Galatians 2 introduces the key vocabulary and theological ideas around which the entire letter revolves. For many years, and largely because of the interpretation of the Protestant Reformers, many saw the central question of Galatians as 'how does a sinner gracious God'? This position has been very strongly challenged, and many argue that this was the Reformers' question and not Paul's; a view which I am largely sympathetic with. As we shall see in this episode, the key underlying question of Galatians is about ethnic unity in view of the Resurrection. Paul's question is not, 'how do I find a gracious God', at least not in the initial instance; rather his question is, 'how can Jewish believers and gentile believers be one family - the children of Abraham and the New Covenant people of God.
