The term Roman Catholic is sometimes used to differentiate the Catholic Church and its members in full communion with the pope in Rome from other Christians who identify as "Catholic". It is also sometimes used to differentiate adherents to the Latin Church and its use of the Roman Rite from Catholics of the Eastern Catholic Churches. It is not the official name preferred by the Holy See or bishops in full communion with the pope as a designation for their faith or institution.
The term "catholic" is one of the Four Marks of the Church set out in the Nicene Creed, a statement of belief widely accepted across Christian denominations. Catholics, Eastern Orthodox, and Oriental Orthodox consider the term "Catholic" to refer to a single institutional one true church, while Protestant ecclesiology considers it to refer to a church invisible referred to as the Christian Church. The use of "Roman" or "Roman Catholic" to differentiate the Catholic Church dates from the Middle Ages.
In Christian theology, ecclesiology is the study of the Church, the origins of Christianity, its relationship to Jesus, its role in salvation, its polity, its discipline, its eschatology, and its leadership.
In its early history, one of the Church's primary ecclesiological issues had to do with the status of Gentile members in what had become the New Testament fulfilment of the essentially Jewish Old Testament church. It later contended with such questions as whether it was to be governed by a council of presbyters or a single bishop, how much authority the bishop of Rome had over other major bishops, the role of the Church in the world, whether salvation was possible outside of the institution of the Church, the relationship between the Church and the State, and questions of theology and liturgy and other issues. Ecclesiology may be used in the specific sense of a particular church or denomination's character, self-described or otherwise. This is the sense of the word in such phrases as Catholic ecclesiology, Protestant ecclesiology, and ecumenical ecclesiology.
