In the last blog post on this subject we noticed that many Muslims do not understand the Christian doctrine of the Trinity. This is because their book, the Qur’an either deliberately or ignorantly misrepresents the doctrine. We call this a “straw man” argument—a “straw man fallacy” occurs when a person creates a misrepresentation of his opponent’s position and attacks it instead of the true position of the opponent. Christians must not be guilty of such fallacies. The Ninth Commandment of God’s Law forbids “falsify[ing] any man’s words” (Heidelberg Catechism, LD 43).
When the Qur’an presents Christians as worshipping Jesus and His mother “in derogation of Allah” (Surah 5:116) or presents Christians as joining “other gods with Allah” (Surah 5:72-73), the Muslim’s supposedly inspired text grossly misrepresents what Christians believe. The Trinity does not consist of Allah, Jesus and Mary, and the Trinity does not consist of many gods. Consider another text from the Qur’an: “They do blaspheme who say: Allah is one of three in a Trinity: for there is no god except one God” (Surah 5:73).
Two concepts in Islamic theology make it very difficult for the Muslim to understand the Christian doctrine of the Trinity—in addition, of course, to the natural depravity of the human heart. Those two concepts are tawhid and shirk.
Tawhid is the absolute oneness of Allah—Islam is a religion of absolute, non-negotiable, Unitarian monotheism. Muslims view other religions (except Judaism) as polytheistic. Hinduism, for example, is polytheistic, for Hindus do indeed worship many gods. Christianity, however, is not polytheistic, for Christians worship only one God. However, when Muslims hear that Christians worship Father, Son and Holy Spirit (or when they imagine that Christians worship Allah, Jesus and Mary!), they conclude wrongly that Christians are polytheistic.
Shirk is the unforgivable sin (in Islam) of associating others with Allah. Muslims fear the sin of shirk above all other transgressions. Allah can forgive adultery, murder and every other sin, but Allah will not under any circumstances forgive one who has died in the sin of shirk: “Allah forgiveth not that partners should be set up with Him, but He forgiveth anything else to whom he pleaseth; to set up partners with Allah is to devise a sin most heinous indeed” (Surah 4:48). “Whoever joins other gods with Allah—Allah will forbid him the Garden, and the fire will be his abode. There will for the wrongdoers be no one to help” (Surah 5:72).
No wonder that the Muslim is especially prejudiced against Christianity—it has been ingrained into him that Christianity is shirk! What the Christian needs to do, therefore, in witnessing is to demonstrate to the Muslim neighbor that the doctrine of the Trinity has nothing to do with shirk. And the Christian must pray that the Spirit of God might open the heart of the Muslim neighbor to receive the truth. Ultimately, we can only present the truth. We cannot convince anyone of the truth. That is the work of God’s Spirit, who blows where He wills in the hearts of God’s elect (John 3:8).
The word Trinity is not found in the Bible, but that should not disturb us, for every field of knowledge has technical vocabulary and terminology. The word Trinity is shorthand for theological concepts that are found in the Bible. The word Trinity explains who God is—in a certain sense, He is one; and in another sense, He is three. He is one God in three distinct persons. This is basic Christianity, but the Muslim will find it confusing.
The Bible teaches that there is only one God. This is the teaching of the Old Testament. When the Gentiles worshipped many gods, Israel confessed and worshipped only one God. “Before me there was no God formed, neither shall there be after me. I, even I, am the LORD, and beside me there is no Saviour” (Isaiah 43:10-11). This is also the teaching of the New Testament—Christians did not jettison their monotheism even when they confessed that Jesus Christ is Lord. They continued to confess and worship only one God, the same God as the God of the Old Testament. The Greeks and Romans worshipped many gods, but the church steadfastly remained monotheistic. “There is one God and one Mediator between God and men, the man Christ Jesus” (I Timothy 2:5).
Nevertheless, the Bible does not hesitate to give the name of God, ascribe the attributes of God, attribute the works of God, and present the worship of God to three individuals—to the Father, to the Son and to the Holy Spirit.
