The Epistle to the Ephesians is one of the letters in the New Testament by Paul. It stands out for its lofty theology, emphasizing God’s cosmic plan in Christ, the unity of Jews and Gentiles in the church (one new humanity), and practical exhortations for Christian living in household relationships and spiritual warfare. Most scholars believe that Ephesians was written by Paul during his first Roman imprisonment (c. AD 60–62), alongside Colossians, Philemon, and Philippians (the “Prison Epistles”). It was delivered by a man named Tychicus.

First Century Ephesus was a major metropolitan center in the Roman province of Asia (modern western Turkey). With a population estimated at 250,000, it was one of the empire’s largest cities after Rome and Alexandria. Ephesus was a prosperous port city, a commercial hub at the end of major trade routes, and a center of learning and culture. It was most famous for the Temple of Artemis (one of the Seven Wonders of the Ancient World) and as a stronghold of pagan worship and sexual rites, with significant economic ties to idol-making (as seen in the riot in Acts 19). The city featured impressive Roman architecture, including a massive theater (seating ~25,000, site of the Artemis riot), libraries, baths, agoras, and aqueducts. Paul came there initially as a substitute for a well-regarded preacher named Apollos. The Ephesus church, despite Apollos preaching, was tiny—just twelve men. Paul baptized the group in the name of Jesus and the Holy Spirit fell upon them, changing the character of Ephesus.

Paul ministered there extensively during his third missionary journey (c. AD 52–55), spending over two years teaching daily in the hall of Tyrannus (Acts 19). This led to widespread conversions and some conflict, culminating in a riot led by silversmiths fearing loss of trade from Artemis shrines. This riot led to Paul’s Ephesus becoming a key early Christian center, later associated with the Apostle John and addressed in Revelation 2:1–7.

Ephesians core themes—our identity in Christ, reconciliation of Jews and Gentiles through Christ, the church as Christ’s body and God’s temple, and ethical living amid a pagan culture—fit the multi-ethnic church in Ephesus and surrounding areas, as well as the multi-cultural, post- Christendom context of today.
