Since the Reformation, Protestant Christians have believed in the principle of sola Scriptura. But when Christian doctrine is examined closely, there are clear indications of its true intellectual roots. Through a long historical process, philosophy and human tradition have gradually replaced and distorted Christian teachings. In this book, Canale examines the causes behind this distortion. He explores the reality of God, his Trinitarian nature, his presence, his predestination, and his creation; first presenting and then contrasting arguments from Christian tradition and the Bible.
