The following article aims at showcasing the changes in the attitude of the Catholic Church towards various sects against the backdrop of the transformations in the Polish Upper Silesia. According to the Catholic Church, the existence of various sects contributed to the further destabilization of the world, already shaken by the events of World War I, and broke social order as well religious unity. For these reasons, apart from the obvious differences in dogma, the Church in the Polish Upper Silesia strongly opposed sectarian movements. The most effective way to counteract these perceived issues was, according to the Church, to discredit the sectarians in the eyes of the Catholic public. For that reason, the Catholic press published reports showing the devastating impact of sects on family life, vocational success or even personal happiness. However, in seeking help from the state, the Church had put itself in a precarious position, since the Church’s stance against the tolerant religious attitudes of the Second Polish Republic could have been perceived as nostalgia for the Prussian times and thus anti-patriotic. The principled position of the Catholic Church, as well as a desire to exclude other sects and the members of religious minorities from the Catholic ecclesiastical authority, created a precedent that promoted religious - and, in consequence, also social - intolerance. The right to a monopoly on spreading their ideology was a source of tension; however, that did not stop the process of social integration.
