Problem: Please summarize: Luke Timothy Johnson critiques Thomas R. Schreiner's essay for its emphasis on the fulfillment of Scripture, individualistic portrayal of sin, narrow view of the cross, and interpretation of pistis Christou. Johnson advocates for a more nuanced understanding based on rigorous exegesis, pointing out selectivity and deficiencies in Schreiner's reading when examined against the entirety of Paul's correspondence. In response to Thomas R. Schreiner, Mark D. Nanos critiques Schreiner's ideological and selective approach to Paul's theology.

Nanos challenges Schreiner's views on Galatians, questioning the accuracy of Schreiner's portrayal of Paul's opponents. He points out discrepancies in Schreiner's interpretations, highlighting methodological issues, and urges a more nuanced consideration of Paul's writings, emphasizing the need for historical and exegetical precision over theological presuppositions.
