Kathryn Tanner is undoubtedly one of the most important contemporary North American theologians. From landmark studies in systematic and constructive theology to economics, Tanner's work is a contribution of inestimable value, hallmarked by its depth, precision, provocativeness, and grace. Unifying the immense scope of her work is the particular vision of God's self-gift: an internal, dynamic, communal reality that is expressed outward in acts of love and generosity that are creation, incarnation, and capacious life in the Spirit. This vision, as the grounding matrix of Tanner's theology, has been extended beyond the disciplinary boundaries of theology in constructive explorations of economics, social and political theory, cultural studies, and ethics. This volume celebrates the vision and breadth of Tanner's unique contribution. Essays by established scholars, colleagues, and former students trace out the key loci and themes, from theological method, the Trinity, Christology, creation, to economics, environmental and social ethics, and politics, to generate constructive and ecumenical conversation that presents Tanner as an important, contemporary public theologian.
