How did Anton Webern's religious beliefs differ from Roman Catholic church doctrine?

Anton Webern’s personal religious views diverged from Roman Catholic church doctrine primarily through his rejection of institutional hierarchy and dogma. While he was considered deeply religious, his faith was characterized by a pantheistic perspective rather than adherence to traditional ecclesiastical structures.1

Specifically, Webern rejected the role of the priest as an essential intermediary between God and humanity. This independence from church authority was also reflected in his personal life; for instance, he and his wife, Wilhelmine Mörtl, were first cousins, a union prohibited by the Roman Catholic Church at the time. Consequently, their marriage was not solemnized until 1915, several years after the birth of three of their four children.1
