Incomprehension is the major objection to the teaching of the Trinity. ’It doesn’t make sense,’ is what people say, and you can understand their problem. The definition of the Trinity is that there is one God who exists in three ‘persons’ or ‘personalities’: God the Father, God the Son, and God the Holy Spirit. Each member is equal in nature and substance to the others, each is fully God…yet there is one God.

How might I think about this that will help my comprehension and my faith? As we approach our subject lets be frank in laying down some fundamental Bible truths about God, his character and persons, and our “knowing” him.

1. It is important to understand that God is a mystery. This is not an excuse trotted out every time a hard question is asked about the Christian faith. Rather it is a function of God’s nature and ours; he is God and I am not and the implications of this are plain enough. Of course, there is much about God that we do know and understand because God, in His infinite grace, has chosen to reveal Himself to us. Our knowledge of him is revealed knowledge, revelation knowledge.

We don’t find him, he reveals himself to us, through His creation, through prophets, and finally through His Son (Romans 1:19-20; Hebrews 1:1-2). But however much we know, or think we know, it is well to remember that although, ‘He has also set eternity in the hearts of men; yet they cannot fathom what God has done from beginning to end’ (Eccle.3:11)

Paul, in his letter to the Romans declared,

Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgements, and his paths beyond tracing out! Who has known the mind of the Lord? Or who has been his counsellor?’ (Romans 11:33-34).

If there are things about God that we cannot understand we are in good company. If our knowledge of god is revealed knowledge, then we must allow what he has revealed to speak for itself.

2. A point sometimes raised is that the word ‘Trinity’ is not itself found in the Bible.

Neither is the word ‘Atheism’ found in the Bible but it is described where the psalmist declares ‘The fool has said in his heart, ‘There is no God’.’ (Ps.14:1)

Although ‘the disciples were first called Christians in Antioch’ (Acts 11:26) The word ‘Christianity,’ is not found in the Bible. But ‘Christianity’ defines the faith held by Christians.

Nor, indeed, is the word ‘Bible’ found in the Bible, but the ‘Bible’ is the record of God’s dealings with his people, his promises, judgements, covenants, and laws throughout…the Bible.

The presence or absence of words needn’t be significant. What matters is whether the word describes something found in the Bible, and the word ‘Trinity’ describes the nature of the godhead as it is revealed in Scripture.

3. We are not saved by theology, by having a full, exhaustive, comprehensive understanding of the Trinity. Remember, he is God and I am not. We are saved through faith in Jesus Christ, but do we have the right Jesus? This is where theology is essential.

4. That saving principle, faith in Jesus, illustrates how very important the Trinity doctrine really is because it identifies Jesus. In several places in the New Testament we see Jesus worshipped and receiving worship.

In John 20 we find Thomas falling at Jesus’ feet and calling him, ‘My Lord, and my God.’ Jesus commends him for it and goes on to say that those who haven’t seen him, yet believe as Thomas believed, are blessed indeed! (John 20:28-29) If Jesus is not fully God, if he is, as some insist, a creature, then such faith as we exercise today amounts to idolatry.

5. We are not saved in ignorance. Becoming and being a Christian is much more than an exercise in thinking and reason, but it is not less than that. Paul tells us we are to be renewed in our minds (Eph.4:23). Everything in the New Testament urges us to be intelligent about our faith. We don’t come to faith knowing so much but our walk of faith is meant to see us grow in the knowledge of God.

6. As we have already noted, God’s revelation of Himself unfolds as He reveals Himself through creation (Romans 1:19-20); through prophets, and finally through His Son (Hebrews 1: 1-2; John 14:9). To start then with the idea of the Trinity and work backwards is problematic. We can fall into the trap of reading things into Scripture instead of taking our doctrine from Scripture.

By the same token, to say that we do not understand therefore it cannot be true, is also to read back into Scripture our conclusions instead of seeing what the Bible has to say. The Bible is, among many things, an historical document and history, especially the history of ideas, can only be properly understood read forwards.

To Begin at the Beginning

The New Testament writers and Early Church Fathers did not have a complete and polished view. They “discovered” the Trinity as they thought about the undeniable witness of Jesus’ life, ministry, death, burial and resurrection, ascension, and the claims He made for Himself. They had to come to terms with what it all means. We should be thankful to them. If we start where they started and travel the same road of discovery we will likely arrive at their destination. Lets see where they started.

