Old Catholics

Old Catholics, a section of the Roman Catholic Church in Germany and Switzerland that first announced itself in Münich on the declaration in 1870 of the dogma of the infallibility of the Pope, the prime movers in the formation of the protestation against which were Dr. Döllinger and Professor Friedrich, backed by 44 professors of the university; the movement thus begun has not extended itself to any considerable extent.
