“Sorry.
The Jews who followed Yah’shua
did not believe in three gods or a trinity.
That was a later Greek thing codified and
promulgated by the Roman “church”
with the development of Dogma in the form of creeds.
shalom b’SHEM Yah’shua HaMashiach”
The doctrine of the trinity is not just the doctrine of the New Testament, but also of the Old. Daniel’s vision of the Messiah coming to the “Ancient of Days” and receiving power and dominion forever and ever, including worship. Isaiah writing “And now the LORD God, and His Spirit, hath sent me” is another. The scripture is certainly there.
Yah'shua said: Again Eisegesis !
shalom b'SHEM Yah'shua HaMashiach John 10:30 "I and the Father are one."
The words Father, Son and Spirit
are all metaphors for YHvH.
