In a previous article we have referred to cyclic changes that came during the last quarter of preceding centuries. Of our remarkable nineteenth century not the least eventful circumstance is the advent of Christian Science. That it should be the work of a woman is the natural outcome of a period notable for her emancipation from many of the thraldoms, prejudices, and oppressions of the past. We do not, therefore, regard it as a mere coincidence that the first edition of Mrs. Eddy's "SCIENCE AND HEALTH" should have been published in 1875. Since then she has revised it many times, and the ninety-first edition is announced. Her discovery was first called "the science of divine metaphysical healing." Afterward she selected the name Christian Science. It is based upon what is held to be scientific certainty, namely,--that all causation is of Mind, every effect has its origin in desire and thought. The theology--if we may use the word--of Christian Science is contained in the volume entitled "SCIENCE AND HEALTH WITH KEY TO THE SCRIPTURES." The present Boston congregation was organized April 19, 1879, and has now over 4,000 members. It is regarded as the parent organization, all others being branches, though each is entirely independent in the management of its own affairs. Truth is the sole recognized authority. Of actual members of different congregations there are between 100,000 and 200,000. One or more organized societies have sprung up in New York, Chicago, Buffalo, Cleveland, Cincinnati, Philadelphia, Detroit, Toledo, Milwaukee, Madison, Scranton, Peoria, Atlanta, Toronto, and nearly every other centre of population, besides a large and growing number of receivers of the faith among the members of all the churches and non-church-going people. In some churches a majority of the members are Christian Scientists, and, as a rule, are the most intelligent. Space does not admit of an elaborate presentation on the occasion of the erection of the temple, in Boston, the dedication taking place on the 6th of January, of one of the most remarkable, helpful, and powerful movements of the last quarter of the century. Christian Science has brought hope and comfort to many weary souls. It makes people better and happier. Welding Christianity and Science, hitherto divorced because dogma and truth could not unite, was a happy inspiration. "And still we love the evil cause, And of the just effect complain; We tread upon life's broken laws, And mourn our self-inflicted pain." (_The Outlook_, New York, January 19, 1895.)
