c. a.d. 85
John likely wrote 1 John from Ephesus, where apparently he had relocated near the time of the fall of Jerusalem to the Romans in a.d. 70. The letter was probably intended to be read by the church in Ephesus and perhaps also by other churches in the surrounding cities. Ephesus was a wealthy and highly influential port city in the Roman province of Asia, and it was renowned for its temple of Artemis (Diana).
