If I am not a Jew Christ cannot be my savior?
Was Handel's Messiah only written for a Jewish audience?
Jesus changed the rules for everyone. He brought a new way. Trying to go back and make it all Hebrew again is fallacy at its best.
You can call on His NAME I don't know the answer to your question. Yah'shua started the New Covenant But then again you may be one of those NO
shalom b'SHEM Yah'shua HaMashiach
as He outlined Jer 31:31-37.
that believe that Jesus is another god
who changed all the rules and started
a new religion.
Well you are partially correct once again.
Jesus is God, who created a new covenant, changing the rules as it were, and came as the Messiah for the whole world, both the Jews and everyone else (a twofer from God) he did start a new Religion, Christianity, built off of both traditions old and new.
It is not one that requires us to make numerous revisions to our own version of the Bible, say a name perfectly that we are not sure of the pronunciation to begin with nor is it simply traditional Judaism just add Savior that showed up in 1920.
