Take a look at this link.
After President Amadinejads speech i Geneva, it is obvious that He dont believe in the God of Jacob, the God of Israel.
But how can it be that the Vatican say that Roman Catholics believe in the same God as the Muslims?
When the Vatican expresses that their God is the same God as the God in Islam, they do not believe in the same God as Jews and Christians. Islam do certainly not believe in God of the Bible. Jews and Christians might disagree up on who the Messiah is. But they agree that God of the Bible is the God of Abraham, Isaac and Israel.
Tell people the truth.
