When does the Catholic Church officially refer to herself as the Roman Catholic Church?
Wiki:
The name "Catholic Church" has been used on official documents such as the title of the
Catechism of the Catholic Church. It is also the term that
Paul VI used when signing the sixteen documents of the Second Vatican Council. However, Church documents produced by both the Holy See and by certain national
episcopal conferences occasionally refer to the Church by the name "Roman Catholic Church". The Catechism of Pope Pius X published in 1908 also used the term "Roman" to distinguish the Catholic Church from other Christian communities.
Also, what are the earliest usages of the term "Roman Catholic Church"?
Wiki:
The term
Roman Catholic appeared in the
English language at the beginning of the 17th century, to differentiate specific groups of
Christians in communion with the
Pope from others; comparable terms in other languages already existed. It has continued to be widely used in the English language ever since, although its usage has changed over the centuries.
