The book of Galatians is a Pauline Epistle (letter from Paul). It was written by the Apostle Paul about 49 A.D. prior to the Jerusalem Council which had taken place in 50 A.D. This quite possibly could have been Paul’s first letter. The key personalities of this book are the Apostle Paul, Peter, Barnabas, Abraham, Titus, and false teachers. Paul writes this book to deal with the problem of circumcision and Jewish legalism toward Gentile believers.
