the Messiah was to institute a brotherly life and to equalize social inequalities.

We are apt... to forget that the moral force of Christianity was usually only one factor in producing such a change as the abolition of slavery or piracy, and that over against the benign influences of the Church must be set the malign and divisive influences which she created by persecuting zeal, intellectual intolerance, or religious wars. In short, we must soberly face the fact that a good many deductions have to be made from the popular panegyrics, and that the Church has not accomplished all that is often claimed for her.
