The Jewish soul does not easily accept prohibited ‘strange worship’. Most Jews who claim to be Christian do not believe in the dogmas of classical Christianity, something even Christians understood until the past generation or two.
When someone says they are a Jewish Christian, I frankly disbelieve them without lengthy investigation. Perhaps they mistakenly believe they are Jewish, or perhaps they wish to assimilate and do not wish to be honest about their true beliefs. Sure, it happens that a Jew actually believes in classical Christianity, but it is much more rare than a non-Jew converting to Judaism.
Jesus had the same problem, when he was on earth..The Pharisee’s thought he came with a *Strange Message* they looked at Jesus as a Jew who was just strange, because they were not looking for what he brought to Israel.....
They were looking for a *Warrior* from GOD who would free them from Roman Opression, they were not looking for a Messiah that brought love...They were still under the impression that the warrior in GOD could defeat Israel’s enemies, and free her from captivity....However Jesus said *Love* is going to free you, take that message to the Gentiles...That confused them...
