The revival of Trinitarian studies in the twentieth century ushered in a new era of theological innovation. The renewed and dedicated articulation of the Trinity as a doctrine in its own right is indeed noteworthy, but more important and praiseworthy are the recent endeavours of theologians to integrate the doctrine of the Trinity with other Christian doctrines and with the many variegated aspects of the life and ministries of the church. Today, it is common to encounter the term ‘Trinitarian’ being used as a modifier: Trinitarian worship, Trinitarian ecclesiology, etc. This book presents Thomas F. Torrance as a participant theologian in this integrative paradigm. Because Torrance argues that the Trinity is ‘the ground and grammar of theology’, his doctrine of salvation is consistently Trinitarian. But how did he formulate his unique Trinitarian soteriology? Communion with the Triune God seeks to answer this question.
