James McGrath, author of The Only True God: Early Christian Monotheism in Its Jewish Context contends that the Apostle Paul would have agreed with the Shema, which is not anything new for anyone in the Messianic Movement. However what is Paul doing in 1 Corinthians 8.6 “yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist.” One blogger asks is Paul adding Jesus as a “second power” to the Shema? Is this where Jewish monotheism was left by the early disciples of Yeshua and a new Christian monotheism started?
Here is an abstract of McGrath’s article that argues for Paul’s Orthodox Jewish commitment coming through clearly as he wrote what later became part of the New Testament:
Using as an example Paul’s interpretation of Scripture in connection with the topics of monotheism and Christology, the article suggests that, in the absence of explicit and emphatic statements of the difference or distinctiveness of his views, Paul’s allusions to key monotheistic texts would have been understood to indicate Paul’s agreement with the axiom of Jewish monotheism, the Shema.
