سقوط الإمبراطورية الرومانية الغربية
While the "Roman Church" has been used to describe the pope's Diocese of Rome since the Fall of the Western Roman Empire and into the Early Middle Ages (6th–10th century), the "Roman Catholic Church" has been applied to the whole church in the English language since the Protestant Reformation in the late 16th century. "Roman Catholic" has occasionally appeared also in documents produced both by the Holy See, notably applied to certain national episcopal conferences, and local dioceses.
