A local Council of the Church (actually two) the Council of Carthage and the Council of Rome, and the Pope, Pope Damascus I. It was compiled from the Scriptures that were read at Mass, see the links below.
When the Gnostic Gospels came in the 2nd Century, the Church needed to find out which books belong in the Bible. So the Church form the Councils that listed OT, plus the 27 NT books.
Though collections of sacred writings, varying in extent, existed in the various local Churches of Christendom, the canon or official list of Scripture was only compiled by the Church toward the end of the fourth century-at Hippo in 393, Carthage in 397, whence it was sent to Rome for confirmation in 419. The Bible may be called the notebook of the Church, and she has always claimed to be the guardian, exponent, and interpreter of it. . . .
By these Councils, the Bible we see today came into be. These Councils are Catholic. How do we know? Well, St. Ignatius of Antioch called the Christian Church Catholic. Let me quote him, “Where there is Jesus Christ, there is the Catholic Church.” (Wherever the bishop shall appear, there let the multitude [of the people] also be; even as, wherever Jesus Christ is, there is the Catholic Church)
