    O followers of the Book! do not exceed the limits in your religion, and do not speak (lies) against Allah, but (speak) the truth; the Messiah, Isa son of Marium is only an apostle of Allah and His Word which He communicated to Marium and a spirit from Him; believe therefore in Allah and His apostles, and say not, Three (thalathatun). Desist, it is better for you; Allah is only one God; far be It from His glory that He should have a son, whatever is in the heavens and whatever is in the earth is His, and Allah is sufficient for a Protector. S. 4:171

    They indeed have disbelieved who say: Lo! Allah is the Messiah, son of Mary. Say: Who then can do aught against Allah, if He had willed to destroy the Messiah son of Mary, and his mother and everyone on earth? Allah's is the Sovereignty of the heavens and the earth and all that is between them. He createth what He will. And Allah is Able to do all things. S. 5:17

    They are unbelievers who say, ‘God is the Messiah, Mary’s son.’ For the Messiah said, ‘Children of Israel, serve God, my Lord and your Lord. Verily whoso associates with God anything, God shall prohibit him entrance to Paradise, and his refuge shall be the Fire; and wrongdoers shall have no helpers.’ They are unbelievers who say, 'God is the Third of Three (thalithu thalathatin). No god is there but One God. If they refrain not from what they say, there shall afflict those of them that disbelieve a painful chastisement. Will they not turn to God and pray His forgiveness? God is All-forgiving, All-compassionate. The Messiah, son of Mary, was only a Messenger; Messengers before him passed away; his mother was a just woman; they both ate food. Behold, how We make clear the signs to them; then behold, how they perverted are! S. 5:70-75

The above passages presuppose that when Christians say God is three they meant God, Jesus and Mary. After all, why bother mentioning that Mary ate food and that Allah could destroy her if he wanted? Doesn’t this assume that she cannot be a god or goddess if she had to eat and could be annihilated?
 

    I'm sorry but your arguments make a number of assumptions and liberal interpretations to reach your desired conclusions. First, you make the assumption that the argument the Koran is putting forward is that since Mary and Jesus eat food, neither is God. Therefore, the Koran believes Mary is part of the Trinity. However, the argument could be easily construed, since Mary and Jesus ate food, both are nothing but plain humans. This doesn't imply that Mary was part of the trinity Godhead in the Koranic view, but merely that in the Koranic view Christians viewed her as something aside from another plain human being. As is described in the article itself, some Christian sects truly worshiped her and the Church itself put her forth as Godbearer, which is more than just another human being. Indeed, Catholics continue to address prayers to her, an act that would be considered shirk in Islam (i.e., associating others with God). Hence, the Koranic argument need not be interpreted as anything more than that Jesus and Mary are both human beings.

The next passage should help erase any doubts that this is what the Quran means by all this:

    And when God said, ‘O Jesus son of Mary, didst thou say unto men, "Take me and my mother as gods, apart from God"?’ He said, ‘To Thee be glory! It is not mine to say what I have no right to. If I indeed said it, Thou knowest it, knowing what is within my soul, and I know not what is within Thy soul; Thou knowest the things unseen I only said to them what Thou didst command me: "Serve God, my Lord and your Lord." And I was a witness over them, while I remained among them; but when Thou didst take me to Thyself, Thou wast Thyself the watcher over them; Thou Thyself art witness of everything.’ S. 5:116-117
 

what Christians truly believe becomes apparent to anyone familiar with the basics of the Christian faith. In the first place, orthodox Christians have never taken Mary as a goddess alongside God. If the Quran were referring to a heretical group of Christians known as the Maryamites this would then serve to strengthen the position that these verses do not address Trinitarians, but apostates that deviated from the true faith.

Roman Catholic Mary Worship by the evangelical minister John MacArthur Jr.  ]The Roman Catholic view of Mary is pagan, it is utterly pagan.[/size]

To this day the worship of Mary is one of the principal points of separation between the Graeco-Roman Catholicism and Evangelical Protestantism.
the veneration of Mary gradually degenerated into the worship of Mary; and this took so deep hold upon the popular religious life in the Middle Age, that, in spite of all scholastic distinctions between latria, and dulia, and hyrerdulia, Mariolatry practically prevailed over the worship of Christ.
..The popular religious want had accustomed itself even to female deities, and very naturally betook itself first of all to Mary, the highly favored and blessed mother of the divine-human Redeemer, as the worthiest object of adoration.
The Festivals of Mary.
This mythical and fantastic, and, we must add, almost pagan and idolatrous Mariology impressed itself on the public cultus in a series of festivals, celebrating the most important facts and fictions of the life of the Virgin, and in some degree running parallel with the festivals of the birth, resurrection, and ascension of Christ.

Does the Roman Catholic Church promote idolatry? According to the scripture and its own practices, yes it does. "Therefore, my beloved, flee from idolatry," (1 Cor. 10:14).

Watchmen Bible Study Group]It has been said that actions speak louder than words. And while the average Catholic may tell you that they do not worship the Mother Mary, their actions say something quite different. [/size].

we have already indicated that the historic Christian teaching has never been that God is three or the third of three, which would be tritheism (three separate gods forming a unity) as opposed to Trinity (Tri-unity), ONE God who exists in Three distinct yet inseparable Persons (the Father, the Son, and the Holy Spirit). Third, orthodox Christians have never taught as part of their doctrine that Jesus is the third Person of the Trinity. Rather, he is the Second Person

Fourth, Muslims believe that Allah of the Quran is the same as God the Father of the Holy Bible
