New Testament

2 John

Second John is a brief letter from 'the elder' to 'the chosen lady and her children' (), urging them to keep walking in truth and love and to refuse hospitality to traveling teachers who deny that Jesus Christ came in the flesh. It is one of the shortest books in the Bible. It belongs in Scripture because it shows that love and truth belong together: love obeys God's commands, and truth about Christ sets limits on what love may support.

Author: 'The elder' (1:1), traditionally the apostle John in old age. Early writers also mention a 'John the elder' in Asia, and scholars debate whether he was the apostle or a different leader, but the letter's language is clearly close to 1 John and John's Gospel.
Audience: 'The chosen lady and her children' (1:1), most likely a local church and its members described in personal terms, with her 'elect sister' (1:13) a sister church. Some read it as addressed to an individual Christian woman and her family.
When: Probably about the same time as 1 John, in the late first century, around AD 85–100.
Where: Not stated. Tradition places the elder in or near Ephesus, writing to a church in the surrounding region of Asia.
Genre: Second John is a real personal letter, short enough to fit on a single sheet of papyrus, following the standard ancient pattern of sender, recipient, greeting, body and farewell. Read it as a pastoral note that applies the larger teaching of 1 John to a concrete practical question: whom should a house church welcome and support?

Shape of the book

Greeting in Truth and Love · ch 1Verses 1–3: The elder greets the chosen lady and her children, whom he loves in the truth, with grace, mercy and peace from the Father and the Son.
Walk in Truth and Love · ch 1Verses 4–6: He rejoices that some are walking in the truth and renews the old command to love one another, defining love as walking in God's commands.
Guard Against Deceivers · ch 1Verses 7–11: Many deceivers deny Jesus Christ's coming in the flesh, so the church must remain in the teaching of Christ and not welcome or support those who bring a different teaching.
Hope to Meet Face to Face · ch 1Verses 12–13: The elder prefers to speak in person rather than with paper and ink, and sends greetings from the children of the elect sister.

Themes

Truth. The word truth appears five times in the first four verses. Truth is something believers love in (), know, that abides in them and will be with them forever (), and that they walk in (). For John, truth is God's reality revealed in Jesus, not only correct ideas.
Love as Obedience. The command to love one another is not new but from the beginning (). Love is then defined: walking according to His commandments (). Love and obedience explain each other.
Confessing Christ Come in the Flesh. The deceivers refuse to confess the coming of Jesus Christ in the flesh (), the same error opposed in . Denying the real humanity of the Son is called the work of the antichrist.
Remaining in the Teaching. Anyone who 'runs ahead' without remaining in the teaching of Christ does not have God, while whoever remains in it has both the Father and the Son (). Progress that leaves behind the apostolic teaching about Christ is not progress.
Hospitality With Discernment. In a world where traveling teachers depended on house churches for lodging and support, welcoming a false teacher meant sharing in his work (). Hospitality, highly valued elsewhere (), is here guided by truth.

Where Christ is

Second John is concerned with who Jesus is. It names Him 'Jesus Christ, the Son of the Father' () and makes confession of His coming in the flesh the dividing line between truth and deception. To remain in His teaching is to have both the Father and the Son ().

The Son Come in the Flesh. Fulfillment. The Word became flesh (), and 2 John treats this confession as essential. The promise of God dwelling with His people is fulfilled in the real human life of the Son. (; ; ; )
Having the Father Through the Son. Fulfillment. Whoever remains in the teaching of Christ has both the Father and the Son (), echoing Jesus' words that no one comes to the Father except through Him and that those who have seen Him have seen the Father. (; ; )
The Old Command From the Beginning. Echo. The command to love one another, which the readers have had from the beginning (), is the new command Jesus gave His disciples, itself rooted in the law's call to love one's neighbor. (; ; )

Reading well, key terms and common misreadings

Read it well

Read it right after 1 John 4:1–6. The danger in 2 John is the same false teaching about Christ, now applied to a practical decision.
Imagine the setting of traveling preachers and house churches. The instruction about not receiving someone 'into your home' (1:10) concerns giving a teacher a base and support for his ministry.
Read it alongside 3 John. One letter warns against welcoming false teachers, the other commends welcoming true ones; together they show hospitality guided by truth.

Key terms

Elder πρεσβύτερος (presbyteros) — An older man or church leader. Here it is a title the readers recognize without needing a name (1:1).
Truth ἀλήθεια (alētheia) — Reality as God reveals it, especially in Jesus (John 14:6). In 2 John truth is loved, known, abides and is walked in (1:1–4).
Deceiver πλάνος (planos) — One who leads others astray (1:7). John links the deceiver with the antichrist.
Remain, abide μένω (menō) — To stay or continue. The key contrast is between remaining in the teaching of Christ and running ahead beyond it (1:9).

Easy to misread

Using 1:10–11 to justify rudeness or refusing ordinary kindness to anyone who disagrees. The instruction concerns teachers who deny Christ come in the flesh and who would use a church's welcome to spread that teaching.
Taking 'love' in 2 John as acceptance without limits. John defines love as walking in God's commandments (1:6) and joins it inseparably to truth (1:3).
Assuming the 'chosen lady' must be an individual woman, or must be a church. Both readings have been held; the closing greeting from an 'elect sister' and her children (1:13) inclines many to see churches, but the main teaching does not depend on this.
