The Claims of Truth presents an exposition and analysis of the theology of the great Puritan theologian, John Owen, which pays particular attention to his vigorous trinitarianism. The author argues that the only way to understand Owen is to see him as a seventeenth-century representative of the ongoing Western trinitarian and anti-Pelagian tradition. In chapters which deal with Owen's historical context, his understanding of the principles of theology, his understanding of God, his Christology, and his understanding of atonement, Dr. Trueman demonstrates how Owen used the theological insights of patristic, medieval, and Reformation theologians in order to meet the challenges posed to Reformed Orthodoxy by his contemporaries. The picture that emerges is one of a theologian whose thought, in its context, represented a critical reappropriation of aspects of the Western tradition for the purpose of developing a systematic restatement of Reformed theology which was capable of withstanding the assaults of both the subtly heterodox and the openly heretical.
