요한2서

2 John was written by 'the elder' (verse 1), traditionally identified as the apostle John. The letter's language, themes, and style are nearly identical to 1 John. John was an elderly church leader in Ephesus when he wrote this brief letter around 85-95 AD, addressing it to 'the elect lady and her children' — likely a house church.

2 John is the shortest book in the Bible by word count, containing just 1 chapter with 13 verses. Despite its brevity, it addresses the crucial topics of walking in truth and love, and warns against showing hospitality to false teachers who deny Christ's incarnation.

The main theme of 2 John is the balance between truth and love. John commends walking in truth and loving one another (verses 4-6), while warning that love must not compromise truth — specifically, false teachers who deny that Jesus Christ came in the flesh must not be welcomed into the community (verses 7-11).

Key teachings include: the command to 'walk in truth' as the Father commanded (verse 4), the restatement of the love commandment — not a new command but one from the beginning (verses 5-6), the warning against deceivers 'who do not acknowledge Jesus Christ as coming in the flesh' (verse 7), the danger of losing what has been accomplished (verse 8), and the refusal to welcome false teachers (verses 10-11).

2 John demonstrates that Christian love is not permissive tolerance but discerning commitment to truth. The letter addresses a tension relevant to every church: how to be loving and welcoming while protecting the community from destructive teaching. John's warning provides biblical warrant for maintaining doctrinal boundaries as an act of love toward the community.
