Since the European Enlightenment of the 18th century, traditional religious faith has been challenged from many sides. Both the modern and postmodern worldviews have confronted religious belief. The Christian doctrine of God is no exception. Premodern Faith in a Postmodern Culture: A Contemporary Theology of the Trinity acknowledges these challenges to the Christian doctrine of God and explains their sources in philosophical terms. Through careful, thoughtful analysis, Peter Drilling offers a way to meet these challenges so that Christian Faith in the triune God survives and thrives. By using the theological method articulated by the philosopher-theologian Bernard Lonergan, this book demonstrates a reasonable and authentic process of coming to faith. This method includes various directions believers can take, both theoretical and practical, to apply faith in the Trinity. Drilling's multi-faceted approach looks at this faith through the diverse perspectives of analogous understanding, spirituality, ecclesiology, philosophy, and interreligious dialogue. This work is unique in its view of the entire historical development of the Trinity, from historical sources to the new, postmodern conceptions of God.
