In John's Gospel, Jesus told "the disciple whom Jesus loved" to care for his mother, Mary, and told his mother, this is your son. We do not know who "the disciple whom Jesus loved" was, but a tradition beginning in the second century is that this was John. This instruction is missing from the synoptic gospels, where the disciple was not present at the crucifixion.

According to the Holy Bible, the disciple whom Jesus specially loved, was John, but He chose them all - even Judas!

This refers to John (later writer of the Gospel of John), who was the youngest disciple.

------------------------

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.
