Duh...
Nooooooooooooooo they dont...
The Christians believe in God the Father, God the Son, and God the Holy Spirit...
And the Moslems believe?
The same as the Jews.
Christians also believe in one God;however,they believe that there are three persons in God.
It seems all three monotheistic religions believe in the same God. In all cases that God is the Creator,He is transcendent and He is omniscient,omnipotent and omnipresent.
If one wanted to argue,one could say the one God of the Jews is more similar to the one God of the Moslems than to the Triune God of Christianity.
