The apostle Paul wrote this intensely personal and biographical letter to defend his ministry and integrity against the slanderous attacks of false teachers and critics of the Christian movement.

But back in Corinth, false teachers began to infiltrate the church, and they were intent on ruining Paul’s character and ministry. This threatened to separate and create chaos among this once-unified body.
