As to the future of Mrs. Eddy's church, her own attitude toward every attempt to investigate and to apply liberally the principle of mental healing, seems to determine that. It has been possible for her, during her own lifetime, absolutely to prohibit preaching, thinking, independent writing,--investigation or inquiry of any sort--in her churches. But after her death, when that compelling hand is withdrawn, either the church must renew itself from among the ignorant and superstitious, as Mormonism has done, or it must permit its members to use their minds. Those who use their minds will discover that Christian Science is only one method of applying a general truth, and that it is a method which is hampered by a great deal that is illogical and absurd; that if Christian Science, as Mrs. Eddy has promulgated it, were universally believed and practised, it would be the revolt of a species against its own physical structure; against its relation to its natural physical environment, against the needs of its own physical organism, against the perpetuation of its kind. The moment a Christian Scientist realizes that the helpful and hopeful principle of his religion can operate quite independently of all the inconsequential theories which Mrs. Eddy has attached to it, that moment he is, of course, lost to Mrs. Eddy. Mrs. Eddy's church organization stands as a sort of dyke between the general principle of mind cure and Mrs. Eddy's very empirical, violent, and temperamental interpretation of that principle. It is the future of psycho-therapeutics that will determine the future of Christian Science. If "Mind Cure," "Christian Psychology," and regular physicians offer the benefits of suggestive treatment in a more rational and direct way than does Christian Science, Mrs. Eddy's church will find in them very formidable competition. On the other hand, if Christian Scientists throw down their barriers and join the general mind-cure movement, and the two branches of Quimbyism meet, then half of Mrs. Eddy's life-work is lost. The labor of her days has been to keep these two streams apart; to prove one the true and the other the false. Her efforts to stem the progress of all other schools of mental healing have been secondary only to her efforts to advance her own. Yet, unconsciously and against her own wish, she has been the most effective instrument in promoting the interest of the whole movement.
