Having grown up in a traditional Jewish synagogue, I can tell you that if you preached the name of Jesus you would probably be thrown out, possibly even spit on. Rabbis are still very fearful of the idea of Jesus being the Christ. To them it means giving up their traditions and what they have known for their entire lives. They still need the gospel preached to them though. The messianic synagogue is a good medium for them, since they still hold the values and important traditions of Jewish people, but with Yeshua Hamashiach (Jesus the Messiah) at the center of it all. Like all denominations, they don't have perfect theology, but are still accepted, loved, and used by God.
I hope this all helps, ask anything else if you'd like me to clarify =)
Thanks so much for your insight! One thing we learned about Judaism in relgious studies is that they tend to live in concentrated neighbourhoods. Orthodox Jews have to live as close to the synagogue as possible since they can't drive their cars on that Sabbath, because that would involve lighting a fire, if they take a cab they have to prearrange it because they can't do buisness on the sabbath* and if they choose to walk, they can't go very far since they can only take so many steps on the Sabbath. Anyway, where I grew up there were no practicing Jews that I knew of, but here I'm right on the edge of the Jewish district. Furthermore, my boss and lots of my co-workers and clients are Jewish. So for that reason I've been doing a lot of research on Judiaism. I'll be in the Kosher aisle at the grocery store and then the next day at work I'll be like "What does 'Kosher for Passover' mean? I mean other than it can't have baking soda."
Anyway, I got this great book from the library called "Tough Qeustions Jews Ask" by Rabbi Edward Feinstein. He answers the question about what is Christianity. I was very, very surprised to see that his description of Christianity was pretty accurate. On the other hand, they have a lot respect for education,** something I really respect about them, so I guess they'd really want what they wrote to be accurate.
Anyway, he says "The truth is that we never rejected Jesus. We just have different ideas about God and human beings... For Christianity, sin is something we
are. For Judaism, sin is something we
do. Judaism does not believe in a permanent gap between God and us. We beleive that whenever we choose evil, we can undo the damage. This is the Jewish idea of
Teshuva, which means 'turning' or 'changing.' Judaism teaches that we can always transform ourselves and bring ourselves back into harmony with God." [emphasis in the original]
Then later when he answers the question "Can a person be half-Jewish, half-Christian" he says no, because you either believe in
Teshuva or you believe in Jesus. He's absolutely right.
Teshuva is incompatible with what the New Testament teaches relying on Jesus means.
So basically that means that Messianic Jews reject the doctrine of
Teshuva in favour of
Yeshua.
*Although this confuses me because my avoids shopping, getting gas, taking cabs, going to the library, going to the movies etc on Sunday because that would involve having someone work for her on the Sabbath, and in the 10 Commandments we're told to not let servants work for us. Exodus 20:10 says "but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, neither you, nor your son or daughter, nor your manservant or maidservant, nor your animals, nor the alien within your gates."
**I bet this is why they've won so many Nobel prizes. The guy who studied what makes people sucessful says that somone with a supiror (120) IQ has the same chances of winning a Nobel prize as someone who is off the charts briliant, because it has more to do with work than intellect.
