In Premodern Faith in a Postmodern Culture, Peter Drilling presents a how-to guide to assist believers in seeing how the process of coming to faith in the triune God of the Christian tradition is not only reasonable and authentic in its original development, but also continues to be relevant in light of modern and postmodern challenges. This work implements Bernard Lonergan's method to highlight the consistency of the Christian faith and includes various directions believers can take, both theoretical and practical, to apply faith in the Trinity.
