the Congress of Vienna in 1815. Vicar general A progressive churchman, he set about to abolish everything he considered superfluous or superstitious about religious customs. He did away with various holy days of obligation in the cantons of Aargau and St. Gallen in 1806, and cooperated with the Napoleonic Swiss government at Lucerne in the suppression of monasteries. He gained the support of the clergy, but in the Swiss portion of the Diocese of Constance, Wessenberg's innovations aroused great dissatisfaction. His orders in case of mixed marriages (1808) to permit the male offspring to be brought up in the religion of the father, the female in the religion of the mother; and especially his many matrimonial and other dispensations that exceeded his competence induced Fabrizio Sceberras Testaferrata, the papal nuncio at Lucerne, to call him to account, but Wessenberg insisted that nothing had been done which exceeded the jurisdiction of the Bishop of Constance, giving Testaferrata at the same time to understand that he did not recognize the Apostolic Nunciature. Wessenberg attended the Congress of Vienna Congress (1814/15) as the authorized representative of Prince Primate Dalberg, to press for a reorganization of the German church under the leadership of a primate and for the conclusion of a concordat with the Holy See covering all German states. His efforts failed due to the particular interests of both the sovereigns and the Roman Curia. The sovereigns sought state bishops, each subject to their respective rulers, while the Curia was not inclined to see a unified German church with a primitive leadership, like the previous of imperial church structure. During his administration he was especially noteworthy his deep solicitude for a better training and stricter discipline of the clergy and his insistence on regular Sunday sermons in parish churches and semi-weekly religious instructions in the state schools. He established regularly scheduled pastoral conferences for the continuing education of the clergy. He published a number of prayer books and hymn books for use in his diocese. While he did not reject the traditional forms of Baroque popular piety, as his focus was on strengthening the parishes, he did particularly encourage pilgrimages, festivals, brotherhoods, or people attending monastery churches instead people. After various requests from the Catholics of Switzerland, Pope Pius VII put an end to Wessenberg's reformist plans in that part of the diocese by severing the Swiss cantons from the Diocese of Constance,
