This has all the hallmarks of a troll, but my asnwer, nonetheless:
IMO, you don't have to refute the ideals and faith of judiasm to accept christ's teachings...i don't think you can be faithful to some of the traditions that have grown to be a part of the religion, eg: kosher. but if you look to the summations of the message of judiasm that the rabbis would identify in scripture, they are the same good news that Jesus proclaimed. Love God, love one another... Now, this formulation obviously has a great deal of commentary, but the concept at the core is that God has been the one who has loved steadfastly (hesed), acted to redeem and rescue (go'el) and has sought justice (halakah) . God seeks for these same actions and values to be a part of the lives humankind. reading the parables...i find the exact same teachings.
Pardon any errors in the hebrew, but those are the transliterations i remember...
My final witicism is that those boundaries mean nothing to one who is truely one with God, for as the Apostle Paul writes, "there is no Jew or Greek, slave or free, male or female, all are one in Christ Jesus."
