Which letter highlights Paul's confidence that he is an authentic apostle despite critics?

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

Answer: (D)

Paul’s confidence as a true apostle, despite critics, is most clearly shown in the letter to the Corinthians. In this writing, he directly defends his calling, arguing that apostleship comes from God’s calling and the gospel revealed to him, not from human approval. He points to the concrete signs and wonders God performed through him, along with the hardships and persecutions he endured for the gospel, as evidence that his ministry is genuine. By contrasting his credentials with those of rival teachers and embracing his weaknesses as moments where God’s power shines, he demonstrates that his authority doesn’t depend on outward opinion but on divine commissioning and faithful gospel work. This explicit defense against critics and emphasis on divine validation make this letter the best fit for highlighting his authentic apostleship.
