While reading up on a topic, I came across the following quotes:
The original meaning of the first
verse [of the Shema] may have been that, unlike the pagan gods who have different
guises and localities, God is one. (Louis Jacobs, “Shema, Reading of,” Encyclopedia
Judaica, 18:455)
For Stoics, the manifold gods
worshipped as different beings are all manifestations of one divine power. (Lori
Ann Robinson Baron, "The Shema in John's Gospel Against its
Backgrounds in Second Temple Judaism," PhD diss., Duke University, 2015,
122)
Such reminded me of Jerry Grover’s and Brant Gardner’s exegesis of
Mosiah 15 and Alma 11 and their Mesoamerican context:
Jerry D. Grover on the Mesoamerican Context for Mosiah 15:1-5
The Mesoamerican Theological Background of Alma 11:28-29 and other like-texts
On Mosiah 15 and the question of whether it teaches Modalism (spoiler alert: it doesn't), apart from the above, see my discussion of this and other passages in the following interview:
