Rev. Lewis Polzin

Rev. Lewis Polzin (M.Div., M.S.) is a Lutheran pastor, theologian, and educator, gladly serving as the pastor of St. Mark Lutheran Church in Belgium, Wisconsin, a role he began in May 2025 after concluding nearly eight years of ministry at St. Peter–Immanuel Lutheran Church & School in Milwaukee. Ordained in 2013 at Trinity Lutheran Church in Bemidji, Minnesota, where he served for three years, he brings over a decade of pastoral experience rooted in confessional Lutheran theology.

A native of the Milwaukee area, Polzin married his wife, Liz, in 2011, and they have two children. Polzin holds an undergraduate degree from Concordia University Ann Arbor, a Master of Science in Family & Child Studies from Miami University in Ohio, and a Master of Divinity from Concordia Seminary, St. Louis. He is currently completing his PhD at the South African Theological Seminary, focusing on a comparative study of the doctrines of the resurrection as seen in the theologians Johann Gerhard and Joseph Ratzinger (Pope Benedict XVI) and its implications for a sacramental theology.

In addition to his parish work, Polzin serves as a Fellow of Practical Theology at the Weidner Institute at Just & Sinner, where he teaches courses in practical and systematic theology, particularly emphasizing the application of C.F.W. Walther’s “The Proper Distinction Between Law and Gospel.” He hosted the popular podcast “Boars in the Vineyard” from 2013 to 2018. He also serves as the Vice President of Just & Sinner. He teaches as an adjunct professor at Concordia University Wisconsin, contributing to the formation of future church workers and lay leaders through theological instruction. He is also the Visiting Professor for Practical Theology at the America Lutheran Theological Seminary.
