I’ll tell the disciple/apostle John that he should have talked to you before he wrote.
I favor this position:
Point #1: The testimony of the disciples of the Apostles and the generations of disciples to follow them cannot be ignored. The earliest mention suggesting John as the writer of the fourth Gospel is found in St. Justin Martyr's First Apology (61.4). St. Justin was martyred circa 155AD. In this work he alludes to John 3:3-5 and speaks of the Gospels as including "memoirs of the Apostles", in the plural. This would have to be a reference to Matthew and John since Mark and Luke were not Apostles in the narrowest use of the word as applied to the original 12 (eleven after Judas' death), but who also came to be called "apostles" as this Greek word, which means "emissaries" was later applied to all those who held positions of leadership within the Church. Justin Martyr's testimony is very important because Ephesus was his home church and he would have been very familiar with anything his great Apostle-bishop had written and the traditions associated with John's writings.
Point #2: Probably the most important second century testimony concerning the authorship of the fourth Gospel comes from St. Irenaeus Bishop of Lyon (b. 140AD, m. 202AD). Irenaeus was the disciple of St. Polycarp, Bishop of Smyrna who was a disciple of John the Apostle. Irenaeus, in his work Against Heresies, briefly describes the composition of and authorship of the four Gospels and records that after the first three were written "John, the disciple of our Lord, who also had leaned upon his breast, did himself publish a Gospel during his residence at Ephesus in Asia." (Against Heresies 3.1.1). Later in the same work St. Irenaeus quotes verses from the fourth Gospel and attributes the words to "John, the disciple of the Lord."
Point #3: During Irenaeus' lifetime the Church was working to discern which writings should become the New Testament Canon. The oldest list that has survived is known as the Muratorian Fragment, named for the scholar of discovered it, I.A. Muratori who published the manuscript in 1740. Authorship of this document has been variously attributed to Caius of Rome, Hegesippus (first Church historian), Clement of Alexandria, Bishop Melito of Sardes, Bishop Polycrates of Ephesus, and possible Bishop Hippolytus of Rome, who like Irenaeus was a disciple of Polycarp, who was a disciple of St. John. The document contains an account of the writing of the fourth Gospel: "The fourth Gospel is by John, one of the disciples. When his fellow disciples and bishops were urging him, he said, 'Fast with me for three days beginning today, and whatever will have been revealed to us, let us recount it with each other.' On that very night it was revealed to the Apostle Andrew that all the things they had recalled to mind, John should write them all in his own name. And therefore while various points are taught in the different books of the Gospels, there is not difference to the faith of believers; for in all of them all things are spoken under the one guiding Spirit, ..."(Faith of the Early Fathers, vol. I, page 107).
but I believe they would know more of who was there in the previous generation. I know who my great grandmother was/is than someone deciding 2,000 years later.
