Most scholars consider Papias to be mistaken or misunderstood. We have no manuscripts whatsoever of Matthew in Hebrew.
We also have the testimony of Irenaeus;
"
Matthew also issued a written Gospel among the Hebrews in their own dialect, while Peter and Paul were preaching at Rome, and laying the foundations 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 the Heretics, Book III, ch.1)
Then we have 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. (In Eusebius in
Church History, 6:25)
And, Eusebius himself
"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)
Surely they all can't be wrong, even though we don't have a manuscript for this as yet? This early witness seems quite strong.
