Was the Gospel of John written by John the Baptist?
It's a bit hard to write a Gospel when your heads sitting on a plate, separate from your body.
In reality we don't know precisely who the authors were, but assume they were written by apostles or their followers, bearing the name of the Gospels.
The "The Lion Handbook to the Bible" had this to say ...
"The author (who may, like Paul, have used a secretary) refers to himself simply as 'the disciple whom Jesus loved' (21:20,24). He is one of the Twelve, and one of those closest to Jesus and also to Peter. These facts - and the fact that this Gospel makes no mention of the apostle John and describes the Baptist simply as 'John', make it likely that he is himself John, son of Zebedee, brother of James, and business partner of Peter and Andrew. The early church certainly thought so - and taught that the aged apostle wrote or dictated this 'spiritual' Gospel from Ephesus in present-day Turkey. John may have been Jesus' cousin (his mother, Salome, being Mary's sister: Matthew 27:56, Mark 15:40; John 19:25).
The Capernaum fishing business must have been a flourishing one, as the household had hired servants, and a house in Jerusalem. If the 'other disciple' of 8:15-16 is John it may have been through the business that John was acquainted with the high priest (John 18:15-16). He may also be the unnamed disciple of John the Baptist referred to in John 1:35, 40.
John and James (nicknamed by Jesus 'sons of thunder') with Peter were the leaders of the Twelve Disciples and later of the Jerusalem church. They were the inner circle of three who were allowed to see Jesus transfigured, who saw him restore Jairus' daughter to life, and were near him in the Garden of Gethsemene. Jesus committed his own mother to John's care as they stood near the cross. It was not given to many to know Jesus as closely as John did."
