In reading literature on early Jewish and Christian monotheism (and especially the latter), I frequently run across attempts to reconcile ideas about other divinities with statements of God’s oneness by imposing a strict monotheistic rubric on the texts that then necessitates some kind of tricky ontological rationalization. The most explicit example I can think of is from Hurtado’s essay on first-century Jewish monotheism (published here and here; I will cite the latter). In it he argues for an inductive approach to evaluating monotheism (113):
The first methodological point to emphasize is the importance of proceeding inductively in forming and using analytical categories such as “monotheism.” On both sides of the issue (to varying degrees among individual studies) there has been a tendency to proceed deductively from a priori presumptions of what “monotheism” must mean, instead of building up a view inductively from the evidence of the thought and practice of ancient Jews (and earliest Christians). It is mistaken to assume that we can evaluate ancient Jewish texts and beliefs in terms of whether or how closely they meet our own preconceived idea of “pure” monotheism.
He goes on to state that we have to let self-identification determine who was monotheistic (114):
If we are to avoid a priori definitions and the imposition of our own theological judgments, we have no choice but to accept as monotheism the religion of those who profess to be monotheists, however much their religion varies and may seem “complicated” with other beings in addition to the one God.
The words “monotheism” and “monotheist,” however, did not exist during the Greco-Roman period. They first appear in philosophical treatises of the seventeenth century CE. We will never find an ancient Jewish or Christian text in which an author explicitly professes to be a “monotheist.” In order to identify “monotheism” in antiquity we have no choice but to retroject into the texts, to some degree, our own definitions of what a monotheist is. Hurtado does exactly this, but observe a qualification (114):
our policy should be to take people as monotheistic if that is what they profess to be, in spite of what we might be inclined to regard at first as anomalies in their beliefs and religious practices.
Basically, any ostensible claim to monotheism (based on “one God” language, presumably) will overrule any potential preclusion of it (such as might problematize a modern claim to monotheism). As an example, Hurtado highlights 1 Cor 8:4–6, which he asserts uses “monotheistic language” while at the same time “accommodating devotion to Christ in terms and actions characteristically deemed by them as otherwise reserved for God.”
I suggest that Hurtado is here allowing the ostensible presence of monotheism in 1 Cor 8:4–6, which he identifies based on vernacular today considered monotheistic, to govern his interpretation of the explicit acknowledgment of a divine being other than God. In other words, of the two apparently conflicting concepts, he is using monotheism as the constant or the reference point, and deciding how devotion to Christ should be understood in relation to it. But the statement “there is no other God but one” may not have meant to the author of Corinthians what it means to believers today. Ulrich Mauser made this very point twenty years ago:
It is my thesis that the Biblical insistence on the oneness of God is so different from the monotheistic consciousness of our time that the almost universal procedure of reading the Bible through the spectacles of a modern monotheist must result in a serious misreading of its message” (“One God Alone: A Pillar of Biblical Theology,” Princeton Seminary Bulletin 12.3 : 257, emphasis in original).
I suggest that Hurtado’s approach shackles the text and only lets it use “one God” language to mean what it means to us today. What would be the outcome if we were to turn the tables and seek a way to understand the language of 1 Cor 8:4–6 not in light of modern monotheism, but in light of devotion to a being other than God? Instead of asking how Christ can be worshipped and how there can be many that are “called gods” in light of the fact that the text is monotheistic, let us ask how the author can say there is only one God in light of the fact that Christ is worshipped and there are many that are “called gods.” This allows us to define their view of God’s oneness according to the text, rather than presuppose it and then try to fit their view of God’s plurality into that presupposition. After all, it’s monotheism we’re looking to define, isn’t it?
