Cold Steel,
There is a reason I mentioned "The Annotated Jewish New Testament" and those two documents from the Vatican. These are good starting points to answer all your questions.
I made links on these materials because I expect you to see the evidence for yourself. I knew you wouldn't believe me, so I wanted to make data that verifies my claims accessible.
Don't people avoid learning about Mormonism directly out of fear sometimes? It is easier to do this for some because people fear to be proven wrong. This is what is happening here.
1 Corinthians 15:29 is not foreign to Judaism. Baptism is based on the Jewish practice of "tevilah." Converts to Judaism would engage in tevilah by immersion ( the Greek word from which "baptism" comes from) in an immersion pool or tub called a "mikveh." The experience symbolized rising from death to a new life in Judaism.
But tevilah in a mikveh is also required by Torah if one comes into contact with a dead body. One "washes away death," so to speak, by means of this.
As "The Annotated Jewish New Testament" will tell you (if you would just read it), the Greek of 1 Corinthians 15:29 can actually be rendered "washing the dead" since "baptism" literally refers to this ritual wash. While likely a play off the words and practice of Jewish ritual washing, it is not phraseology unheard of to Jews.
Mikveh is actually performed before all Jewish burials. The dead body is washed or "baptized" via tevilah. This is a proxy tevilah as the ritual must be engaged in voluntarily when alive. Therefore when a dead body undergoes tevilah via mikveh it is done by proxy, by another who "washes the dead," or baptizes you in a mikveh since you cannot. So the Mormon belief is not "new" or foreign to Jews as you claim, just given a different meaning and practiced differently by LDS.
As for what Jews expect about the Messiah, why not hear from other Jews as well. Visit JewsforJudaism.org or Aish.org for starters. You may also want to visit your local synagogue and ask those in religious education there.
Anyone following this discussion between you and I can see you have great misconceptions about Judaism and have built upon these misconceptions to build your arguments.
I go back to the OP here because the only reason you wouldn't know precisely what Judaism teaches on these subjects is that your religion doesn't allow you to be exposed to information that isn't filtered. You don't check up on these things for youself. Why not? This is out of fear. For if you just learned for yourself or read up on these things you will see that you have no sturdy foundation to stand on for your arguments. So you just keep arguing back to me here instead of looking up these things for yourself or visiting your local synagogue. Use the links and web sites I have given you. Learn from the source. Why not? Are you afraid to be proven wrong? Would you be brave enough to accept that you are?
A lot of religious people hold on to their misinformation about the Jews out of fear. You would rather argue to support your misinformed views of Judaism than stop and learn for yourself. The OP is right. It's all fear.
