2 John

Second John is the shortest book in the New Testament, written by one who identifies himself simply as 'the Elder,' widely understood to be the apostle John in his later years. The letter is addressed to 'the elect lady and her children,' a phrase most scholars interpret as referring to a local church and its members rather than a literal woman. Written likely from Ephesus near the close of the first century, the letter reflects a community navigating the challenges of early false teaching, particularly a proto-Gnostic denial of Christ's incarnation.

The letter's twin pillars are love and truth, themes John insists cannot be separated in genuine Christian life. Walking in love means obeying God's commandments as the community has been taught from the beginning. Walking in truth means holding firmly to the confession that Jesus Christ has come in the flesh, and refusing to extend hospitality to those who spread doctrines that undermine this confession. John's warm pastoral concern shines through as he encourages the congregation to guard what they have received, reminding them that protecting sound doctrine is itself an act of love for the whole body of Christ.
