If the Church were led to wipe out of existence all products of the thinking of nineteen Christian centuries and start fresh, the loss, even if the Bible were retained, would be immense. When it is once admitted that a body of facts lies at the basis of the Christian religion, the efforts which past generations have made toward the classification of the facts will have to be treated with respect. In no branch of science would there be any real advance if every generation started fresh with no dependence upon what past generations have achieved. Yet in theology, vituperation of the past seems to be thought essential to progress. And upon what base slanders the vituperation is based!

After listening to modern tirades against the great creeds of the Church, one receives rather a shock when one turns to the Westminster Confession, for example, or to that tenderest and most theological of books, the “Pilgrim’s Progress” of John Bunyan, and discovers that in doing so one has turned from shallow modern phrases to a “dead orthodoxy” that is pulsating with life in every word. In such orthodoxy there is life enough to set the whole world aglow with Christian love.
