According to the recent findings of qualified exegetes of Saint John (i.e. Fr Feuillet, Fr Braun, Fr Spicq) the Gospel of John was written at a very late date. It was the last revealed book. In all Bibles, The Book of Revelation is placed at the end. It is not the Revelation that completes the Bible, but the "Gospel of John". (...) Saint John was in no hurry to write. I think he didn't even want to write - and that is understandable. When we experience certain things, when we have had such close ties to someone - like the relationship between Jesus and John - we don't really feel like writing about it. And of course, John could not write: "I am the beloved disciple" during the lifetime of the other Apostles. This wouldn't have been very considerate to the others. It is more than likely that John met Luke, who was an intellectual and an artist, a man with a very fine intelligence. Luke wrote perfect Greek, while on the other hand John's Greek was much more tentative. So John met Luke; Luke was able to write all that John communicated to him. This friendship between John and Luke always reminds me of the relationship that God worked between Moses and Aaron at the time of Moses' vocation. When God sent Moses to Pharaoh to bring the people of Israel out of Egypt, Moses was afraid and he immediately found a good excuse: "Please, my Lord, I have never been eloquent." And God answered him: "There is your brother Aaron the Levite, is there not? I know that he is a good speaker" (Ex 4: 10 & 13). Moses was inspired and Aaron spoke. God loves matching up his instruments. Isn't there something similar in the case of Luke and John? John didn't stutter, but his love was too strong, which is a way like stuttering. So when he met Luke, John felt relieved. It was wonderful: Luke transmitted everything that John had to say, everything that Mary had told him. Moreover, this is why the Gospel of Luke is so similar to John's. Good exegetes are well aware of this dependence of Luke with respect to John.
