Protestantism - Catholicism

Catholicism

The official view of the Catholic Church on the matter is that Protestant denominations cannot be considered "churches", but rather that they are ecclesial communities or "specific faith-believing communities" because their ordinances, doctrines, are not historically the same as the Catholic sacraments and dogmas, and the Protestant communities have no sacramental/ministerial priesthood, and therefore lack true apostolic succession.

Contrary to how the Protestant reformers were often characterized, the concept of a catholic or universal Church was not brushed aside during the Protestant Reformation. On the contrary, the visible unity of the Catholic Church was an important and essential doctrine of the Reformation. The Magisterial Reformers, such as Martin Luther, John Calvin, and Ulrich Zwingli, believed that they were "reforming" the Catholic Church, which they viewed as having become corrupted. Each of them took very seriously the charges of schism and innovation, denying these charges and maintaining that it was the Catholic Church that had left them. In order to justify their departure from the Catholic Church, Protestants often posited a new argument, saying that there was no real visible Church with divine authority, only a "spiritual", "invisible", and "hidden" church— this notion began in the early days of the Protestant Reformation.

Wherever the Magisterial Reformation, which received support from the ruling authorities, took place, the result was a reformed national Protestant church envisioned to be a part of the whole "invisible church", but disagreeing, in certain important points of doctrine and doctrine-linked practice, with what had until then been considered the normative reference point on such matters, namely the Papacy and central authority of the Catholic Church. The Reformed churches thus believed in some form of Catholicity, founded on their doctrines of the five solas and a visible ecclesiastical organization based on the 14th and 15th century Conciliar movement, rejecting the Papacy and Papal Infallibility in favor of Ecumenical councils, but rejecting the latest ecumenical council, the Council of Trent. Religious unity therefore became not one of doctrine and identity, but one of invisible character, wherein the unity was one of faith in Jesus Christ, not common identity, doctrine, belief, and collaborative action.

Today there is a growing movement of Protestants, especially of the Reformed tradition, that reject the designation "Protestant" because of its negative "anti-catholic" connotations, preferring the designation "Reformed", "Evangelical" or even "Reformed Catholic" expressive of what they call a "Reformed Catholicity" and defending their arguments from the traditional Protestant Confessions.
