2 Corinthians

The second letter to the Corinthians was written by Paul in the same year as the first, around 55 AD, and this letter indicates that it was written from Macedonia. The main topic is about Paul establishing his credentials as having authority from Jesus, against accusers among the Corinthians. Paul will state clearly that his authority is not to command but to build up. None of his critics could claim better or closer faithfulness to the teachings of Jesus.
