Name a New Testament letter written by Paul and its main theme.

• A. Romans — justification by faith.
• B. Romans — the supremacy of the Old Covenant.
• C. Galatians — salvation by works.
• D. Philippians — Christian hospitality.

Answer: (A)

Paul’s letters often teach that people are made right with God through faith in Jesus, not by earning it through works. In the book of Romans, that idea is the main thread: justification by faith. It explains that God’s righteousness is received by trusting in Christ, uniting Jews and Gentiles in the same gospel. This helps you see why this option fits best: it names a letter written by Paul and highlights a core theme he emphasizes there.

The other options don’t align as tightly with the strongest theme of the respective books. The notion of the Old Covenant as supreme isn’t the main focus of Romans, where Paul argues that righteousness comes through faith rather than reliance on the law. Galatians centers more on freedom from the law and the danger of turning back to relying on works for salvation, rather than presenting “salvation by works” as its primary message. Philippians is known for themes of joy, partnership, and living out faith, with hospitality mentioned but not treated as its main theme.
