Klaus Berger (born November 25, 1940 in Hildesheim) is a German theologian known for his study and writings concerning the New Testament. He has been quoted in several Catholic news sources leading to the notion he was Catholic or somehow "both Catholic and Protestant." This idea has been rejected by the Roman Catholic Church.[1] But as a fact and after a long controversy he left the Evangelische Landeskirche Baden, a Protestant church, and again became member of the Roman Catholic church (in the diocese of Hildesheim, Germany). All of this should not lead astray from a high esteem of Berger as theologian who was repelling some modernist theses as the one which explains the miracles of Jesus and his title as messias as an idea of the proceeding of post-resurrection Christians.
