Short answer: most evangelical Christians identify the author of Romans 3:23–24 as the Apostle Paul.
Why Paul is identified as the author (evangelical perspective)
– The letter itself names Paul as the writer (Romans 1:1: “Paul, a servant of Christ Jesus, called to be an apostle…”). Evangelicals take this internal claim at face value as historically reliable.
– Early Christian testimony uniformly attributes Romans to Paul (e.g., church fathers like Clement, Irenaeus, and others).
– The theology, vocabulary, and style of Romans fit with Paul’s undisputed letters (e.g., Galatians, 1–2 Corinthians), especially the themes of sin, justification by faith, grace, and Christ’s redemptive work.
– Manuscript evidence: Romans appears in the earliest Greek manuscript families and in the early canonical lists used by the church.
Who Paul was (brief evangelical summary)
– Born as Saul of Tarsus, a Jew of the tribe of Benjamin and a Pharisee by training (Philippians 3:5; Acts 22:3).
– He was a Roman citizen (Acts 22:25–29), well-educated in Jewish law under Gamaliel, and initially a persecutor of the early church (Acts 8–9).
– He experienced a dramatic conversion on the road to Damascus (Acts 9), after which he became the chief missionary to the Gentiles and an authoritative teacher.
– He undertook several missionary journeys, planted churches across Asia Minor and Greece, and wrote letters to congregations and leaders addressing theology and practice.
– Tradition and early church history place his death under Nero in Rome (c. A.D. 64–68).
When and where Romans was written (standard evangelical view)
– Romans was most likely written by Paul from Corinth (or while he was in Corinth) late in his third missionary journey, commonly dated around A.D. 56–58.
– The letter was addressed to the church in Rome, a mixed Jewish–Gentile congregation Paul had not yet visited, and was carried by Phoebe from Cenchreae (Romans 16:1–2).
Why Romans 3:23–24 is significant for evangelicals
– Romans 3:23–24 expresses core evangelical convictions: all people are sinners; justification is a gift of God’s grace; redemption comes through Christ Jesus.
– This passage is frequently cited in evangelical preaching and teaching as central to the doctrine of salvation by grace through faith (cf. Romans chapters 3–5, Galatians 2:16, Ephesians 2:8–9).
Further reading (evangelical resources)
– Romans commentaries by John Stott, Douglas Moo, Leon Morris, and D. A. Carson.
