Is the Trinity a Contradiction?

In my recent series on the essential beliefs of Christianity, I received a comment from a reader who claimed that I hadn't offered a cogent argument for the Trinity. This isn't the first time I've heard the claim that the Trinity is a contradictory concept. The doctrine of the Trinity has been challenged by everyone from Jehovah's Witnesses to Muslims as contradictory.

What is a Contradiction?

A contradiction occurs when someone asserts a claim resulting in the conclusion that A does not equal A at the same time and in the same way. To briefly understand what I mean, take this well-worn example of a syllogism:

      1. All men are mortal

      2. Socrates is a man

These two premises are not really controversial. But we can know something else about Socrates by looking at them:

      Conclusion: Socrates is mortal.

This conclusion follows necessarily from the premises. There is no escaping it. Socrates is part of the set "all men" and if everyone in the set of all men are mortal, Socrates must be mortal, too.

But what if I make an additional claim about Socrates, such as:

      3. Socrates is immortal

If I assert premises #1, #2, and #3, I would have a contradiction. Socrates cannot be both mortal (from #1 and #2) and immortal (from #3) at the same time and in the same manner. Premise #3 could of course not be talking about the physical body of Socrates but referring to his work. In such a case, statement #3 holds no bearing on the other two statements, since they are completely different concepts. But if statement #3 means immortal in the same sense that statement #1 does, then Socrates cannot be a man and immortal because it would mean that Socrates is mortal and while he is at the same time the opposite of mortal. Both cannot possibly be true.

The Argument Against Contradiction

Since we know now what it takes to call an idea contradictory, we can use this understanding to see if the Trinity fits the definition of a contradiction.

      1. If the doctrine of the Trinity defines God as being both one and more than one at the same time and in the same manner then it is contradictory and therefore false.

Next, we declare that God is monotheistic. This is a staple of Christian belief:

      2. There is one God.

But Christianity teaches of a plurality within God. Supported by scripture, it makes the claim that the Father, the Son, and the Holy Spirit can express themselves differently. The Son may pray to the Father or submit to His will. The Father may send the Spirit, and so on. But they are each called God. So, we get another premise:

      3. The person of the Father is God, the person of the Son is God, and ;the person of Holy Spirit is God.

      4. Therefore, God is one being comprised of the persons of Father, Son, and the Holy Spirit (from 2,3).

If we are to now claim that the Father is a being, the Son is a being, and the Holy Spirit is a being, we would have a contradiction. You would have God is three beings and God is one being. Certainly both cannot be true. However, that is not the Christian doctrine. The Christian doctrine is that God is one being comprised of three persons. In my last post I showed how personhood is separate from being. We can create a sub argument here from the facts of that post:

               5a. Personhood is not the same as being if the number of persons of an entity differs from the number of beings present in itself.

               5b. A plant is an entity whose number of persons (zero) differs from the number of beings (one) present in itself.

               5c. Therefore, personhood is not the same as being.

So, because we've clarified the concept of personhood and being, we can add an additional proposition to our argument:  

      6. Therefore, God can be one being comprised of a different number of persons without contradiction (from 4,5c).

      7. Therefore the doctrine of the Trinity is not contradictory ( from 1,6)

By arguing thusly, one can see that the doctrine of the Trinity is not contradictory. One must add additional premises to the argument, and those premises must properly reflect Christian doctrine.

A Christian Must Believe in the Trinity

In this recent series, I've been working through some of the essential beliefs that identify someone as a Christian. Previous posts have discussed Christianity as a monotheistic faith. We believe there is only one God who has ever existed throughout all of reality. But monotheism isn't exclusive to Christianity. Most people will recognize that Judaism and Islam are also monotheistic.  Christians hold to a very unique type of monotheism. We've also talked about how Christianity holds to the divinity of Jesus, but that Jesus is not the same being as God the Father. In order to be considered a Christian, one must believe that Jesus is God the Son.

At first glance, it seems that the two statements are contradictory. There is only one God, yet there is God the Father and God the Son and one is not the other. To explain exactly how this works, though, has tongue-tied many people throughout the centuries. Add to this another complication as Christians also believe the Holy Spirit is God, and yet He is distinct from the Father and from the Son. How can such a seemingly illogical position be true? The answer lies in the concept of the Trinity,

The Trinity – What is it?

