Westfall's claim: Galatians indicates 'similar scope of change' needed in culture, social practices, and authority structure

Westfall argues that when Paul parallels the three pairs (Jew/Greek, slave/free, male/female), he indicates that 'a similar scope of change in the culture, social practices, and authority structure of the church needs to be implemented to abolish entitlement and discrimination.' Mike notes this language sounds appealing — who wouldn't want to abolish entitlement and discrimination? — but Paul doesn't use these words. He is offering sonship status, not an overarching abolishment of differences in human relationships.
