It’s mostly terms like, “Romanist,” etc. that have a hate-filled history.
HOWEVER, the name of the communion is the Catholic Church. “Roman” is not in the official name and may refer to many different matters:
1. The Latin Patriarchate. By referring to the entire communion as “Roman,” there is an implicit denial of the universality of the Church, as if the Latin Patriarchate is in isolation, as if the Bishop of Rome is in disunity with the rest of the catholic Church.
2. Headquartered in Rome. The emphasis on “Roman” is often used by Protestants to connect the Catholic Church to the Whore Babylon. This fooled even Martin Luther who claimed to have visited the Vatican as the basis for his innumerable Satanic slanders: The Vatican is not in Rome; it’s across the river in the Vatican City, where the Bishop of Rome has served in exile form the city of worldly power.
3. Because of many duplicitous heretical movements, such as the Polish Catholic Church, the Old Catholic Church, the Ultrecht Catholic Church, etc., the Catholic Church in America frequently identifies itself as the Roman Catholic Church, to signify those individual congregations or diocese which are in faithful union with the Bishop of Rome. This is the reason for most of your exhibits. The qualifier shouldn’t be necessary.
4. Some very early Catholic writers refer to the Roman, Catholic Church. In this instance, the usage is to assert the unity and structural integrity of the Church hierarchy throughout the “Roman world,” which was viewed as synonymous with all of civilization. This is not a name, per se, and reflects a colloquial usage of “Roman,” despite the establishment of Catholic congregations far beyond the borders of Rome.
Churches have split apart because of a number of differences but to state that martin luther’s assertions about the catholic church were “satanic” is extremely offensive and unnecessary.
