My major problem with Christian doctrine is the idea that they use the Hebrew Bible to justify Jesus as the Messiah. If you look at the specific requirements for a Jewish Messiah, which is what people claimed Jesus was, he did not fulfill any of those requirements. He didn't overthrow the Romans, he didn't rebuild the Temple, and he didn't bring peace to the world.
Also, the common passge in Isaiah about a "virgin" conceiving is not accurate. The Hebrew says that the child shall be born in wedlock. It doesn't have to be a virgin, just an unmarried women.
What OT verses are you reffering that lay down these "requirements"?
