The necessities for moral compromise I have traced in the army, in the law, and in the fields of politics may be found in another form not less conspicuously in the Church. The members, and still more the ministers, of an ancient Church bound to formularies and creeds that were drawn up in long bygone centuries, are continually met by the difficulties of reconciling these forms with the changed conditions of human knowledge, and there are periods when the pressure of these difficulties is felt with more than common force. Such, for example, were the periods of the Renaissance and the Reformation, when changes in the intellectual condition of Europe produced a widespread conviction of the vast amount of imposture and delusion which had received the sanction of a Church that claimed to be infallible, the result being in some countries a silent evanescence of all religious belief among the educated class, even including a large number of the leaders of the Church, and in other countries a great outburst of religious zeal aiming at the restoration of Christianity to its primitive form and a repudiation of the accretions of superstition that had gathered around it. The Copernican theory proving that our world is not, as was long believed, the centre of the universe, but a single planet moving with many others around a central sun, and the discovery, by the instrumentality of the telescope, of the infinitesimally small place which our globe occupies in the universe, altered men's measure of probability and affected widely, though indirectly, their theological beliefs. A similar change was gradually produced by the Newtonian discovery that the whole system of the universe was pervaded by one great law, and by the steady growth of scientific knowledge, proving that vast numbers of phenomena which were once attributed to isolated and capricious acts of spiritual intervention were regulated by invariable, inexorable, all-pervasive law. Many of the formularies by which we still express our religious beliefs date from periods when comets and eclipses were believed to have been sent to portend calamity; when every great meteorological change was attributed to some isolated spiritual agency; when witchcraft and diabolical possession, supernatural diseases, and supernatural cures were deemed indubitable facts: and when accounts of contemporary miracles, Divine or Satanic, carried with them no sense of strangeness or improbability. It is scarcely surprising that these formularies sometimes seem incongruous with an age when the scientific spirit has introduced very different conceptions of the government of the universe, and when the miraculous, if it is not absolutely discredited, is, at least in the eyes of most educated men, relegated to a distant past.
