Ignaz Heinrich von Wessenberg

Ignaz Heinrich Karl von Wessenberg (4 November 1774 – 9 August 1860) was a German writer and scholar, and liberal Catholic churchman as well as Vicar general and administrator of the Diocese of Constance. Imbued from his early youth with Josephinistic and Febronian principles, he advocated a German National Church, somewhat loosely connected with Rome, supported by the State and protected by it against papal interference. He encouraged the use of the vernacular in liturgical texts, the hymn book and the regular Sunday sermon.
