This picture of our age is not an unjust one. The modern mind is thoroughly wide awake and has quite thrown off the leading-strings of ancient timidity. It looks all questions in the face and demands to be shown the real facts in every realm. All the traditions of history, the laws of science, the principles of morals are overhauled, and the foundations on which they rest relentlessly probed. And our modern curiosity can see no reason why it should cease its investigations when it comes to the frontiers of religion. It deems no dogma too old to be summoned before its bar; no council nor conclave too sacred to be asked for its credentials; no pope or Scripture too venerable to be put in the witness-box and cross-examined as to its accuracy or authority. In all the churches there is a spirit of inquiry abroad; almost every morning breeze brings us some new report of heresy, or the baying of the sleuth-hounds of orthodoxy, as they scent some new trail of infidelity; and the slogan of dogmatic controversy echoes from shore to shore. As we look around the ecclesiastical horizon, we find agitation and controversy on all sides. In one denomination, it is the question of the salvation of the _heathen_; in another, that of the virgin birth of Christ and the apostolic succession; in a third, it is the invasion of doubt as to the eternal torment of the wicked; in a fourth, the evidential value of the miracles; in a fifth, the grand questions included under the higher criticism of the Scriptures and the relative authority of reason and the Bible. In Congregational, Episcopalian, Baptist, Universalist, and Presbyterian folds, it is the same, everywhere some heresy to be disciplined, some doubt to be suppressed, some doctrinal battle hotly waged. To the greater part of the Church, this epidemic of scepticism is a subject of grave alarm. Unbelief seems to them, as to Mr. Moody, the worst of sins; and they consider the only proper thing to do with it, is to follow the advice of the Bishop of London, some years ago, and fling doubt away as you would a loaded shell. They apparently look upon Christianity as a huge powder magazine, which is likely to explode if a spark of candid inquiry comes near it. Others, on the contrary, fold their arms indifferently and regard this new spirit of investigation as only an evanescent breeze, which can produce no serious result upon the citadel of faith. A third party hail it with exultation as the first trumpet blast of the theological Goetterdaemerung, the downfall of all divine powers and the destruction of the Christian superstition, to give place to the naked facts of scientific materialism. What estimate, then, shall we put on this tendency?
