Ancient Truths in New Light

Do Christians and Muslims worship the same God?

In his book Crossing the  Threshold of Hope, published in  1994, Pope John Paul II wrote that

“In Islam all the richness of God’s  self revelation, which constitutes  the heritage of the Old and New  Testaments, has definitely been set  aside. Some of the most beautiful  names in the human language are  given to the God of the Koran,  but He is ultimately a God outside  of the world, a God who is only  Majesty, never Emmanuel, God with-us. Islam is not a religion  of redemption. There is not room  for the Cross and the Resurrection.  Jesus is mentioned, but only as a  prophet who prepares for the last  prophet, Muhammad. There is also  mention of Mary, his Virgin Mother,  but the tragedy of redemption is  completely absent. For this reason  not only the theology but also the  anthropology of Islam is very distant  from Christianity.”

Pope Benedict XVI, in that widely  reported paper delivered to scholars  at the University of Regensburg, saw  fit to quote one who based upon hard experience had a rather dim view of  the practical and concrete expressions  of the doctrine of Muhammad, namely,  the Byzantine Emperor Manuel Paleologus II, who wrote: “show me just what Muhammad brought that was new, and now you’ll find things only evil and inhuman; such as his  command to spread by the sword the  faith he preached.” The Pope then went on in his speech to contrast the Christian conception of God as  rational with the Islamic notion of  a God who is utterly transcendent,  beyond reason, inaccessible to reason,  and indeed, a God who could be  equally in accord with or opposed to  reason. God is love, God is rational,  God is Truth – all of these profound  theological doctrines of the Catholic faith are utterly incompatible with  the God conceived and described by Muhammad in his Koran.

Islam and the Trinity

The question of Islam, and how it relates to the Catholic faith, has been one much considered and spoken of in recent years. Yet there has been not much discussion or reporting of how Islam should be viewed from a Catholic point of view: for example, is it true that Catholics and Muslims worship the same God? Do Muslims  respect Jesus? Do they confess that he  is God, or merely a human prophet? What does the Koran have to say  about the doctrine of the Trinity? 

This brief article does not attempt an exhaustive study of Islam, of the  collections of sayings of the prophet, or an examination of the various schools of Islamic jurisprudence. Rather, it simply examines various doctrines set forth in the Koran, which Muslims  imagine to be the word of God dictated to Muhammad, and based on such an examination to answer the above questions for Catholics. 

Let us begin with a brief historical review of who Muhammad was, and the  religion that he preached. Muhammad came from a tribal group of originally pagan Arabs, whose practice of idolatry  was long established and well known. The religion which he invented is called Islam, which means submission to the will of God. Its adherents, those who submit to Islam, are called Muslims.

Stark simplicity

The creed of Islam is very stark  and very simple. Its primary beliefs  are summed up in the “shahada”, the  Islamic confession of faith: “there is  no god but Allah, and Muhammad is his prophet.” Muslims often imagine that this simplicity, as opposed to the complexity and mystery of the Nicene Creed and the doctrine of  the Trinity, are proofs of the truth of  their religion and of the falsehood of Christianity. The Koran, which is the  book containing Muhammad’s alleged  revelations from God through the  archangel Gabriel, is held by Muslims to be the literal word of God, dictated  from heaven.

Let us examine now what  Muhammad has to say in the Koran about what his followers are to believe. Sura 3 [67] in the Koran tells us that “Abraham was not a Jew nor yet a Christian; but he was true in Faith, and bowed his will to Allah’s (which  is Islam), and he joined not gods with Allah.” And what about Jesus and the religion which He founded?  He ascended into heaven almost 600 years before Muhammad died, but, according to the Koran, he was also a  great prophet, and – now this might  surprise you a little bit, but according to the Koran, he was also a Muslim. Sura 3 [52] tells that Jesus appeared  among the children of Israel, and “when Jesus found unbelief on their  part he said: ‘who will be my helpers to  the work of Allah? Said the Disciples:  We are Allah’s helpers: we believe in  Allah, and do thou bear witness that we are Muslims.” 

Now, it might not be ecumenically sensitive, but from a Catholic point of view, whether or not a person, or a religion, confesses the divinity of  Jesus Christ is actually very important.  If a person, or a religion, explicitly rejects the divinity of Christ, the  crucifixion, the resurrection – that is to say, if one denies the doctrine  of the Incarnation – then it follows  that any claim of compatibility with  orthodox Christianity must be rejected  as delusional or utterly duplicitous.

Divinity denied

In the Nicene Creed, Catholics confess that “I believe in … One Lord Jesus Christ, the only-begotten Son of God, born of the Father before all  ages, God of God, light of light, true  God of true God; begotten, not made; consubstantial with the Father, by  Whom all things were made.” Now  those doctrines, asserting the divinity  of Christ, are found in all approved  Creeds of the Church, and they are  regarded as basic touchstones of  orthodoxy. Let us see then what the Koran has to say about the divinity of  Christ. 

