In this book, four views are offered in this topic of Paul: Reformed (by Thomas R. Schreiner), Catholic (by Luke Timothy Johnson), Post-New Perspective (by Douglas A. Campbell), and Jewish (by Mark D. Nanos).
In reading the synoptic gospels over and again, then reading James, and then the Pauline letters, I was struck at how different they were. Something was wrong. Either Paul is wrong on what faith is or, we’re reading him wrongly.
In James chapter 2:14-24, James combats a teaching that has emerged in the Church. The teaching was known as “sola fide“. It taught that people were justified, or made righteous, by “faith alone“. It’s a belief that teaches faith (mental assent) doesn’t need works (acts of obedience). This was predominantly Paul’s gospel, and made popular by the Reformers about 1500 years later.
