"Thus it is that religious sentiment becomes the measure of religious truth. It receives all in religion that addresses itself to the soul, all that nourishes and fortifies the soul, all that raises the soul to the infinite and the ideal, all that unites the soul to God. {257} Religious sentiment appropriates it all, but it appropriates nothing more. Let but a thing become indifferent, and it feels it as an importunity, and looks upon it in the light of an element strange, useless, arbitrary. It rejects, for this reason, doctrines purely speculative as well as facts purely marvelous. Man requires his religion to be entirely religious; that is to say, to be in all respects in direct relation with piety, and, so to speak, to be vertical to his conscience. The more his faith purifies itself, the more a man eliminates from his religion dogmas which, having no root either in the divine nature or man's nature, appear on that very account to have no ground to exist at all. "At first sight this gradual emancipation of faith and this corresponding progress of religion in the ways of Spiritualism, seem a natural process by means of which religious opinion and the human mind contrive to maintain themselves in a state of constant equilibrium. {258} We imagine all difficulties removed, and fancy that we catch a glimpse of the religious future of humanity in a sort of Christian Rationalism, a rational Christianity not excluding fervor of devotion, but leaving all its liberty to man's thought.