At the risk of spoiling the surprise, the Koran repeatedly and explicitly denies the divinity of Christ. In the  Koran Muslims are taught that Christ was human, that he was a prophet,  just like Moses, Abraham, and Muhammad. In Sura 4 [171] we are  told: “O people of the Book! Commit  no excesses in your religion; nor say of  Allah ought but the truth. Christ Jesus,  the son of Mary, was (no more than) a Messenger of Allah, and his Word, which He bestowed on Mary, and a spirit proceeding from Him: so believe in Allah and his Messengers. Say not  ‘Trinity’: desist: it will be better for  you, for Allah is one god: glory be to him: (far exalted is he) above having a  son.” And in the next line we are told that “Christ disdaineth not to serve  and worship Allah, nor to the angels.”

The denial of the divinity of Christ  does not stop there however. This  is a matter which Muhammad, and whoever it was that gave him his revelation, really wants to emphasise. Sura 5 notes that: “In blasphemy indeed are those who say that Allah (God) is Christ, the son of Mary.” Also, “they  do blaspheme who say: ‘God is Christ, the son of Mary.’” According to the  Koran, “Christ, the son of Mary, was no more than a messenger.” It was  pparently revealed to Muhammad  that: “…The Christians call Christ the son of God. That is a saying from their mouth; (in this) they but imitate what the Unbelievers of old used to say. Allah’s curse be upon them; how they are deluded from the truth.” [Sura 9,  30] In Sura 19 there are several denials that God would ever beget a son.

Finally, in Sura 39, we are told that  “Had Allah (that is, God) wished to  take to himself a son, he could have  chosen whom He pleased out of those  whom he doth create; but glory be to  him! (He is above such things.) He is  Allah, the one, the irresistible.” Given what we have seen of the  very clear denial that Christ is God,  that Christ is the Son of God, it should  be pretty clear that Christians and  Muslims do not “worship the same  one God.” The Koran repeatedly and  explicitly denies the divinity of Christ,  and that God could have a Son, still  less that such a Son could take is willing to pit itself against a Europe  which seems so determined to deny  its Christian roots and identity. Surely  this is an undertaking of the David  and Goliath variety. At a time when  Europe is deathly silent about some  ,500 years of formation in a Christian  context, the questions TriaLogos poses  ring out loud and clear: what is the  Christian European culture and who  is a Christian in the midst of all  the ideologies and religions storming  across the globe?

No crucifixion

That is why we should not be surprised to read that in the Koran, like some of the ancient Gnostic heretics, Muhammad denies that Christ was ever crucified. Such a fate would be unseemly for a prophet of Allah. So in Sura 4 we are told: “That they said (in boast), ‘We killed Christ Jesus, the son of Mary, the messenger of Allah’ – but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no certain knowledge, but only conjecture to follow, for of a surety they killed him not – Nay, Allah raised him up to himself.”

And there you have the Islamic repudiation of the whole Incarnation. Muhammad taught that Christ was only man, and a prophet like other prophets. He utterly denied the Trinity. With the rejection of the Incarnation goes the entire sacramental system – there is no Real Presence in the doctrine of Muhammad. No Mass, no priesthood, no sacrament of marriage (Muhammad had fourteen wives, eleven at one time; he married the youngest when she was nine years old), along with no prohibition on divorce in such polygamous relations.

In the Creed Catholics confess belief in the divinity of Christ, in His crucifixion, death and resurrection. All of these are denied by Muhammad.

Christians also confess belief in the Trinity. In the Nicene Creed we affirm our belief in “The Holy Ghost, the Lord and Giver of life. Who proceedeth from the Father and the Son, Who, together with the Father and the Son is adored and glorified.” But Muhammad says in Sura 5 that “they do blaspheme who say: God is one of three in a Trinity: for there is no God except one god.” As well as “say not ‘Trinity’: desist: it will be better for you; for Allah is one god; glory be to him; far exalted is he above having a son.”

It should by now be quite clear that those who claim that Christianity and Islam share the same faith, or that ultimately we worship and confess the same God, are manifestly in error. The Islamic denial of the Trinity, the divinity of Christ, the Incarnation, the crucifixion and resurrection, all of which are clearly set out in the Koran, must settle the matter for anyone who grasps even the most basic teaching of the Apostle’s or the Nicene Creed. We do not worship the same God. Islam and Christianity are utterly antithetical to one another. If one is true, the other must necessarily be false. If the Nicene Creed is true, then Islam is necessarily false. Keep that in mind the next time someone tells you that Islam and Christianity ultimately worship the same God, and ask them about the Trinity, the Incarnation, and the divinity of Christ, and how they reconcile the claims of the Nicene Creed with those of the Koran.
