Most evangelicals identify the author of Ephesians 1:7 as the Apostle Paul. Below is a concise, evangelical-oriented summary about him and why he’s regarded as the writer of this verse and the letter.

Text of the verse (ESV): “In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace.”

Who Paul was (short bio)
– Born Saul of Tarsus, a Jewish Pharisee and Roman citizen (Acts 22:3, 22:25–29).
– Persecuted the early church until his conversion on the road to Damascus (Acts 9).
– Called by Christ to be an apostle, especially to the Gentiles (Acts, Galatians, Romans).
– Traveled on multiple missionary journeys, planted churches across Asia Minor and Greece, and wrote several New Testament letters.
– Traditionally imprisoned in Rome around AD 60–62; many evangelicals date Ephesians to that Roman imprisonment.

Why evangelicals attribute Ephesians to Paul
– Internal claim: The letter opens, “Paul, an apostle of Christ Jesus…” (Ephesians 1:1), an explicit self-identification.
– Early church testimony: The early church consistently attributed Ephesians to Paul.
– Theological continuity: Major themes in Ephesians—salvation by grace, union with Christ, the church as Christ’s body, redemption and forgiveness—fit squarely with Paul’s theology as found in his other letters.
– Historical context: The letter’s style, vocabulary, and its presentation as a circular letter to the Asian churches are explained by evangelicals as variations of Paul’s diction, possible use of an amanuensis (secretary), and different pastoral/theological purpose, not proof of pseudonymity.

How Ephesians 1:7 fits Paul’s theology
– Redemption through Christ’s blood: echoes Paul’s central teaching that Christ’s death secures our salvation (cf. Romans, Galatians).
– Forgiveness of trespasses: ties to justification and reconciliation themes that shape Paul’s gospel.
– “According to the riches of his grace”: emphasizes grace (not works) as the source of salvation—a hallmark of Pauline doctrine.
– The verse expresses assurance, hope, and the objective work of Christ—consistent with Paul’s pastoral aims.

Practical and pastoral significance (evangelical emphasis)
– Assurance: Believers can be confident in forgiveness and redemption that rest on Christ’s finished work.
– Gospel-centered life: Gratitude and holy living flow from awareness of Christ’s grace and purchase.
– Unity and identity: Redemption and forgiveness define the church’s identity and mission, themes Paul stresses elsewhere in this epistle.

A brief note on scholarly debate
– Some critical scholars argue for a non-Pauline or pseudonymous authorship based on style and vocabulary. Evangelicals typically maintain Pauline authorship, arguing that differences reflect occasion, rhetorical strategy, theological development, or editorial practice rather than forgery.
