Muslims Are Infidels Who Believe In A Different God
It isn't difficult.
For a Christian, Christ is God and the Holy Spirit is God.
If anyone says that the God of the Muslims is the same god than God, he denies both the divinity of Christ and the divinity of the Holy Ghost. One can only hope that this unfortunate person simply does not know what he is talking about, because otherwise his punishment will be, if he dies unrepentant, both fearful and eternal.
As a Christian, I cannot agree with a Muslim that he believes in the same god as we do. I can concede to him that, in his misguided ignorance and wrong belief, he thinks that he believes in the same God. I will, with prudence and charity, make him aware of his fateful mistake, which is exactly why Christians properly call Muslims infidels. But I will never, ever, as a Christian, state that his is a right statement.
We only need to read the Athanasian Creed to fully understand the enormity of the blasphemy of equiparating in any way the false god of the Muslim to God.
We cannot in any way downplay the Trinity without denying it. We cannot pretend to momentarily forget both the Son and the Holy Ghost because the Father bears, it would appear, some resemblance to the false god of the Muslims.
And in this Trinity none is afore or after Other, None is greater or less than Another, but the whole Three Persons are Co-eternal together, and Co-equal. So that in all things, as is aforesaid, the Unity in Trinity, and the Trinity in Unity, is to be worshipped. He therefore that will be saved, must thus think of the Trinity.
The Three Persons are Co-Equal. The Son and the Holy Ghost are just as great as the Father. They aren't appendices of a father who would, then, be the most important part, and the same for both religions. If there is no place for Son and Holy Ghost, clearly there can never be the same Father. We can't just ignore two of the Persons, distort the third up to the point of making it unrecognisable, and make an equivalence with an imposture. It would be like saying that Muslims have the same traffic lights we have even if they have no use of both the amber and the green, which they consider both evil. In fact, in that case not only the traffic lights would be different, but even the red would have a different nature and function.
I could go on with this until tomorrow morning, as Christ as Lord (that is: as God) is so much an integral part of Christianity that every attempt to deny it and maintain the deity of Islam as the same god must seem absurd at every step. I believe that God became man and died to redeem us. They think it an unpardonable sin to believe exactly the same thing. How on earth can anyone think that we believe in the same God? How can a god be the same as God, whose believers maintain that he “has no son?”
Then let us look at our beliefs and theirs. The Mohammedans believe in a grotesquely sensual heaven, in which the elect, erm, go at it the whole time with dozens of women, eat like pigs and and drink like fish (yes, they drink too!), and are surrounded by servants and untold luxury all the time. How on earth can this be the same god as the Christian one? This is a deity for goat-rapists, drunkards, gluttons and slave drivers, bearing no resemblance to God.
Again, one can go on ad infinitum. However, I will conclude with a couple of quotes from Our Lord Himself:
Whoever does not honor the Son does not honor the Father who sent Him.
He that heareth you heareth me; and he that despiseth you despiseth me; and he that despiseth me despiseth him that sent me.
Heavens, what more does one need… To say of God that he is merely a “prophet” isn't being nice, it's being blasphemous, it is being insulting to God. It is a blaspheming, and therefore despising, of the Son that can only be, ipso facto, despising of the Father. You can't just say:” the Son and Holy Ghost I refuse; but I'll get the Father, thank you so much….”
Therefore, Muslims despise not only the Son and the Holy Ghost. They despise the Father, too!
