This article will examine and critique Douglas Campbell's account of the proper grounds for Christian ethics in light of his exegesis and interpretation of Gal 3:28. It will do so by raising three difficulties for his proposal. First, a close reading of his argument will show that as it stands it suffers from a lack of internal coherence. Second, it will show that Campbell's project is best understood as a restriction of the sources for ethical belief formation and then argue that this restriction leaves the ethicist with insufficient resources for constructive ethical reflection. Finally, it will show that his reading of Gal 3:28 shows considerable tension with the development of his thought in his recent essay, “Apocalyptic Epistemology” and also appears to be incompatible with traditional accounts of the incarnation. Inasmuch as Campbell's proposal reflects a number of common trajectories in contemporary studies of Pauline ethics—a turn toward eschatology, a suspicion of “natural theology,” and an emphasis on the liberational elements of Paul's gospel—the conclusions of this article have salient implications for future studies in Pauline ethics, particularly on the continuities and discontinuities between the categories of our lived existence and their relation to our identity in Christ.
