"No one teaches us the Oral Torah, therefore how can we accept or deny it? "

Are you refering to Jews or Gentiles? There are more Jews learning Talmud now than ever before in the history of the world (except for Sinai itself). The Talmud is accessable on books, tapes, CDs, online, etc. I agree with Naftali thatit is best to learn with a teacher or study partner. But, there are even free telephone programs where a Jew can learn with a partner.

"Can G_d be working thru Yeshua? Well, he worked thru Balaam." Absolutely right. I've learned more about Judaism that I ever expected while trying to explain to others why Jews don't accept Jesus. (Btw, the analogy to Balaam is great--the Talmud makes a similar analogy using Balaam's name while possibly discussing Jesus).
