Definition: The word "Roman Catholic" is a title given to the Church in Europe that refers to its teachings, beliefs, practices, liturgies, sacraments, ceremonies, rituals, prayers, prayer services, etc., as well as its doctrines, values, and organizational structure. It was introduced by Pope Gregory XIII in 1582. The term "Roman Catholicism" is used for the Church of Rome or the Church of Europe as a whole. This term has been historically used to refer to a specific group of people who share a common belief system and believe that they are members of the same faith community, often referring to Protestantism in North America. The word "Catholic" is derived from the Latin "catholicus," which means "the people" or "the Church." The term "Roman Catholicism" generally refers to the broader denomination of Catholicism within a specific geographic region or religious group. This could include the United States, Canada, Australia, New Zealand, and parts of Europe. The word "Catholicism" is often used in connection with the historical period of the early Church, as well as its modern interpretation today. It refers to the belief that the Catholic Church, a denomination within the Christian tradition, should have authority over all matters concerning religion, morality, and the like. This implies that the Church has the right to interpret religious texts, make decisions about church affairs, and interpret sacred texts. The word "Catholicism" is not the same as "Roman Catholicism." The term "Catholicism" refers specifically to the doctrine of the Roman Catholic Church, while "Roman Catholicism" encompasses the broader denomination within which it was formed.
