While the term "Roman Catholic Church", in its most literal sense, means the Church of Rome, the ecclesiastical jurisdiction in Rome, it is also used to refer to the whole Christian Church in communion with the Bishop of Rome.
It has been used in this sense even by Popes.
While the term "Roman Catholic Church" thus does appear with this meaning in official documents of the Church in question, the term "Catholic Church" is used much more frequently than "Roman Catholic Church" in this sense.
The term "Roman Catholic Church" appears repeatedly in the sense of the whole Christian Church in communion with the Bishop of Rome (not just the Church in Rome alone) in official documents concerning dialogue with other Christians. Examples of such documents can be found at the links on the Vatican website under the heading Pontifical Council for Promoting Christian Unity
