Justin Martyr (died c. 165 C.E.) in his “Dialogue With Trypho, a Jew” (XLIX), used the expression “it is written” when quoting from Matthew, in the same way the Gospels themselves do when referring to the Hebrew Scriptures. The same is also true in an earlier anonymous work, “The Epistle of Barnabas” (IV). Justin Martyr in “The First Apology” (LXVI, LXVII) calls the “memoirs of the apostles” “Gospels.”​—The Ante-Nicene Fathers, Vol. I, pp. 220, 139, 185, 186.

Revelation, also rejected by some, was attested to by many early commentators, including Papias, Justin Martyr, Melito, and Irenaeus.
