Papias
Matthew
also issued a written Gospel among the Hebrews in their own dialect, while Peter and Paul were preaching in Rome and laying the foundation of the Church. After their departure, Mark, the disciple and interpreter of Peter, did also hand down to us in writing what had been preached by Peter. Luke also, the companion of Paul, recorded in a book the Gospel preached by him. Afterwards John, the disciple of the Lord, who also had leaned upon his breast, did himself publish a Gospel during his residence at Ephesus in Asia. (Against Heresies, 3:1)
Irenaeus was a student of Polycarp, who was a student of the Apostle John. Around 170 A.D., Irenaeus confirms and elaborates upon Papias’ report:
In Papias’s writings, known as
Expositions of the Oracles of the Lord, it is stated by Eusebius of Caesarea, that he wrote: ‘
So then Matthew wrote the oracles in the Hebrew language,
and every one interpreted them as he was able’ (in Eusebius,
Church History,
3.39.16). Papias lived within 50 years after the death and resurrection of Christ.
The Bishop Papia of Hierapolis said:
"Matthew gathered Jesus's loghia in a Hebrew dialect and each of them translated them (in Greek)
Origen
Among the four Gospels, which are the only indisputable ones in the Church of God under heaven, I have learned by tradition
that the first was written by Matthew, who was once a publican, but afterwards an apostle of Jesus Christ,
and it was prepared for the converts from Judaism and published in the Hebrew language. (Recorded by Eusebius in Church History, 6:25)
Eusebius
For Matthew, who had at first preached to the Hebrews, when he was about to go to other peoples,
committed his Gospel to writing in his native tongue, and thus compensated those whom he was obliged to leave for the loss of his presence. (Eusebius, Church History, 3:24)
Jerome (374-420 A.D.) who saw the Hebrew gospel, said he had translated it and on several occasions and he quoted from it (
On Famous Men 2 & 3).
