2012 will mark 60 years since the death of Walter Williamson Bryden. This reprint of his bold 1940 publication, featuring a new introduction by Dr John A. Vissers, Principal of Knox College, Toronto, celebrate the work of this eminent Presbyterian theologian. Best known for bringing Karl Barth to Canada, W.W. Bryden predicted the decline of Idealism and liberal theology in Protestantism at the start of the twentieth-century. When that crisis hit the Canadian Protestant Churches he was ready with this book. The Christian's Knowledge of God is a re-examination of Reformation teachings with particular focus on the revelation of God, by God through Christ. Bryden challenges his readers to question their blind acceptance of Christian doctrine and to reconsider what it means to have knowledge of the Divine and with it "the power to confront the world, no longer as those seeking, but as those having found God". Although the book concludes "Tempora mutantur, nos et mutamur in illis", we have not changed so much with the times as to make this book less relevant today than it was when first published. Indeed those seeking for knowledge of God today could do well to be reminded of Bryden's message.
