Internal &
External Evidence of Johannine Authorship
It is important to establish John
as the author of the Gospel bearing his name primarily for apostolic eyewitness
and authorship. This especially during a period of Gnostic influences. Köstenberger
aptly puts it this way: “John’s Gospel claims to represent apostolic eyewitness
testimony regarding Jesus’ earthly ministry.”[1] There is ample internal and external evidence
in support of Johannine authorship with John being “John, the son of Zebedee,” one of Jesus’ disciples. The internal
evidence is as follows:
·
The author is identified in Jn. 13:23 as “the
disciple whom Jesus loved.” That he is “the disciple whom Jesus loved” is also
mentioned in 21:2, 23, and stated as the “one who “testified to these things
and wrote them down” (21:24). The author also has close connections to Peter
and part of Jesus’ inner circle (Lk. 5:8-10,8:51; Mk. 3:16-17, 5:37; Mat.
17:1-2). Of noteworthy mention is the visit to Jesus’ tomb on Resurrection
Sunday, where the author is identified as “the one whom Jesus loved” (20:1-8).
