In this special episode, guest host Tim Grundmeier interviews historian and author Benjamin T. Phelps about his recent Wisconsin Lutheran Quarterly article on Dr. Henry A. Koch—a pastor, professor, and editor who left a profound mark on confessional Lutheranism in both Germany and America. Phelps shares personal insights drawn from years of research, including access to Koch’s letters, diary, and unpublished materials preserved by his family. Together, they trace Koch’s theological formation in Wauwatosa, his academic work in Leipzig, his resistance to Nazi ideology, and his return to America without a call during the Great Depression. The conversation explores Koch’s role in rebuilding fractured congregations, his deep concern for doctrinal faithfulness, and his controversial but principled opposition to the Missouri Synod’s growing unionism. Through it all, Koch remained committed to the Lutheran confession and the gospel ministry—living out the motto he printed for decades in the Gemeinde-Blatt: Halte, was du hast—Hold fast what you have.
