Here we find the answer to timid Christians who address petulant complaints to those who are called to attempt this work. If, say they, these new thoughts are not essential to faith, if in the forms to which we have been accustomed the essence of true religion has been preserved, why do you disturb the minds of believers by outside questions? The reply is that we dare not refuse the teaching which God is sending us in these ways. To refuse light is to blaspheme light. Though we might save our generation some trouble by turning our back upon this light, though we might even save some from manifest shipwreck of faith, we should pay for that by sacrificing all the future, and by rendering faith impossible perhaps for greater multitudes of our successors. Yet this does not imply that the Church is to be driven about by every wind of doctrine. Some men of science demand, apparently, that every new discovery, in its first crude form, should be at once adopted by the Church, and that all the inferences unfavourable to received views of religion, which occur to men accustomed to think only truths that can be demonstrated by experiment, should be registered in its teachings. But such a demand is mere folly. The Church has in its possession a body of truth which, if not verifiable by experiment, has been verified by experience as no other body of truth has been. Even its enemies being judges, no other system of a moral or spiritual kind has risen above the horizon which can for a moment be compared with Christianity as the guide of men for life and death.[66] Through all changes of secular thought, and amid all the lessons which the world has taught the Church, the fundamental doctrines have remained in essence the same, and by them the whole life of man, social, political, and scientific, has ultimately been guided. Immense practical interests have therefore been committed to the Church's keeping, the interests primarily of the poor and the obscure. She ought never to be tempted, consequently, to think that she is moving and acting in a vacuum, or manage her affairs after the manner of a debating society. It is no doubt a fault to move too slowly; but in circumstances like that of the Church, it can never be so destructive to the best interests of mankind as to move with wanton instability. Her true attitude must be to prohibit no lines of inquiry, to open her mind seriously to all the demonstrated truths of science with gladness, to be tolerant of all loyal effort to reform Christian thought in accordance with the new light, when that has become at all possible. For her true food is everything that issues from the mouth of God; and only when she receives with gratitude her daily bread in this way also, can her life be as vigorous and as elevated as it ought to be.
