The gospel promoted by Paul has for many generations stirred passionate debate. That gospel proclaimed equal salvific access to Jews and gentiles alike. But on what basis? In making sense of such a remarkable step forward in religious history, Jason Staples reexamines texts that have proven thoroughly resistant to easy comprehension. He traces Paul's inclusive theology to a hidden strand of thinking in the earlier story of Israel. Postexilic southern Judah, he argues, did not simply appropriate the identity of the fallen northern kingdom of Israel. Instead, Judah maintained a notion of 'Israel' as referring both to the north and the ongoing reality of a broad, pan-Israelite sensibility to which the descendants of both ancient kingdoms belonged. Paul's concomitant belief was that northern Israel's exile meant assimilation among the nations – effectively a people's death – and that its restoration paradoxically required gentile inclusion to resurrect a greater 'Israel' from the dead.

In this book, Jason A. Staples proposes a new paradigm for how the biblical concept of Israel developed in Early Judaism and how that concept impacted Jewish apocalyptic hopes for restoration after the Babylonian Exile. Challenging conventional assumptions about Israelite identity in antiquity, his argument is based on a close analysis of a vast corpus of biblical and other early Jewish literature and material evidence. Staples demonstrates that continued aspirations for Israel's restoration in the context of diaspora and imperial domination remained central to Jewish conceptions of Israelite identity throughout the final centuries before Christianity and even into the early part of the Common Era. He also shows that Israelite identity was more diverse in antiquity than is typically appreciated in modern scholarship. His book lays the groundwork for a better understanding of the so-called 'parting of the ways' between Judaism and Christianity and how earliest Christianity itself grew out of hopes for Israel's restoration.
