The young, who are the hope of the future, can be won and held only by the highest ideals, in the light of which they may thrill with hope and feel that it is a blest thing to be alive and active, to fight the good fight and, if need be, to perish in a worthy cause. To speak to them with contempt of what the nineteenth century has done, of its science and literature, of its truer knowledge of the past, its keener critical sense, its amazing progress in carrying out the divine command that all things be made subject to man, of the success with which it has battled against ignorance, poverty, and disease, would be to fill them with contempt for ourselves, as being men without understanding and without heart. We must indeed warn against pride and conceit and halfness and dilettanteism, against irreverence and knowingness; but it were a fatal mistake to imagine that we can do aught but harm by seeking to inspire them with a distrust of science and culture, or with a dread of the influence of such things on religious faith. We of all men should be able to walk with confidence in the paths of knowledge. Since we are glad to receive money and to have the favor of men in high places to assist us in our spiritual work, how shall we be willing to lack the help of thoroughly disciplined and enlightened minds, to lack the power of thought which is the most irresistible force God has given to man? If we look upon theology as merely a system of crystallized formulas, as a science which need take no cognizance of the general culture of the age, content with presenting the old truths in the old way, as merely a larger catechism, with a more detailed exposition of definitions and refutations, we deprive it of power to influence men who are all alive with thoughts urgent as the growth of wings; who in the midst of problems which the new sciences raise and accentuate, have grown confused and begin to doubt whether human life shall not be emptied of its spiritual content. All knowledges are related, as all bodies attract and help to hold one another in place; and if we hope to commend and enforce revealed truth with efficacious power, we must be prepared to do so in the full blaze of the light which research and discovery have poured upon nature and the history of man. If, in consequence, we find it necessary to abandon positions which are no longer defensible, to assume new attitudes in the face of new conditions, we must remember that tho the Church is a divine institution, it is none the less subject to the law which makes human things mutable, that tho truth must remain the same, it is capable of receiving fresh illustration, and that if it is to be life-giving, it must be wrought anew into the constitution of each individual and of each age.
