Introduction to Galatians
Author:
The apostle Paul (Gal 1:1; 5:2; 6:11—“see what large letters I write with my own hand”). Authorship is undisputed in the early church.
Date & Conditions:
Either AD 48–49 (very early, right after the Jerusalem Council of Acts 15, the “South Galatian” theory) or AD 53–55 (during the third missionary journey, the “North Galatian” theory). Paul writes in white-hot urgency and anger—he skips his usual thanksgiving and launches straight into rebuke (1:6: “I am astonished…”).
False teachers (Judaizers) had infiltrated the churches he planted in Galatia, teaching that Gentile believers must be circumcised and keep the Mosaic law to be truly saved. Paul sees this as “another gospel” that strikes at the heart of justification by faith alone.
Original Audience:
Predominantly Gentile churches in the Roman province of Galatia (cities like Pisidian Antioch, Iconium, Lystra, Derbe—Acts 13–14). These young believers were being pressured to add Jewish law to their faith in Christ.
Purpose in one sentence:
To defend the true gospel of justification by faith apart from works of the law, to expose the false teachers, and to call the Galatians back to the freedom they received when they first believed.
Key line: “A man is not justified by the works of the law but by faith in Jesus Christ” (2:16).
Introduction to Ephesians
Author:
The apostle Paul (Eph 1:1; 3:1). Though some modern scholars question this, the early church universally accepted Pauline authorship, and the letter’s style, theology, and personal details match Paul perfectly.Date & Conditions: AD 60–62, written from prison in Rome (3:1; 4:1; 6:20) at the same time as Colossians, Philippians, and Philemon (the “Prison Epistles”). Paul had spent nearly three years in Ephesus (Acts 19), but he is now chained and sends this letter via Tychicus (6:21–22). The tone is soaring, worshipful, and majestic—no specific crisis is addressed.
Original Audience:
Primarily Gentile believers in Ephesus and the surrounding churches in Asia Minor (the phrase “in Ephesus” is missing in the two oldest manuscripts, suggesting it may have been a circular letter). These were mature churches that had already received deep teaching from Paul himself.Purpose in one sentence: To lift the church’s eyes to the cosmic dimensions of God’s eternal plan—how Jew and Gentile are now one new humanity in Christ, seated with Him in the heavenly places—and to show how that heavenly identity must transform everyday life, relationships, and spiritual warfare.
Key line:
“Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places” (1:3).
In short:
Galatians = Paul’s fiery defense of the gospel of grace: “We are saved by faith alone!”
Ephesians = Paul’s worshipful hymn of the gospel of glory: “We are already seated with Christ—now live like it!”
