New Testament writers have proposed their theories on Paul's antagonists in the Epistle to the Galatians. This book was published as these scholars excluded the persecution of Christianity. The contents comprise this past conflict between Judaism and Christianity. The second part contains the three main views of the Galatia opponents: Judaizers, Antinomians, and Jewish Christian Gnostic. It concludes with the author's identification of the opponents and their message to the Churches in Galatia. Anyone studying Galatians would benefit from this writer's view of these opponents. The book was written by pastors, students, and professors at local seminaries. I hope that many of the New Testament writers with the views on the opponents read this copy. The identity of the Galatia opponents determines the correct interpretation of Paul's epistle. Christians can defend the Gospel against their opponents. It further provides a practical application of Scriptures.
