Best known for bringing Karl Barth to Canada, Walter Williamson Bryden predicted the fall 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 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 ends "Tempora mutantur, nos et mutamur in illis" we have not changed so very 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.
