Context: Galatians is the "Magna Carta of Christian freedom" — one of Paul's most passionate and urgent writings. Written to the churches of Galatia (~48–55 AD), it responds to an acute crisis: "Judaizers" had arrived after Paul teaching that converted Gentiles must be circumcised and keep the Law of Moses to be fully saved.

The confrontation: Paul begins without greetings — he goes straight to the point: "I am astonished that you are so quickly deserting" (1:6). The letter includes the narrative of the direct confrontation with Peter in Antioch (ch. 2) — a scene of extraordinary apostolic frankness that Paul narrates publicly. Justification by faith alone is affirmed with full force: "a person is not justified by works of the law but through faith in Jesus Christ" (2:16).

Theology of freedom: Chapter 3 uses Abraham to demonstrate that faith was always the principle of justification — the Law was added later as a "guardian" until Christ (3:24). Chapter 4 uses the allegory of Hagar and Sarah — slavery vs. freedom. Chapter 5 celebrates: "For freedom Christ has set us free" — freedom that is not license but service through love. The fruit of the Spirit (5:22–23) is the counterpoint to the works of the flesh.
