Iagree with you about where Yahshua would be the most comfortable and that would be on a hillside teaching, however He did attend synagogue every Sabbath as all good Jews did. He was never acused of being a bad Jew. I believe Jesus/Yahsua is the Messiah of Israel. I believe He is the only begotten son of Elohim (God/generic name). I believe He is God and fully God, part of the Trinity.
Deuteronomy 6:4 tell us that Adonai Elohaynu is echad (one)
composite one, not yachid (one) indivisible one. Says it all.
When was the Trinity formed and how many other Gods are there?