In the Genesis account, God declares himself superior to the sun, moon, and stars that people foolishly worshipped by showing that he created them. There are no rivals for him, as the account of Genesis shows; In the beginning God…’ (Gen.1:1)

The Old Testament witness is fundamentally monotheistic, it teaches the oneness of God. Abraham was commanded to leave the polytheistic society of his father, the land of the Chaldeans with its many gods, and follow the one true God (Gen.12:1-5)

When Moses brought down the mountain the code that the people of this one God, Israel, were to live by, that code begins with the command, I am the LORD your God…you shall have no other God before me.’ (Exodus 20:1-2)

Through the clear teaching of Isaiah God declares:

Thus says the LORD, the King of Israel and his Redeemer, the LORD of hosts: ‘I am the first and I am the last; besides me there is no god.

Who is like me? Let him proclaim it…have I not told you from of old and declared it? And you are my witnesses! Is there a God besides me?..I know not any.’’ ‘(Is.44:6-8)

In their daily prayer, Jews repeated the Shema Yisrael, the call to Israel to hear and affirm the confession of Deut.6:4, ‘Hear, O Israel: The Lord our God, the Lord is one.’

So a firm foundation of monotheism is established. It is important to understand this so that we grasp the true impact of Jesus on the society in which he ministered.

Jesus, the Clearest Revelation of God

What had those first Christians seen that could convince a stubbornly monotheistic people to believe in Jesus’ divinity?

Speak to people today about Jesus and what they will likely remember is his radical teaching and his miracles. He healed the sick, raised the dead, cast out evil spirits. And the way he taught, as well as what he taught, is striking.

There is more to the miracles than at first might be assumed, more to his claims than many realise. The Bible calls the miracles signs (John 20:30). Signs signify something, and these signs are meant to signify who Jesus really is. We are meant to realise something as we look at his life and ministry.

On more than one occasion Jesus’ first disciples got entirely the wrong idea about this. At one of those times Jesus warned the disciples of the leaven, the influence, of the Pharisees, meaning the Pharisees’ evil disposition. They thought he was upset because they had forgotten to bring bread for the journey. In exasperation, he said to his disciples:

Having eyes do you not see, and having ears do you not hear? And do you not remember?

When I broke the five loaves for the five thousand, how many baskets full of broken pieces did you take up?’ They said to him, ‘Twelve.’

‘And the seven for the four thousand, how many baskets full of broken pieces did you take up?’ And they said to him, ‘Seven.’

And he said to them, ‘Do you not yet understand?(Mk.8:18-21)

He had miraculously fed thousands. When was the last time thousands in a remote and barren place were fed by a miracle? Surely Israel in the Exodus, where God provided manna.

‘Having eyes, do you not see?’

He had power and authority to teach in a way that had never been seen before. Other teachers began with referencing other authorities, we hear it in the pulpit every Sunday, and nothing wrong with that. Jesus declared, ‘But I say to you…’ and it so impressed people they said, What is this? A new teaching – and with authority!’

‘Having ears do you not hear?’

Jesus had power and authority over sickness, whole crowds being healed at his touch (Mark 1:33-34)

He had power and authority over nature. We see this in his calming of the storm, which has much greater significance than many imagine. The sea in Jewish culture was a symbol of chaos, it was out of chaos that God brought the order of creation in the beginning, and here was Jesus bringing order out of chaos. Such was the impact on his disciples of seeing this that, Mark tells us, ‘They were terrified and asked each other, ‘Who is this? Even the wind and the waves obey him!’’ (Mark 4:35-41)

Even more remarkable, Jesus had power and authority over death. When a synagogue ruler named Jairus pleaded with Jesus for his dying daughter’s life, Jesus went to the man’s home. She is already dead, they insisted, but Jesus simply took her hand and said, ‘Little girl, I say to you, get up.’ Immediately, we are told, she got up and walked around (Mark 5:35-42)

It is as easy for Jesus to raise someone from the dead as it is for us to rouse someone from sleep!

More remarkable yet, Jesus had authority to forgive sin. When the paralytic man was lowered through the roof by his friends so he could be healed by Jesus, Jesus’ first words to him were, ‘Son, your sins are forgiven.’ Knowing the doubts of the religious leaders, their silent accusations of blasphemy, because God alone could forgive sin, Jesus said:

‘Why are you thinking these things? Which is easier: to say to the paralytic, ‘Your sins are forgiven?’ or to say, ‘Get up, take your mat and walk?’ But that you may know that the Son of Man has authority on earth to forgive sins…” He said to the paralytic, ‘I tell, you get up, take your mat and go home.’ He got up, took his mat and walked out in full view of them all.’ (Mark 2:1-12)

Do you not yet understand?’

