The author identifies himself as John, historically considered to be the Apostle John, who also wrote the Gospel of John along with I John, II John and the Book of Revelation. Liberal theologians disagree, conceding only that all three epistles were likely written by the same person.
John wrote this book to:
- Greet Gaius.
- Thank Gaius for his good work.
- Tell that Diotrephes was living badly.
- Tell all Christians to be like other good people.
Language and Style
Like the rest of the New Testament, III John is written in Koine Greek. It was originally written as a letter. John only addresses himself as "the elder", because when he wrote III John church leaders were called elders. As in II John, he writes that he does not want to write all he wants to tell in a letter. This may explain the small size of III John.
