Barrett C.K. Freedom and Obligation: Study of the Epistle to the Galatians

Westminster Press, 1985. — 120 p.Solid, scholarly effort by C.K. Barrett in expounding Paul's letter to the Galatians without a commentary-sized work. Barrett is very effective at elucidating Paul's sometimes complex argumentation, as well as reconstructing the arguments of Paul's opponents from the apostle's own argumentative points.
