Abstract

The article concentrates on theoretical and practical aspects of reformist activity undertaken by clergyman and baron Ignaz Heinrich von Wessenberg (1774-1860) who, originally as a vicar-general (1802-1817) and later as the administrator of the diocese of Constance (1817-1827). He ineffectively advocated the autonomy of German National Church, with its own primate and synod, as well as abolition of clerical celibacy. However, the founder of Wessenbergianism was successful in developing innovative educational system for children, teenagers and clargy and also in introducing German language in liturgical services, sacraments and sacramentals. It is to his credit that he widespread, among clergy and congregation members, the German version of the Bible and Fathers of the Church writings. He also constricted pilgrimage and hagiolatry. In reaction to Wessenberg's reforms Pope Leo XII (1823-1829) dissolved the diocese of Constance which became part of the newly established archdiocese of Freiburg. Most of Wessenberg's ideas and demands were addressed by Old Catholic Churches, which resulted in synodal and episcopal polity restoration as well an introducing national languages in liturgical services, restricting bigotry an abolition of clerical celibacy.
