Westfall's claim that Galatians is about 'cultural conflicts, dynamics of power, and law vs. liberty'

Westfall claims the purpose of Galatians is 'to deal with cultural conflicts, the dynamics of power, and the tension between law and liberty.' Mike responds: (1) 'Cultural conflicts' is vague and unhelpful — Galatians addresses very specific conflicts, not cultural conflicts in general. (2) 'Dynamics of power' is simply not in Galatians — you could only see it through a critical theory or feminism lens. (3) 'Tension between law and liberty' is somewhat accurate but imprecise. Galatians is about justification, the method of salvation, and the benefits of salvation.
