A thoroughly exegetical discussion and application of Paul's letter to the Galatian churches. The interpretation is theologically conservative and closely follows the historical-grammatical hermeneutic. Attention is paid to Calvinistic and Dispensational perspectives. Paul's argument against faith plus obedience is unfolded and related to ancient and modern versions of the Galatian heresy. Paul's use of his Galatian argument in later letters is explained.
