Introduction:
The world religion of Islam was founded by an Arabian visionary named Ubu'l Kassim, who was born in the city of Mecca in A.D. 570, and who would later be named Muhammad, which means, "one highly praised.". Muhammad claimed that he received divine revelation from God through the angel Gabriel. These revelations are considered to be the very foundation for the writings of the Qur'an. Muslims affirm that these writings were given orally by Muhammad to others who wrote them down piece by piece over a period of twenty-three years and later compiled them into what is now considered the Muslim Holy Book. The Qur'an is divided into 114 chapters called suras, and is considered to be an expression of the divine will of God among men. As Muslim theologian, Muhammad Khan explains, "The Qur'an, is the record of the verbal revelation vouchsafed by God to Muhammad, the prophet of Islam, over a period of twenty-two years (610-632). It is the very words that God put in the mouth of the prophet (Deut. 18:18). It contains all truth (John 16:13) for the guidance of mankind. Its message is universal. It affirms the truth of all previous revelations and the righteousness of all Prophets." Given these claims, it is essential to examine the teachings of the Qur'an to determine if they are compatible with the theology of the Old and New Testament. On the surface, there are some similarities between Islam and Christianity. They are both monotheistic, have a belief in spirits and angels, a future impending judgement, heaven and hell, and a future resurrection. In addition, both religions were established by historical verifiable figures and believe that God has revealed Himself through the prophets by divine revelation. However, there are many key differences in the foundational tenants of each religion, such as the character and attributes of God, the person of Jesus Christ, and the way of salvation. It is my purpose in this essay to narrow the focus to the Islamic doctrine of Christ and to examine its teachings in light of Scripture. It is my belief that the foundational doctrines in the Qur'an regarding Christ are incompatible with Biblical Christianity, and I will attempt to demonstrate that the Islamic worldview is faulty and often inconsistent even within its own claims
The Person of Christ:
To better understand the Islamic doctrine of the person of Christ, it is vital to comprehend that the most prominent characteristic of God in the Muslim mind is the notion of pure monotheism. This foundational Muslim belief can be summed up in the Islamic confession (shahada): La ilaha illa Allah, Muhammad rasul Allah, "There is no God but Allah and Muhammad is Allah's Apostle." Islam teaches that the Muslim deity, "Allah", is the one true God and that all other views of God are false. As Muslim apologist Muhammad Khan writes, "The Qur'an is insistent upon the unity of God and emphatically condemns any doctrine, idea, or concept which might directly or indirectly tend to associate any other thing or being with God as a partner or equal." As the Qur'an so clearly states, "Say: He is God alone: God the eternal! He begetteth not, and He is not begotten; and there is none like unto Him." (Sura 112:2-5). It is evident that the Qur'an not only denies the concept of the Trinity, or a plurality within the oneness of God, but it also emphatically states that Christians are unbelievers or infidels because of their Trinitarian beliefs. "They surely are infidels who say, 'God is the third of three.' For there is no God but one God: and if they refrain not from what they say, a grievous chastisement shall light on such of them as are infidels" (Sura 5:76). The greatest of all sins in the Islamic faith is the sin of "shirk", or the assigning of partners to God. As the Qur'an clearly states, "God truly will not forgive the joining other gods with Himself. Other sins He will forgive to whom He will: but he, who joineth gods with God, hath erred with far-gone error." (Sura 4:116).
It is apparent that Muhammad did not have a correct understanding of what Scripture teaches regarding the doctrine of the Trinity. Christians are not polytheists who believe in three gods, but rather are monotheists who believe that God is only one God who is a triune Being. The trinity is the belief that God is one in nature and yet He is three in persons. God is one in essence or Being and within the unity of the one God there are three Persons; the Father, the Son, and the Holy Spirit. All three persons share the same nature and attributes. As apologist Norman Geisler explains, "By saying God has one essence and three persons it is meant that he has one 'What' and three 'Whos.' The three Whos (persons) each share the same What (essence). God is a unity of essence with a plurality of persons. Each person is different, yet they share a common nature." In addition, a verse in the Qur'an implies that Muhammad may have also misunderstood the composition of the personhood that makes up the Trinity. According to Sura 5:116, the Christian view of the Trinity consists of God the Father, Jesus the Son, and Mary the Mother. "And when God shall say- O' Jesus, Son of Mary: hast thou said unto mankind-'Take me and my mother as two Gods, beside God?' He shall say- 'Glory be unto Thee! it is not for me to say that which I know to be not the truth…'".
