Here is the blurb from Amazon about his thesis:
Hansen argues that unity formula employed in “Gal 3.28”, “1 Cor 12.13” and “Col 3.11” offers equality between competing social groups. Hansen argues against prevalent views that the unity formula employed in “Gal 3.28”, “1 Cor 12.13” and “Col 3.11” reflects either a Hellenistic anthropology of ideal androgyny or a modern liberal conception of social equality. Rather, Hansen contends, attention to function and context demonstrates each epistle’s vision of social unity. Insights from ethnic theory elucidate how the epistles characterize this unity in terms of a new social identity, and the practices warranted by that identity. Furthermore, Hansen claims that because identity construction is continual, dynamic and discursive, alternate identities (e.g. ethnic, gender, religious, economic) within the new Christian communities, may be seen as influencing one another and may be termed as the collective Christian identity. Hansen employs theories from Ethnic study as tools for assessing how such overlapping identities persist and interact with one another. His analysis thereby demonstrates that the social unity promoted by this formula opposes cultural dominance by any particular group and, conversely reinforces the persistence of marginal social identities within new communities. The issue is then not one of gender equality, but of the equality that Paul wishes to develop between competing social groups.
