In Course TH215, Trinitarian Theology, a learning objective for segment 1 is "describe how Jewish monotheism indicated a plurality within the Godhead"
In segment 1, it states, "They were monotheists, and some of the Jews—already before the Christian era—believed that there was some kind of plurality within the Godhead. They would read passages from the ot and see that there was an angel of Yahweh who was identified in some way with Yahweh but also somehow differentiated from Yahweh."
Can someone from Logos (or this forum) please provide the source for this teaching? I cannot find it in this course. Thank you.
