The foundation aims to enable the Roman Catholic Church to exercise pastoral care in the area of the canonically defined parish of Ingenbohl-Brunnen and to enable the Roman Catholic residents of this parish to fulfill their ecclesiastical-religious duties by making the Theresia Church and other ecclesiastical properties available, as well as to facilitate this through the corresponding yields. It guarantees the Roman Catholic cult and contributes to the maintenance of the ecclesiastical assets made available, as far as possible within the framework of ordinary administration. In addition, the purpose and ordinary and extraordinary administration of the Theresia Church Foundation are determined by canonical law.
