Ferdinand Schlingensiepen, a scholar on Nazi-era church resistance leader Dietrich Bonhoeffer, will speak at 7 p.m. Thursday at Trinity Lutheran Church, 1245 N.H.

A founding member of the Dietrich Bonhoeffer Society, Schlingensiepen wrote a biography on the German Confessing Church leader, who stood up to Hitler’s persecution of the Jews. Bonhoeffer was executed by the Nazis in 1945, less than a month before the Nazis’ surrender.

Schlingensiepen’s talk, called “Dietrich Bonhoeffer, 1906-1945. Martyr, Thinker, Man of Resistance,” is part of the annual Theologian in Residence Program, sponsored by a consortium of campus ministries at Kansas University, Lawrence congregations, KU’s religious studies department and the philosophy departments of Baker and Washburn universities. The talk is free and open to the public.

There is a companion event — a question and answer session — from noon to 1:30 p.m. Friday, upstairs at Genovese, 941 Mass. Food and drink will be available for purchase.
