Klaus Berger (25 November 1940 – 8 June 2020) was a German academic theologian.

Berger was Professor of New Testament Theology at the University of Heidelberg.

This idea was rejected by the Roman Catholic Church[1] and, after this controversy, he left the Protestant Church in Baden and became a member once more of the Roman Catholic Church (in the diocese of Hildesheim, Germany).

Later he married translation scholar Christiane Nord.

He was a familiaris of the Cistercian Abbey of Heiligenkreuz in the Vienna Woods.
