I’m working through key elements of Galatians 3 & 4 tonight and drawing in some material from Romans and elsewhere. My main topic will be to look at Paul’s use of the word “law” in these passages. My main references other than the Bible text will be Galatians: A Participatory Study Guide pp. 43-47 and Meditations on the Letters of Paul, Chapter VIII, pp. 89-97
Here’s a sample:
No Jew would deny the wisdom of Torah, or disavow its validity. Neither did Paul. When arguing for the universality of God’s promise to Abraham, and that all those who like Abraham have faith in God are justified before God, Paul asks rhetorically, “Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law” (Rom. 3:31). For that to be the case, Paul must have in mind more than one way of seeing the authority of the law, or the way it functions. (p. 92)
The chapter in Herold Weiss’s book (Meditations) is one of the most helpful presentations I’ve found on this subject.
