Muslims would say Christ is not God and there is no such thing as a Triune God. This is mostly because they do not understand it. Well, just because you fully do not understand it, does not mean it is proof that it is not true.
To Alpha - My friend you bring a point about faith. You say that Muslims do not believe that Christ is not God because they do not understand it and so it is not enough that it is fake. This is what you believe in and you are entitled fully to your faith. I commend your stand for your faith.
However, God cannot be beaten and crucified by His Creations. It is far above Him to be judged when He is the Ultimate Judge, it is far above his to be mocked at when He know what ye hide and ye reveal. Jesus (may peace be upon him) was a great man and one of the greatest to walk the face of earth, but he delivered a message from God to show man to the straight path. You may still say that I do not understand it because I am a Muslim, but so be it. Yet you look at the crosses all over America and watch Jesus, or God, hang with a crown head as blood trickles from his side where man's spear pierced the side of God. Tell me my friend where is the Glory of God? He loves us this i know, and you wills say that God did that becasue He loved us, but is he not The All mighty and All powerful. Why do we destroy His Grace and call it love? Are you worshipping God or the messenger of God, when it should have been worhsip God and listen to the messengers words of Truth. As for the Trinity, I can only say "Say not that God is part of Trinity for He is One."
