This study has led us into many curious regions and shown to what unexpected conclusions the forces of faith or hope, once released, may come, but surely it has revealed nothing more curious than that the old, old controversy as to the true successor of Mohammed the prophet should at last have issued in a universal religion and set the faithful to building a temple of unity on the shores of Lake Michigan. If this work were to be complete it should include some investigation of the rituals of the cults. They are gradually creating hymns of their own; their public orders of service include responsive readings with meditations on the immanence of God, the supremacy of the spiritual and related themes. In general they dispense with the sacraments; they have no ecclesiastical orders and hardly anything corresponding to the Catholic priesthood or the Protestant ministry, though the Christian Science reader has a recognized official place. They meet in conferences; they depend largely upon addresses by their leaders. Spiritualistic movements organize themselves around seances. They use such halls as may be rented, hotels, their own homes; they have not generally buildings of their own save the Christian Science temples which are distinctive for dignity of architecture and beauty of appointment in almost every large city. _General Conclusions; the Limitations of the Writer's Method_ It remains only to sum up in a most general way the conclusions to which this study may lead. There has been a process of criticism and appraisal throughout the whole book, but there should be room at the end for some general statements. The writer recognizes the limitations of his method; he has studied faithfully the literature of the cults, but any religion is always a vast deal more than its literature. The history of the cults does not fully tell their story nor does any mere observation of their worship admit the observer to the inner religious life of the worshippers. Life always subdues its materials to its own ends, reproduces them in terms of its own realities; there are endless individual variations, but the outcome is massively uniform. Religion does the same thing. Its materials are faiths and obediences and persuasions of truth and expectations of happier states, but its ultimate creations are character and experience, and the results in life of widely different religions are unexpectedly similar. Both theoretically and practically the truer understanding or the finer faith and, particularly, the higher ethical standards should produce the richer life and this is actually so. But real goodness is everywhere much the same; there are calendared saints for every faith.
