The name of the Church is not R. Catholic or Roman Catholic. It is just plain "Catholic."
The Church was simply called “My Church (ekklesia)” by Christ. It may have been called “Catholic” (katholikos, universal) to distinguish it from the the heresies that developed within the lifetime of the Apostles. Ignatius of Antioch writes the term in A.D. 107 as if it were already well known. “Where the bishop appears, there let the people be, just as where Jesus Christ is, there is the Catholic Church” Letter to the Smyrnaeans.
What Protestants call “the Apocrypha,” Catholics call Scripture. These books were all canonized beginning in A.D. 382 at the Council of Rome, confirmed at the Councils of Hippo (393) Carthage (397, 419), and approved by Pope Innocent I in 405. Maccabees is as canonical as Matthew or Isaiah.
The term “deuterocanon” was first used by Sixtus of Sienna in 1566 to distinguish these writings from the “protocanon” of the Hebrew Bible and non-canonical writings.
There has never been a gathering of Protestants to establish a canon. How could there be, with thousands of splinters and no authority?
Protestants owe their truncated, 66-book Bible to Martin Luther, who rejected Tobit, Judith, Wisdom, Ecclesiasticus, Baruch, I and II Maccabees, and parts of Esther and Daniel. He also rejected Hebrews, James, Jude, and Revelation but his followers restored them to their rightful place in the NT in the17th century. Unfortunately, Luther’s cuts to the OT were allowed to stand.
Deuterocanon literally means “second canon” but there was no second canon. The term simply indicates those writings that gained general acceptance in all the local branches of the Church later than the other accepted writings. The NT “deuterocanon” are Hebrews, James, II Peter, II and III John, Revelation, and Mark 16:9-20.
