Duke Chapel Dean Luke A. Powery preached a sermon titled And on June 29, 2025, at the Castle Church in Wittenberg, Germany, made famous by the posting of Martin Luther’s Ninety-five Theses.
Dean Powery was in Wittenberg and Leipzig, Germany, for a theological conference “Homiletic Fire: Preaching and the Holy Spirit” organized by the Center for Protestant Worship and Preaching Culture. At the conference, he addressed the theology faculty of the University of Leipzig on the topic of “Traces of the Homiletic Spirit” and led a workshop on “Preaching in a Spiritual Key.”
“Ascending to the pulpit is not giving a lecture or a speech,” he said in his lecture. “As many Christians profess, the social practice of preaching makes sense only within an understanding of the work of the Holy Spirit.”
