" Hence a necessary consequence of the physical and, at the same time, the moral predisposition in us, the latter being the basis and the interpreter of all religion, is that in the end religion will gradually be freed from all empirical determining grounds and from all statutes which rest on history and which through the agency of ecclesiastical faith provisionally unite men for the requirements of the good; and thus at last the pure religion of reason will rule over all, “so that God may be all in all. "
― Immanuel Kant , Religion within the Limits of Reason Alone
