Analyzing the general framework of monotheism and its historical development (macro-analysis) equips us with a framework within which to analyze the ideologies and patterns of particular monotheistic groups (historical and modern; micro-analysis).
We will often emphasize fundamental and extremist movements because of their literal interpretations of text and theology.
The loss and subsequent desire for "national" identity, including a political authority and land as tangible confirmation, provided the catalyst for the unifying and absolute "language" of the monotheistic identity of the Judean returnees. It was unifying because it sought to establish clear, communal (and presumably social and political) boundaries in a relatively chaotic and ambiguous context. It invoked notions of the absolute in order to articulate its own distinction and claim to the land and authority above the other competitors. The language of empire facilitated this strategy. Yahweh was promoted from national god to god whose power extended over the known world and beyond immediate political boundaries.
Early monotheistic identity in Judah was a result of imperial conquest and a "return" of exiled Judeans, who redefined Judean political identity in terms of their own experiences.
Ezra-Nehemiah's prohibition on intermarriage reflected a deep concern for establishing and regulating community boundaries (cf. Neh. 13:23-27).
Example:
The "law" in Ezra-Nehemiah was intended to fashion (note constructivist and not descriptive) the social-political order into one consistent with golah collective desire for land and authority.
Three pillars of monotheism:
Concepts of an exclusive God did not produce a monotheistic religion. The desire for exclusive authority and control over the land produced the idea of an exclusive God.
