(a) Why Sola Scriptura is FALSE (Matt Fradd w/ Patrick Madrid)
(b) Up until the late 2nd century, no one acknowledged the canonicity of Hebrews, Acts, James, Jude, Revelation, John (1, 2, 3) and 1 and 2 Peter. Clement of Alexandria and Origen of Alexandria believed the Epistle of Barnabas as having been inspired Scripture. Justin Martyr didn’t recognize Philippians or 1 Timothy. Irenaeus of Lyons and Tertullian of Carthage believed that the Shepherd of Hermas was inspired. No Church Father got all the books right until Athanasius of Alexandria in A.D 367. That is over 300 years after Christ’s death, resurrection and ascension.
Through the Councils of Rome, Hippo and Carthage, the NT canon was officially determined and closed. At the Councils of Hippo and Carthage, which Augustine attended, the deuterocanonical books were listed as Scripture. You can even find them listed in the Codex Sinaiticus and Codex Alexandrinus. They were not separated from the other books. Almost all of the Church Fathers regarded the Septuagint as the standard form for the OT. They saw no difference between the deuterocanonical books and the other books within the OT. Irenaeus, Cyprian of Carthage, Tertullian, Gregory Nazianzus, Athanasius and Cyril of Jerusalem, for instance, cited from them as being Scripture. Jerome was the only exception to the rule and he submitted to the authority of the Catholic Church.
Adolf Harnack [Protestant, Scholar, Historian]:
“The New Testament canon . . . is primarily traceable to the Church of Rome. It has now been proved that the whole series of New Testament books in their canonical and universally accepted versions were derived from Rome. Finally, new evidence of the greatest value indicates that from the third century the versions of the West, i.e. the Roman texts of the New Testament, entered into the texts of the Oriental biblical manuscripts. These data clearly prove that the Eastern Churches corrected their own versions by comparison with the New Testament received from Rome in those days. It was with special reference to Rome that an authentic list of Bishops extending back to the Apostles was prepared” [History of Dogma [1899], German edition, vol. 1, p.443, cited in Asmussen, Hans, et al, The Unfinished Reformation, translated by Robert J. Olsen, Notre Dame, Indiana: Fides Publishers Association, 1961, 87-88].
