The document discusses St. Paul's Letter to the Ephesians and debates its authorship. While some argue Paul wrote it himself, others believe it was composed after Paul's death by a follower, due to differences in vocabulary, style, and theology compared to Paul's undisputed letters. The letter's intended audience and location are also uncertain. It may have been intended for churches in a wide region, rather than just Ephesus, and aims to establish unity and peace in the universal church.
