Gregory Walter is a systematic theologian.  His work concerns trinitarian ontology, the relationship of theology to disciplines such as philosophy of religion, natural science, and social theory, as well as the scope, truth, and upshot of theological claims.

Walter’s work has contributed to scholarly discussions of theological rationality, hermeneutics, the secular, liturgy, and interreligious theology.   He has also contributed to scholarship about several figures: Martin Luther, Johann Georg Hamann, Friedrich Schleiermacher, Karl Holl, Hans-Joachim Iwand, and Paul Tillich. Walter published his first monograph, Being Promised: Theology, Gift, and Practice in 2013, which considered promise as a form of gift-exchange and developed a theology of place. 

He is currently working on two projects. The first is a long-term project reconstructing theology as a form of inquiry in conversation with pragmatism. The second is a monograph-length theological account of the crucifixion of Jesus, otherwise known as the theology of the cross.

He speaks frequently at congregations of the Evangelical Lutheran Church in America (ELCA) on religious pluralism, Lutheran theology, liturgy, and other concerns.  He has also served on a task force for the ELCA’s church-wide office on ecclesiology.

Walter tries to keep up with his busy family. He might be the only member of the St. Olaf College faculty who closely follows Prince Valiant’s weekly adventures in the Sunday comics page.
