Thomas Torrance was undoubtedly one of the most significant theologians writing in English during the latter half of the twentieth century. This study of his work by Paul Molnar is a sympathetic and a thorough introduction to it. Molnar begins by tracing the life and career of Torrance, highlighting those theologians who exercised a formative influence over him. His next chapter argues for the centrality of the Trinity to all Torrance's thought. Here Molnar emphasises the architectonic significance of the Son's homoousion with the Father in Torrance's endeavour to elaborate a truly scientific theology; by which he meant a theology conditioned by God's own nature as revealed in Christ, rather than by the assumptions of the theologian. Molnar then proceeds through the major dogmatic loci around which Torrance articulated his work: the doctrines of creation, incarnation, reconciliation, pneumatology, eschatology and ecclesiology. In each case, Molnar exhibits the defiantly Trinitarian cast of Torrance's thought, and his desire to expose and avoid any form of Monism and Dualism which might corrode the Nicene faith. Molnar underlines the significance to Torrance of Athanasius' insistence that it is more proper to name God as the Father of the Son, than as the Creator of the world. He also shows how the Ascension assumes a cardinal role in Torrance's approach to eschatology, ecclesiology and the doctrine of the sacraments. Along the way Molnar dwells helpfully on Torrance's use of patristic writings, his commitment to the Reformed tradition and his ecumenical engagement with Roman Catholic and Eastern Orthodox thought. Molnar's final chapter, in which he explores a number of the criticisms which have been made of Torrance's theology, seems a little cursory after the care with which he has expounded the theology itself. The brief rebuttal of Richard Muller's challenge to Torrance (p. 315), for example, does not really take his criticism seriously. There are also occasional generalisations about medieval theology and post-Reformation Protestant theology which might provoke a historian of doctrine. The unqualified assertion, for example, that medieval theologians separated the one God from the Triune God (p. 176) might not bear very close examination. None the less, Molnar succeeds in presenting Torrance's theology with exemplary clarity and insight, and has therefore written a book which invites and deserves a readership wider than that of professional theologians.