To describe the Christian belief of the Trinity is actually quite simple, but it takes a bit of careful thinking to make sure the concept is properly understood. To say God is a Trinity is to say that God is one being comprised of three persons. The term "Trinity" was first used for the three persons comprising God by the early Church father Tertullian around AD 200.1 Tertullian saw a distinction between what it means to be a person and what it means to be a being. Our difficulty today is primarily because most people think the terms are synonymous. We see a person and we say that the person is a human being. One person = one being.

However, it isn't always the case that the attributes of a being are the same as the attributes of a person. To prove my case, let's proceed downward rather than upward. When Tertullian talks about a being, he means that there is one substance that makes up the entity of God. When we look at our own bodies, we see that every part that properly belongs to our body should be considered human. Every cell is a human cell. We are made up of human "stuff" if you will. Similarly, every part that makes up a plant is "plant stuff." A plant is also a being; it is a living thing that exists. But no one would claim that a plant is a person. That would be foolish!

So, we have two cases here. We recognize a plant as a being, but it has no personhood within it. It has a personhood count of zero, if you will. We also recognize a human as a being that has a personhood count of one. This means that personhood is different from being, as a being can exist without personhood. It then follows that it isn't contradictory to say that God is a being with a personhood count of three. It may be the case that we see no parallel here on earth, it may be the case that there is no other being in all of reality that can claim multiple personhood. However, it is clear that the claim of one being in three persons is not a contradiction, any more than claiming a plant is a being with no personhood should be considered such.

The Trinity – Its Necessity

The Bible clearly recognizes God the Father as God. That claim is usually not disputed. However, as I mentioned last time, it also recognizes Jesus as God and it identifies the Holy Spirit as God, too (Matt. 28:19, Acts 5:3,5, Isa 63:10, 1 Cor. 2:10-11). These three persons are each recognized as fully God and yet God is one. If one denies the triune nature of God, then one is forced into denying some portion of scripture.

Beyond the reconciliation of Scripture, the doctrine of the Trinity holds additional advantages. I've argued this before, but it is through the relationship within the Trinity that God can be considered completely without need. Only a being like the Trinity can be all-loving, and only within a trinity can God express His own humility.

Of course, no one can say exactly how all the aspects of the three-in-one work. That shouldn't be a surprise, though. Scientists today have really good data on quantum models of matter, but you don't have to be able to explain all aspect of quantum mechanics to believe it's true. When talking about God, one is referring to a being that transcends humanity; therefore one should expect that there would be aspects to His nature beyond our comprehension. But that doesn't mean that we cannot apprehend the basic understanding of the Trinity. God is three persons who comprise one being and each is fully God.

A Christian Must Believe That Jesus is God

I've begun a series of blog posts talking about the necessary beliefs one must hold to be considered a Christian. As a guide, I've been looking at the Nicean Creed to formulate the basic beliefs that define the Christian faith. One clear aspect of the Christian faith is the Lordship of Jesus Christ.
Right on the heels of declaring monotheism, the church fathers also declare that Jesus is God:

We believe in one Lord, Jesus Christ,
the only Son of God,
eternally begotten of the Father,
God from God, Light from Light,
true God from true God,
begotten, not made,
of one Being with the Father.
Through him all things were made.

Jesus is equal with the Father

Notice that the emphasis on this part of the creed is to place the Son on equal footing with the Father. That's why the repetition of "God from God, Light from Light, true God from true God" is used. In the early days of Christianity there were several heresies that cropped up trying to claim that Jesus is in some way lesser than God the Father. The Arians, like the modern day Jehovah's Witnesses, held that Jesus was God's first creation. Jesus is a "mighty god" but not "Almighty God."

