GOD in His pure essence is infinite Spirit.
In the beginning and afterwards, GOD revealed Himself to man as the 'Memra'/ 'Messenger of YHVH' in an apparent human form.
In the miraculous conception of the man Jesus, the 'Memra' added literal human flesh, which was Jewish, to His person.
The 'Memra' had no beginning.
The Jewish humanity had a beginning.
The Jewish man, Jesus/Yeshua and the infinite 'Memra'/D'var/Logos
are eternally joined as one 'person'.
Yes GOD is a Jew.
"How odd of GOD to choose the Jew,
yet, not quite so odd as those who choose the Jewish GOD
but hate the Jew."-unknown author