The Bible gives the name of God to the Father, to the Son and to the Holy Spirit. The Bible ascribes the attributes of God to the Father, to the Son and to the Holy Spirit. The Bible attributes the works of God to the Father, to the Son and to the Holy Spirit. And the Bible presents the worship of God to the Father, to the Son and to the Holy Spirit.
Many texts could be cited to prove the points above, but I forbear for lack of space. The point, however, is this—the Father is called God, the Son is called God, and the Holy Spirit is called God, and yet there is only one God. (Notice, by the way, contrary to the misrepresentation of the Qur’an, that it is not that Allah is called God, Jesus is called God and Mary is called God. Nor is that the Son is called God and joined as a secondary God to Allah. Nor is that others are worshipped as gods alongside Allah. The doctrine of the Trinity means that the Father, Son and Holy Spirit are equally God).
To explain the truth of the Trinity, the early church needed to use terminology. In what sense is God one, and in what sense is God three? The theological terms on which the church settled were being or essence, and person. Of course, the early church used Greek terms (ousia and hypostasis). These terms became all the more important because of the presence of false teachers in the church. For example, a heretic called Arius (d. 336) agreed to call the Son of God homoiousion, which means of a similar essence or being to the Father, but he baulked at the word homoousion, which means of the same essence or being as the Father. (The astute reader will notice that the difference between those two words, and therefore the difference between heresy and orthodoxy, is one letter—the smallest Greek letter, iota!). These theological debates occurred long before Mohammed’s birth, as I explained in the last blog post on this subject.
The being or essence of something makes it what it is, and distinguishes it from every other being. Everything apart from God is creature. The divine being of God is unique—and one. There are not two, or three beings called God. There is one God, one divine being, or one indivisible Godhead.
A person is a conscious, intelligent, active individual distinct from other persons. The writer of this blog post is a person. The individual reader is another, distinct person. This world has billions of human persons in it.
The difficulty is this—in our human experience, one human being is also one human person. No analogy or illustration exists in which one being is more than one person. Yet that is who God is—He is three distinct persons subsisting in one divine being. To understand something of that, or to grasp that, is to understand the doctrine of the Trinity. The Father is not the same person as the Son or the Holy Spirit, yet He shares the same being as the Son and the Holy Spirit. The Son is not the same person as the Father or the Holy Spirit, yet He shares the same being as the Father and the Holy Spirit. The Holy Spirit is not the same person as the Father or the Son, yet He shares the same being as the Father and the Son.
Is that deep and mysterious? Absolutely! Is that illogical, contradictory and impossible to reconcile with human reason? Absolutely not!
There are two more significant truths about the Trinity that we must bear in mind.
First, the relationship between the three persons of the Trinity is one of equality. Christians do not worship one person “in derogation” of the other persons. Christians view the Father, Son and Holy Spirit as coequal in power, glory and majesty—there is no gradation of being or difference of rank. The Father is not more divine than the Son or the Holy Spirit, for example. The Father is not higher, and the Son is not subordinate to the Father in the being of God. Remember the word homoousion—of the same essence. There is also no time in the Trinity—the Trinity is eternal, which means that the Father, the Son and the Holy Spirit are co-eternal. The Father is not before the Son or before the Spirit.
Second, the relationship between the persons of the Trinity is one of perfect love and fellowship. The Father, the Son and the Holy Spirit are not rivals, but holy family. The Father loves the Son in the Holy Spirit, and the Son loves the Father in the Holy Spirit. God, therefore, is not a lonely deity, but He is the living God, full of life, love and fellowship, within Himself, within His own being. It is because of this love of God within the being of God that God is capable of loving the creature.
This God—the Father, the Son and the Holy Spirit—is the God of our salvation.
Next time, DV, we will explain what we mean by the Christian confession that Jesus is the Son of God, something about which Muslims have many misconceptions.
