Gospel of Mark - 58-65 AD, written by a disciple of Peter
quotes from Papias on the Gospel of Mark in Hist. Eccl. iii. 39:
For information on these points, we can merely refer our readers to the books themselves; but now, to the extracts already made, we shall add, as being a matter of primary importance, a tradition regarding Mark who wrote the Gospel, which he [Papias] has given in the following words: “And the presbyter said this. Mark having become the interpreter of Peter, wrote down accurately whatsoever he remembered. It was not, however, in exact order that he related the sayings or deeds of Christ. For he neither heard the Lord nor accompanied Him. But afterwards, as I said, he accompanied Peter, who accommodated his instructions to the necessities [of his hearers], but with no intention of giving a regular narrative of the Lord’s sayings. Wherefore Mark made no mistake in thus writing some things as he remembered them. For of one thing he took especial care, not to omit anything he had heard, and not to put anything fictitious into the statements.”
Irenaeus wrote (Against Heresies 3.1.1): “After their departure [of Peter and Paul from earth], Mark, the disciple and interpreter of Peter, did also hand down to us in writing what had been preached by Peter.”
There are some other pieces of* external* evidence that show that the author of the Gospel of Mark was a disciple of Peter:
Justin Martyr quotes from Mark as being the memoirs of Peter (Dial. 106.3). In Acts 10:34-40, Peter’s speech serves as a good summary of the Gospel of Mark, “beginning in Galilee after the baptism that John preached.” Finally, there was not an extremely strong motivation for the early church to attribute the second gospel to one obscure Mark, the disciple of Peter, instead of directly to an apostle. Thus, the tradition of Markan authorship is to be taken seriously.
