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.
