ULTRAMONTANISM – PAPAL SUPREMACY – PRIMACY – INFALLIBILITY – INDEFECTIBILTY: – Pastor aeternus (“First Dogmatic Constitution on the Church of Christ”) was issued by the First Vatican Council (POPE PIUS IX), July 18, 1870. The document defines four doctrines of the Catholic faith: the apostolic primacy conferred on Peter, the perpetuity of the Petrine Primacy in the Roman pontiffs, the definition of the papal primacy as a papal supremacy, and Papal infallibility – infallible teaching authority (magisterium) of the Pope.

[W]e teach and declare that, by divine ordinance, the Roman Church possesses a pre-eminence of ordinary power over every other Church, and that this jurisdictional power of the Roman Pontiff is both episcopal and immediate. Both clergy and faithful, of whatever rite and dignity, both singly and collectively, are bound to submit to this power by the duty of hierarchical subordination and true obedience, and this not only in matters concerning faith and morals, but also in those which regard the discipline and government of the Church throughout the world. – Dogmatic constitution Pastor aeternus.

PAPAL SUPREMACY is the doctrine of the Catholic Church that the Pope, by reason of his office as Vicar of Christ, the visible source and foundation of the unity both of the bishops and of the whole company of the faithful, and as priest of the entire Catholic Church, has full, supreme, and universal power over the whole church, a power which he can always exercise unhindered: that, in brief, “the Pope enjoys, by divine institution, supreme, full, immediate, and universal power in the care of souls.”

PAPAL PRIMACY, also known as the primacy of the bishop of Rome, is an ecclesiological doctrine in the Catholic Church concerning the respect and authority that is due to the pope from other bishops and their episcopal sees. The Catholic Church attributes to the primacy of the pope “full, supreme, and universal power over the whole Church, a power which he can always exercise unhindered,” a power that it attributes also to the entire body of the bishops united with the pope.

PAPAL INFALLIBILITY is a dogma of the Catholic Church which states that, in virtue of the promise of Jesus to Peter, the Pope when he speaks ex cathedra is preserved from the possibility of error on doctrine “initially given to the apostolic Church and handed down in Scripture and tradition”. It does not mean that the pope cannot sin or otherwise err in some capacity, though he is prevented by the assistance of the Holy Spirit from issuing heretical teaching even in his non-infallible Magisterium, as a corollary of indefectibility. 

This doctrine, defined dogmatically at the First Vatican Council of 1869–1870 in the document Pastor aeternus, is claimed to have existed in medieval theology and to have been the majority opinion at the time of the Counter-Reformation.

The doctrine of infallibility relies on one of the cornerstones of Catholic dogma, that of papal supremacy, whereby the authority of the pope is the ruling agent as to what are accepted as formal beliefs in the Catholic Church. The use of this power is referred to as speaking ex cathedra. “Any doctrine ‘of faith or morals’ issued by the pope in his capacity as successor to St. Peter, speaking as pastor and teacher of the Church Universal [Ecclesia Catholica], from the seat of his episcopal authority in Rome, and meant to be believed ‘by the universal church,’ has the special status of an ex cathedra statement. 

Vatican Council I in 1870 declared that any such ex cathedra doctrines have the character of infallibility. – Wiki –

PAPAL INDEFECTIBILITY extends to the person of the Roman Pontiff, that his faith will not fail, and to the exercise of the Keys of Peter by the Roman Pontiff, that his non-infallible teachings and decisions of discipline will not err gravely and will not lead the faithful away from the true Church and the true path of faith, morals, and salvation taught by Jesus Christ. Errors are still possible, but these errors can never rise to the extent of harming the indefectibility of the Church, nor of defection from the true faith by the Roman Pontiff, the See of Peter, the body of Bishops, or the body of the faithful.

* The Pope can never fall into apostasy, heresy, or schism.

* The Pope can never lose his office, by a failure of faith, and so become a false Pope or antipope.

* A heretic elected to the office of Roman Pontiff (e.g. Vigilius 537-555) will be converted by the prevenient grace of God, and so become a rock of faith instead of a heretic.

* Every non-infallible teaching of the Roman Pontiff under the Keys of Peter is free from every grave error, but not necessarily free from all error.

* The Pope can err in his personal opinions, to a greater extent, but never to the extent of apostasy, heresy, or schism as the person of the Roman Pontiff, as well as his exercise of the office, has a never-failing faith.

* Since the indefectible Roman Pontiff confirms his brother Bishops in the faith, the body of Bishops (as a body, not individually) is also preserved from grave error in doctrine and discipline and from defecting away from the faith, as a body, by apostasy, heresy, or schism.

* The indefectible Roman Pontiff also confirms the faithful in the faith, as is clear from the threefold commission of Jesus to Peter to feed his sheep and lambs. Therefore, the faithful, as a body, cannot defect from the faith by apostasy, heresy, or schism. – The Reproach of Christ –

ULTRAMONTANISM is a clerical political conception within the Catholic Church that places strong emphasis on the prerogatives and powers of the Pope. It contrasts with Gallicanism, the belief that popular civil authority—often represented by the monarch’s or state’s authority—over the Church is comparable to that of the Pope.

Catholic integralism is an interpretation of Catholic social teaching that argues for an authoritarian and anti-pluralist Catholic state, wherever the preponderance of Catholics within that society makes this possible; it was born in 19th-century Portugal, Spain, France, and Italy.

Catholic integralism does not support the creation of an autonomous “Catholic” State Church, or Erastianism (Gallicanism in French context). Rather, it supports subordinating the state to the moral principles of Catholicism. Thus, it rejects separating morality from the state and favours Catholicism as the proclaimed religion of the state. 

The idea that temporal political authority should be subordinated to man’s ultimate, spiritual end is a common theme – if not the main theme – of contemporary Catholic integralism. 

Proponents of Catholic political integralism taught that all social and political action ought to be based on the Catholic Faith. They rejected the separation of church and state, arguing that Catholicism should be the proclaimed religion of the state. – Wiki –
