John, The Second and Third Epistles of

The Second and Third Epistles of John are the shortest books in the New Testament, each occupying a single papyrus sheet. Both are written by "the Elder" (Greek ho presbyteros), widely identified with the apostle John. Second John is addressed to "the elect lady and her children," most likely a metaphor for a local church and its members. Its central concern is the same as First John: false teachers who deny that Jesus Christ has come in the flesh must not be received into one's home or given a greeting that could be construed as endorsing their teaching (2 John 7–10). Third John is addressed to Gaius, a church member commended for his hospitality to traveling missionaries. The letter rebukes Diotrephes, who refuses to receive the Elder's authority and expels those who show hospitality to the brethren, and commends Demetrius. Together these brief letters illuminate the dynamics of authority, hospitality, and doctrinal discipline in early second-generation Christianity.
