------------------------ John's Gospel talks of a 'disciple whom Jesus loved' but does not identify that disciple. The second-century Church Fathers noticed that whenever the book talks about the disciple, it does not mention John and, on this evidence alone, decided that this disciple must therefore be John. Like all the New Testament Gospels, John's Gospel was written anonymously, but the Church Fathers came to the conclusion that the author must be the 'disciple whom Jesus loved' and, since they had decided this disciple to be John, the Gospel author was the disciple John. The second century reasoning was merely conjecture and is not accepted by modern biblical scholars. If the 'disciple whom Jesus loved' was closest to Jesus, we still do not know who that disciple was.
Jesus told the disciple John to take care of her.
Andrew had been a disciple of John the Baptist and was given an order from John to follow Jesus instead of him.
He was introduced to Jesus by another disciple by the name of Philip. You can find the source material in John.
The Apostle John When Jesus therefore saw His mother, and the disciple whom He loved standing by, He said to His mother, "Woman, behold your son!" Then He said to the disciple, "Behold your mother!" And from that hour that disciple took her to his own home. (NKJV) John refers to himself as the "disciple Jesus loved" several times in his gospel in order to keep the readers' focus on Jesus, and not call attention to himself.
