If you mean that Judaism inspired Christianity and all its bizarre offshoots, well, I guess you got me there!
Christianity is the next chapter in the religion of Judaism. Christians believe that Jesus is the Messiah that the prophets spoke of.
Per the New Testament, Jesus Christ is the end of prophecy. There is and will be, only one Christ.
any religion that claims that another is Christ, whether it's Joseph Smith, a priest, Haile Selassie, Jim jones, whoever, is not a Christian religion. they may claim it all they want to, but that doesn't make it so.
