Catholic integralism suffered a decline after the Second Vatican Council, due to a lack of support from the Catholic hierarchy; during that time, other ideas had been proposed about the relation between the Church and State. However, even the Second Vatican Council finally sided with the integralist understanding in some ways, stating in "Dignitatis humanae" that the council "leaves intact the traditional teaching of the duty which the State owes to the Church", namely, recognition of the Church as the State religion, unless it would be a detriment to the common good. However, the document also affirmed personal freedom of conscience and freedom from coercion, and in the heyday after the council this became the focus of theological discourse, to the exclusion of the traditional teaching on Church–State relations. In the post-conciliar period, Catholic integralism came to be supported mainly by traditionalist Catholics such as those associated with the Society of St. Pius X and various lay Catholic organizations, though some clergy still supported it in theory, if not vociferously.
