There is an abundant testimony in the literature of the cults to rare goodnesses and abundant devotion, and observation confirms these testimonies. Something of this is doubtless due to their environment. The Western cults themselves and the Eastern cults in the West are contained in and influenced by the whole outcome of historic Christianity and they naturally share its spirit. If the churches need to remember this as they appraise the cults, the cults need also to remember it as they appraise the churches. Multitudes of Catholics and Protestants secure from a religion which the cults think themselves either to have corrected or outgrown exactly what the cults secure--and more. Such as these trust God, keep well, go happily about their businesses and prove their faith in gracious lives. There is room for mutual respect and a working measure of give and take on both sides. The writer is inclined to think the churches at present are more teachable than the more recent religious movements. For a long generation now the churches have been subject to searching criticism from almost every quarter. The scientist, the sociologist, the philosopher, the publicist, the discontented with things as they are and the protagonist of things as they ought to be, have all taken their turn and the Church generally, with some natural protest against being made the scapegoat for the sins of a society arrestingly reluctant to make the Church's gospel the law of its life, has taken account of its own shortcomings and sought to correct them. The cults are as yet less inclined to test themselves by that against which they have reacted. But this is beside the point. The movements we have been studying can only be fairly appraised as one follows through their outcome in life and that either in detail or entirety is impossible. But it is possible to gain from their literature a reasonable understanding of their principles and interrelations and this the writer has sought to do. _The Cults Are Aspects of the Creative Religious Consciousness of the Age_
