[Jael]

If you read the Qur'an's description of Allah, and read the Bible's description of God, it becomes obvious you are reading about two different persons. Allah orders his followers to kill those who deny Islam, while God instructs us to love our enemies. Allah had no son while God sent His Son to die for sinful men. Allah is "unknowable" while God seeks a personal relationship with His creation, man.

The spirit behind Islam is an entirely different spirit... a spirit that denies the deity of Jesus Christ. Any Christian who accepts the notion that Allah is God creates an impossible situation. Since the Qur'an contains our only revelation about Allah, they will be forced to look there as their authority. The Qur'an specifically denies the deity of Christ!

[Angelus Errare]

"If you read the Qur'an's description of Allah, and read the Bible's description of God, it becomes obvious you are reading about two different persons."

And a Manichean or a Gnostic would say that it is obvious that the God of the Old Testament cannot be the loving Christ of the New Testament. While I think that Muslims are extremely wrong-headed in their perception of the Deity, I don't see this as preventing them from worshipping Yahweh anymore than it stops contemporary Jews.

"Allah had no son while God sent His Son to die for sinful men. Allah is 'unknowable' while God seeks a personal relationship with His creation, man."

You do realize that these same invectives can be leveled at the Jewish faith, right?

"The spirit behind Islam is an entirely different spirit... a spirit that denies the deity of Jesus Christ."

As does Judaism. So is Judaism then irredeemably evil (as opposed to simply being incorrect)?

"Any Christian who accepts the notion that Allah is God creates an impossible situation."

Funny, the Copts have been around for over a millennium now and they're still around.

"The Qur'an specifically denies the deity of Christ!"

As does the Jewish Talmud, if I recall correctly. Your point being?

"Jehovah is not Allah. Jehovah never was the moon god Allah."

Allah simply means "the God" in Arabic. Any attempt to link it back to Arabian polytheism is ultimately an exercise of deceptive semantics. Deus, the Latin word from which we derive the term Deity, originally referred to the Greek god Zeus. So the dilemma you find yourself is this: are Coptic, Maronite, Chaldean, or Syriac Christians praying to Yahweh when they say "Allah" every day in their prayers or not?