Christians had long held that Jesus is God as much as the Father is God. He claimed the honors afforded to God and the attributes ascribed to God. He forgave sins only God would and received worship that is reserved for God alone.1 Robert Wilken writes that the Greek philosopher Celsus was offended by the Christian view of God even in the second century. In discussing his views, Wilken says Celsus is fine with those who would hold Jesus in some type of divine status, such as that reserved for the Caesars. Celsus wasn't convinced that Jesus even deserved this level of honor, but as long as those worshippers recognize the "high God" as greater than lesser deities, it would be OK. Wilken then writes, "The Christians, however, made even more extravagant claims: they said that Jesus was unique among the gods and that he should be worshipped to the exclusion of all other gods. To Celsus such excessive adoration set up Jesus as a rival to God and undercut the worship of the one God." 2

Jesus is different from the Father

While Christians recognize Jesus as being fully God, equal with the Father, they recognize that Jesus is not the same person as the Father. He is not the Father, but the Son. In scripture, we see Jesus coming from the Father (Jn. 5:37, 12:49), He prays to the Father (Mt. 26:39, Lk 23:34,Jn 17:1), He obeys the Father (Lk 22:42, Jn 6:38), and He humbles Himself before the Father (Phil 2:4-8). Jesus is distinct from the Father but both He and the Father are recognized as God.

The Arian view of Jesus was the motivating issue that caused the church fathers to gather from across the globe and convene the first church council in Nicea. The formulation of the Nicean Creed was the result. Its purpose was to clearly establish the equality of Jesus with God the Father while still maintaining the concept of a single God. The church fathers did this by distinguishing between the concept of personhood and being. Next time, I'll unpack the teaching of the Trinity a bit more. For now, recognize that one must believe that Jesus is God in order to be a Christian.

A Christian Must Believe There is One God

Yesterday, I began a series talking about what beliefs someone must hold to be considered a Christian. While there are many different Christian denominations that exist, there are certain beliefs that are essential which all Christian denominations hold. These core beliefs identify Christianity from all other faiths and I had said there that the Nicean Creed is a really good starting point for identifying just what are those essential beliefs.

The first section of the creed sets affirms a core concept of God that stems from the Jewish Old Testament. It reads:

We believe in one God,
the Father, the Almighty,
maker of heaven and earth,
of all that is, seen and unseen.

Right off the bat, Christianity is identified as a monotheistic faith. One God and no others. This is key to all subsequent understanding of God, especially when considering His attributes.

For God to be Almighty, there can only be one

God is first identified as "Almighty." Most people understand the word God to mean a being that is all powerful. But that also means that God must be a single being. For if God is almighty, then He can have no equal. As a contrast, some later versions of Zoroastianism held to a concept of two beings, one good and one evil, who were equally powerful and locked in a constant state of war.1 But you cannot claim that a god is all-powerful if that god cannot win a fight with his enemy! The fact that the war exists at all shows that the god has limited power; his power cannot govern his foe. The problem would of course get worse with multiple gods, limiting the power of one's god even more as the other gods multiplied.

So, in order for God to be Almighty God, He has to be a single being. This is a straightforward logical understanding of God. Christians believe in one Almighty God (Deut 6:4, john 17:3, 1 Tim 2:5). That means that faiths such as Mormonism are excluded from Christianity immediately. Mormonism holds that many beings can become just as God the Father is now2, making God something less than what the creed establishes.

Mormons also believe that God has progressed through time to become God.3 He wasn't always almighty but he is now. Such a statement is self-contradictory since there is some mechanism (the eternal progression law or function or whatever) that God cannot have dominion over. Instead, He must obey its precepts to become God himself. That again means that the God of Mormonism isn't Almighty.

All of reality depends on the One God

The next part of that first sentence declares that God is the maker of heaven and earth, whether those things are part of the natural world (seen) or the spiritual world (unseen). All of creation relies upon God for its existence. God didn't need to create the universe, but He chose to do so. This makes God completely without dependence and when He creates, He creates out of nothing (Gen. 1:3-29, Heb. 11:3, Acts 14:24-25, Rev. 4:11). But in the Mormon view of God, the universe is eternal and God simply reshapes and refines pre-existing materials.4 If this is so, then we again see that the god Mormonism affirms is not the God of Christianity. Therefore, we can quickly declare that Mormons fall outside the definition of Christian by their denial of these essential attributes of God.

What Disqualifies Someone from Being a Christian?

Christianity is an evangelical faith. What I mean by that is that ever since its founding, Christians have tried to spread their faith through efforts at evangelism and conversion. From Jesus' command in Matthew 28:19 to "Go therefore and make disciples of all nations" to Paul's various missionary journeys to the proselytizing of all nations through the church's history, Christians have been called to share that "there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved" (Acts 4:12).

