Whose Letter Is It

Ephesians sits at the center of one of the New Testament's most durable authorship debates. Its Greek differs from the seven undisputed Pauline letters in ways that go beyond ordinary variation, longer sentences, a distinctive vocabulary, and a more developed, universal picture of the church as a single cosmic body rather than the local congregations addressed elsewhere in Paul. It also overlaps so closely with Colossians in wording and structure that most scholars treat the two as directly related, whichever way the dependence runs. These features have persuaded a majority of critical scholars that Ephesians was written after Paul's death by a disciple working in his tradition and name, a common and, in antiquity, not necessarily dishonest literary practice; a minority of scholars, along with the whole of traditional and confessional interpretation, continue to defend direct Pauline authorship, noting that a letter addressed broadly to several churches rather than one, if Ephesians was in fact circular, would naturally read differently from Paul's occasional correspondence. The dispute is entirely about origin, not standing: no Christian tradition treats the question as bearing on the letter's canonical authority, and Ephesians remains among the most quoted New Testament texts in Christian teaching on unity, grace, and the nature of the church across every tradition that reads it.