I tell you…’ Did you notice that? Not, in the name of, or by this, that, or the other authority but, ‘I tell you…’ By what authority, in whose name, was Jesus doing all these things? ‘I tell you…’

We see it time and again, when he heals the sick; raises the dead; drives out demons; forgives sins; declares himself Lord of God’s Sabbath; when he insists that with his advent, The kingdom of God is near.’ (Mark 1:14-15) He speaks by his own authority!

But, most remarkable of all, Jesus makes the claim that he is able to command and send the Spirit of God to be with his disciples, ‘When the Counsellor comes, whom I will send to you, from the Father (there’s a Trinitarian statement right there), the Spirit of truth who goes out from the Father, he will testify about me.’ (John 15:26) The Spirit of God, in Scripture, is understood to be God in action in the lives of believers. Jesus commands the Spirit!

The Spirit of God

Who is this Counsellor? Jesus in John 14:15-17 calls him ‘Another Counsellor’ and the term here means another of the same kind. In other words, just as I have been with you so will he be in you. What will he do?

  1. He is a personal replacement for Jesus who is now in glory (another)
  2. He is so united with the Father and the Son that he mediates them to us, just as Jesus had mediated the Father (15:26)
  3. He glorifies the Son in his teaching, just as Jesus had glorified the Father (16:14)

Here is the third member of the Trinity.

Jesus is a Black Swan

Nassim Taleb wrote a book entitled The Black Swan. He tells how Europeans had only ever known white swans and so concluded that all swans are white. The sighting of a black swan in newly discovered Australia presented a dilemma.

If all swans were white then this wasn’t a swan, but if this was a swan then not all swans are white. The black swan metaphor describes a significant event that comes as a surprise that we can too easily rationalise away. The question was, are we going to review our understanding of things in light of this revelation, or are we going to stubbornly insist all swans are white, and this swan isn’t a swan at all?

In this respect, Jesus is a black swan. Will we lay aside our assumptions and order our thinking according to what the Bible has to say? You don’t explain the Trinity, You realise its revelation. That is the nature of the challenge his life and ministry presents. Remember, ‘Some responded, crying, ‘crucify!’ while others said, ‘My Lord, and my God.’

In Him Was Life

John begins his gospel with these words:

In the beginning was the Word, and the Word was with God, and the Word was God…Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men.’ (John 1:1-14)

Did you ever wonder how Jesus was able to so easily impart life? It is because, ‘In him was life…’ This cannot be said of you, or me. Our lives are contingent, they depend on God, the giver of life. Jesus’ life is not contingent, he has life in himself and can impart it where he pleases.

The writer to the Hebrews put it like this:

In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word.

After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven. So he became as much superior to the angels as the name he has inherited is superior to theirs…

When God brings his firstborn into the world, he says, ‘Let all God’s angels worship him.”(Heb.1:1-6)

Jesus is ‘the exact representation of [God’s] being…’ In other words, if you want to know what God is like, look at Jesus. Jesus is also worshipped by men and angels, and one day every knee will bow and every tongue confess that he is Lord (Philip.2:10-11) The question for us is not whether we fully comprehend the triune nature of God, but will we bend the knee now while it is still called today, while his mercy is still offered, and the choice is still ours, or will we bend the knee then when his full glory drives us to our knees, still rebellious and in our sin?

The Triunity of God

A better word for God, perhaps, is Triunity. It perhaps more closely describes what we mean when we talk about the Trinity. But long before the word ‘Trinity’ was minted, Christians knew who Jesus was. And the implications for them and us are profound, reaching into eternity.

Because of who he is we can trust him when he says our sins are forgiven, because it is God the Son pronouncing our blessed state, acceptable before the throne because of Calvary.

Because of who he is we can trust that he walks with us today through this life, because it is God the Holy Spirit that walks with us and dwells in us.

Because of who he is we can trust him with all the tomorrows God the Father graciously grants, and when there are no more tomorrows we can trust him with our death, resurrection, and eternity.

People struggle with the Trinity because we are creatures and God is Creator. We will never fully comprehend his nature. But he has revealed that he is a God of order, of community, a God of Justice, a God of love and of mercy. The clearest expression of his wonderful character is found in Jesus. The closest communion we have with him is in the companionship of his Spirit.

It is in the name of the Father, and of the Son, and of the Holy Spirit that we are baptised into that new life with our triune God (Matthew 28:19)
