While Jonathan Edwards scholars have increasingly recognized the central role that the Trinity played in his thought, no work brings together Edwards' central texts on the Trinity and interprets and applies them to contemporary theological issues. This book reveals how the doctrine of the Trinity transformed Edwards' ministry and how the Trinity can inform current evangelical thought, life, and ministry. Key primary texts, interpretation, and application of Edwards' trinitarian theology are all presented here. Part one features Edwards' chief trinitarian writings and provides an in-depth analysis on his doctrine. Part two sets Edwards' trinitarianism in historical context. Part three demonstrates how Edwards employed the Trinity in his sermons, in spiritual formation, and in other areas of doctrine.
