John: In the majority viewpoint, it is unlikely that John the Apostle wrote the Gospel of John.[113][114] Rather than a plain account of Jesus' ministry, the gospel is a deeply meditated representation of Jesus' character and teachings, making direct apostolic authorship unlikely.[115] Opinion, however, is widely divided on this issue and there is no widespread consensus.[116][117] Many scholars believe that the "beloved disciple" is a person who heard and followed Jesus, and the gospel of John is based heavily on the witness of this "beloved disciple."[118]
Most scholars date the Gospel of John to c. 80–95.[54][119]
