The spirit of Christ in regard to slavery, for instance, was made manifest fully only in our day. The true relations of men to each other, as conceived by our blessed Lord, are evidently about to be forced home upon the world by the turmoils, the strikes, and the outrages, by the wild demands, and the wilder hopes which are the characteristic of our epoch. In the future, too, there must lie experiences which will make manifest to men the brand which the spirit of Christ puts upon war, with its savagery and its folly. These are only noteworthy instances of the explanation of revelation by the developments of the Divine purpose in the world. But in countless ways the same process is going on, and the Church which refuses to regard it is preparing a decay of its own life. For man lives by _every_ word that proceedeth out of the mouth of God, and every such word missed means a loss of vitality. The Christian Church, therefore, if it is to be true to its calling, should be seriously watchful lest any Divinely sent experience should be lost to it. It cannot be indifferent, much less hostile, to discoveries in physical science; it cannot ignore any fact or lesson which history reveals; it cannot sit apart from social experiments, as if holding no form of creed in such things, without seriously impairing its chances of life. For all these things are pregnant with most precious indications of the mind of God, and to turn from them is to sit in darkness and the shadow of death. In the most subtle and multifarious way, the inner spiritual life of man is being modified by the discoveries of scientists, historians, philologists, archæologists, and critics, and by the new attention which is being given to the foundations of society and social life. All the truth that is in these discoveries issues from the mouth of God. They too are a Bible, as Mommsen says, and if the Christian Church cannot "hinder the fool from misunderstanding and the devil from quoting them," it can itself listen with open ear to these teachings, and work them into coherent unity with the great spiritual Revelation. This is the perennial task which awaits the Church at every stage of its career, for on no other terms can it live a healthy life.
