James Freeman Clarke,
Ten Great Religions: An Essay in Comparative Theology
“ It is evident that Christianity can become the universal human religion only by supplying the religious wants of all the races of men who dwell on all the face of the earth. If it can continue to give them all the truth their own religions contain, and add something more; if it can inspire them with all the moral life which their own religions communicate, and yet more; and, finally, if it can unite the races of men in one family, one kingdom of heaven,—then it is fitted to be and will become the universal religion. ”
