Johann Friedrich (5 May 1836, Poxdorf, Germany – 19 August 1917, Munich, Germany) was a German theologian. He was prominent as a leader of the Old Catholics.
Biography
He was born at Poxdorf in Upper Franconia, and was educated at Bamberg and at the Ludwig-Maximilians-Universität München. He was ordained a Catholic priest in 1859. In 1865, he was appointed extraordinary professor of theology. In 1867, he was appointed to the Academy of Sciences. He was a pupil of Ignaz von Döllinger.
In 1869, he went to the Vatican Council as secretary to Cardinal Hohenlohe, and took an active part in opposing the dogma of papal infallibility, notably by supplying the opposition bishops with historical and theological material. He left Rome before the council closed.
:"No German ecclesiastic of his age appears to have won for himself so unusual a repute as a theologian and to have held so important a position, as the trusted counsellor of the leading German cardinal at the Vatican Council. The path was fairly open before him to the highest advancement in the Church of Rome, yet he deliberately sacrificed all such hopes and placed himself in the van of a hard and doubtful struggle" (The Guardian, 1872, p. 1004).
A sentence of excommunication was passed on Friedrich in April 1871, but he refused to acknowledge it and was upheld by the Bavarian government. He continued to perform ecclesiastical functions and maintained his academic position, becoming an ordinary professor in 1872. In 1874, he inaugurated the Old Catholic theological faculty at the University of Bern and lectured there for a year.
