Do the recent revelations discredit his theology?
I knew that Karl Barth, arguably the greatest Protestant theologian of the 20th century, had a decades-long affair with his personal assistant, Charlotte von Kirschbaum. But I didn’t know some of the details. As the saying goes, the devil is in the details, and the details were deeply disappointing.
As the author of the recently released Karl Barth: A Biography for Evangelicals, I was anxious to read the latest revelations about the relationship. I had briefly discussed it in the book, noting the pain it caused his wife, Nelly, especially when Barth not only admitted to his wife his love for Charlotte but also insisted that Charlotte move into the family home to help him with his workload. Based on the work of Barth scholar George Hunsinger, I tried to set the relationship in the context: A younger Barth had fallen in love with a woman his father forbade him from marrying; his marriage to Nelly was in some sense arranged. So Barth was an emotionally lonely man. But I concluded that even if it was merely emotional adultery:
Husbands of much lesser stature have recognized that when such a relationship sabotages the very integrity of one’s marriage and becomes a burden to the family, it may suggest a duty to sacrifice one’s desires for the sake of one’s vows.
Then I read “Karl Barth and Charlotte von Kirschbaum” by Christiane Tietz in Theology Today, which discusses recently released personal letters Barth wrote to von Kirschbaum from 1925–1935. I was stunned. It wasn’t merely that Barth had committed adultery or that a great theologian was shown to be not so great in his personal life. As church history shows time and again, sin is no respecter of persons, no matter how great.
