Klaus Berger (25 November 1940 â 8 June 2020) was a German academic theologian. Berger was Professor of New Testament Theology at the University of Heidelberg.
He is known for his study and publications on the New Testament. He had been quoted in several Catholic news sources to the effect that he was Catholic or somehow "both Catholic and Protestant." This idea was rejected by the Catholic Church and, after this controversy, he left the Protestant Church in Baden and became a member once more of the Catholic Church (in the diocese of Hildesheim, Germany).
Berger had two children from his first marriage with Christa Berger. Later he married translation scholar Christiane Nord. He was a familiaris of the Cistercian Abbey of Heiligenkreuz in the Vienna Woods.