In past centuries, it was pretty easy to identify which people were Christians and which weren't. However, as sects such as the Jehovah's Witnesses and the Mormons have appeared, differentiation has become more difficult. Recently, I was able to observe my friend Brett Kunkle pretend to be a Mormon elder in front of a group of nearly 800 Christians. In his Mormon persona, he said that many Christians would come up to him and other LDS and claim that they are not Christian. "So," he challenged, "can anyone provide me with a definition of a Christian?"

Several people in the audience tried. One said that it was trusting in Jesus for one's salvation. But the Mormon would say that he does trust in Jesus for his salvation. Another said it was believing in the God of the Bible. Kunkle again countered that Mormons do believe in the God of the Bible. The Bible is one of their four standard works. A few more tried to define God as being three in one, and Brett returned the volley by saying that the LDS church affirms that God is three in one, but it turns on what you mean by saying that God is three in one. Unfortunately, no one was equipped to provide a good definition of the Trinity nor did anyone spot Brett's LDS misrepresentation of the Trinity.

To me, this is tragic. Every Christian should know at least a basic working definition of what Christianity is. Imagine a biologist who has devoted his life to studying dogs. He has spent years in school earning a degree in veterinary medicine and biochemistry. He has years of research behind him, reading books and documentation on dogs and their inner workings. Dogs have been his life! Would you expect a person to be able to tell you how to identify an animal as a dog? Of course you would! And you wouldn't expect his to reply with a general description such as "a pet with four legs and a tail." That definition fails because it can apply to a mouse or a cat. In order for the definition of a dog to be functional, it would need to talk about things that are unique to dogs alone. They would need to be specific attributes, such as their sensitivity for scent, their specific shape, their teeth, and so on.

Similarly, Christians should be able to provide a working definition of what it means to be a Christian. It needs to be specific with identifiable attributes. In fact, the early Christian church was very concerned with this, as different groups kept appearing that claimed to be Christian. The early Church realized that the point of their uniqueness rests in two places: 1) in the proper understanding of God as one being comprised of three persons, including Jesus as the second person of the Trinity and 2) a trust in the work of Jesus alone in saving us from our sins.

The definition of Christianity became so important that the church even formulated a way to affirm that one holds to the foundational aspects of the faith. First shaped in 325 at the Council of Nicea, we know it today as the Nicean Creed. It basically reads:

We believe in one God,
the Father, the Almighty,
maker of heaven and earth,
of all that is, seen and unseen.

We believe in one Lord, Jesus Christ,
the only Son of God,
eternally begotten of the Father,
God from God, Light from Light,
true God from true God,
begotten, not made,
of one Being with the Father.
Through him all things were made.
For us men and for our salvation
he came down from heaven:
by the power of the Holy Spirit
he became incarnate from the Virgin Mary,
and was made man.
For our sake he was crucified under Pontius Pilate;
he suffered death and was buried.
On the third day he rose again
in accordance with the Scriptures;
he ascended into heaven
and is seated at the right hand of the Father.
He will come again in glory to judge the living and the dead,
and his kingdom will have no end.

We believe in the Holy Spirit, the Lord, the giver of life,
who proceeds from the Father and the Son.
With the Father and the Son he is worshiped and glorified.
He has spoken through the Prophets.
We believe in one holy catholic and apostolic Church.
We acknowledge one baptism for the forgiveness of sins.
We look for the resurrection of the dead,
and the life of the world to come. Amen.1

While there is some debate between Eastern Orthodox churches and those in the West as to whether the Spirit proceeds from the Father alone or the Father and the Son, the Creed serves as a really good definition of the necessary beliefs one must hold to be considered a Christian. Jehovah's Witnesses and Mormons would deny that Jesus is "one in being with the Father" and that means they cannot be defined as Christians as we use the word.

I'll look more specifically at the details of the Creed in upcoming posts, but I hope that you will at least take away the idea that there is a good working definition of what Christianity looks like. It is a set of believes about God, Jesus, and the one true faith that forgives sins. Anything else is simply a counterfeit.
