The Second Letter to the Corinthians is an implicit yet undeniable plea that Paul addresses to the Christians of Corinth and is impressive above all for its exposition of the apostle's identity. In this letter Paul more than once fiercely counters the attacks of his opponents. He extensively describes both the quality and circumstances of his apostolic existence: the sufferings he endures, the opposition he encounters, and his continual care for the Churches. Second Corinthians is, therefore, highly significant theologically as well as autobiographically.

Not an easy letter to follow, the emotional language used in 2 Corinthians, the question of the integrity of 2 Corinthians as a letter, and inadequate information about the concrete situation at Corinth and the identity of Paul's opponents make following the flow of Paul's argument difficult at times. Yet 2 Corinthians is an especially important document because of Paul's ongoing reflection on his ministry. It is both profound in its content and style for its original audience as well as for today's readers.
