Smiddy3,
Research the origin of Yahweh.
Research how the Hebrews had monotheism imposed upon them by the minority that could write. (Isaiah 40ff was largely written by these monotheists. Deuteronomy was also a creation of that 7th to 6th century BCE period.).
Research Second Temple Judaism to see its direct impact on New Testament thinking.
As a thought: The name "Immanuel" invokes the "EL", the name of the main God that the Hebrews adopted from the Canaanites (along with his wife Asherah and their 70 sons, including Baal).
It's all mythology built on top of other mythologies.
Paul's ideas about Jesus are more reflective of the earlier views, and are some 50 years earlier than the ideas created by the writers of "John's" Gospel.
