I hear all the talk about the Qur'an and Muslims saying Christ is just a prophet.

The Messiah must be descended on his father's side from King David (see Genesis 49:10 and Isaiah 11:1). According to the Christian claim that Jesus was the product of a virgin birth, he had no father -- and thus could not have possibly fulfilled the messianic requirement of being descended on his father's side from King David!

The Christian idea of a virgin birth is derived from the verse in Isaiah 7:14 describing an "alma" as giving birth. The word "alma" has always meant a young woman, but Christian theologians came centuries later and translated it as "virgin." This accords Jesus' birth with the first century pagan idea of mortals being impregnated by gods.

***********************************

The Catholic idea of Trinity breaks God into three separate beings: The Father, the Son and the Holy Ghost (Matthew 28:19).

Contrast this to the Shema, the basis of Jewish belief: "Hear O Israel, the Lord our God, the Lord is ONE" (Deut. 6:4). Jews declare the Shema every day, while writing it on doorposts (Mezuzah), and binding it to the hand and head (Tefillin). This statement of God's One-ness is the first words a Jewish child is taught to say, and the last words uttered before a Jew dies.

In Jewish law, worship of a three-part god is considered idolatry -- one of the three cardinal sins that a Jew should rather give up his life than transgress. This explains why during the Inquisitions and throughout history, Jews gave up their lives rather than convert.

******************************

Judaism does not demand that everyone convert to the religion. The Torah of Moses is a truth for all humanity, whether Jewish or not. King Solomon asked God to heed the prayers of non-Jews who come to the Holy Temple (Kings I 8:41-43). The prophet Isaiah refers to the Temple as a "House for all nations."

The Temple service during Sukkot featured 70 bull offerings, corresponding to the 70 nations of the world. The Talmud says that if the Romans would have realized how much benefit they were getting from the Temple, they'd never have destroyed it.

Jews have never actively sought converts to Judaism because the Torah prescribes a righteous path for gentiles to follow, known as the "Seven Laws of Noah." Maimonides explains that any human being who faithfully observes these basic moral laws earns a proper place in heaven.
