Which book defends Paul's authority and status as an apostle?

• A. 2 Corinthians
• B. Galatians
• C. Romans
• D. Colossians

Answer: (A)

The key idea here is recognizing where Paul makes his case for being an authoritative messenger of Christ. In this book, Paul confronts critics of his ministry directly and lays out a clear, personal defense of his apostolic calling. He insists that his authority comes from Christ and God, not from human approval, and he points to concrete demonstrations of his role—his sufferings, hardships, and the genuine results of his ministry—as evidence that he is indeed commissioned as an apostle. This focus on validating his appointment and leadership within the church is why this book stands out as the best fit for defending Paul’s authority and status as an apostle. While another letter also touches on his status, its primary aim is different (arguing for the gospel’s message rather than chiefly defending his office), and the others are more doctrinal in nature.
