“…the Pontifical Biblical Commission was formally established by Pope Leo XIII in 1902, and in 1907, in
Praestantia Sacrae Scripturae, Pope Pius X declared its decisions to be binding.”
“8) **On the Author, Date of Composition, and Historical Truth of the Gospel According to St. Matthew, 1911. **
Matthew, the Commission said, is in truth the author of the Gospel published under his name. The Gospel was originally written in Hebrew, sometime before the destruction of Jerusalem. We cannot accept the idea that the book was merely a collection of sayings compiled by an anonymous author. While the book was first written in Hebrew, the Greek is regarded as canonical, and is to be regarded as historically true, including the infancy narratives, and passages relating to the primacy of Peter (16:17-19) and to the Apostles’ profession of faith in the divinity of Christ (14:33).
“9)
On the Author, Time of Composition, and Historical Truth of the Gospels According to St. Mark and St. Luke, 1912.
The Commission upheld the authorship of these books by Mark and Luke, their historicity, and their having been written before the destruction of Jerusalem. It cannot prudently be called into question, the Commission said, that Mark wrote according to the preaching of Peter, or that Luke followed the preaching of Paul. Both of them told what they had learned from “eminently trustworthy witnesses.”
In fact, the PBC in the 1964 Instruction warned that “There are others who have as their starting-point a wrong notion of faith, taking it that faith is indifferent to historical truth, and is indeed incompatible with it. Others practically deny a priori the historical value and character of the documents of revelation. Others finally there are who on the one hand underestimate the authority which the Apostles had as witnesses of Christ, and the office and influence which they wielded in the primitive community, whilst on the other hand they overestimate the creative capacity of the community itself. All these aberrations are not only opposed to Catholic doctrine, but are also devoid of any scientific foundation, and are foreign to the genuine principles of the historical method.”
Eusebius in
Ecclesiastical History, gives evidence that it was known in his day that Matthew wrote his Gospel in Hebrew. Eusebius himself had quoted other writers, Papias (Book III, Chapter 39, page 127), Irenæus (Book V, Chapter 8, page 187), Origen (Book VI, Chapter 25, page 245), and Eusebius himself (Book III, Chapter 24, page 108).

Even Adolf von Harnack, a rationalist historian of high repute among Rationalist and Protestants, wrote that the Synoptic Gospels were written before 70 A.D. – before the fall of Jerusalem, and accepted the tradition that St Luke derived his information on the infancy of Jesus from Mary His Mother.
