Ephesians (c.60–62 CE or later) explores the nature and unity of the Church as the body of Christ. It discusses believers’ position 'in Christ', the unity between Jews and Gentiles, and includes exhortations on Christian living and the 'armor of God' for spiritual warfare.

Author: Traditionally Paul (some question authorship, but the letter states Paul).

Date Written: Circa 60–62 CE (though some argue later, early 90s CE based on style).

Context: Possibly written to the church in Ephesus (or circulated among churches), Ephesians addresses a community thriving in Asia Minor, encouraging unity and reminding Gentile believers of their place in God’s redemptive plan.
