The Trinity

Address given at Templederry, St Mary's Nenagh and Killodiernan on Trinity Sunday, 11th June 2017, year A

On this Trinity Sunday we celebrate our understanding that the God we worship is one God, but three persons: Father, Son and Holy Spirit.

Jews and Muslims, our fellow monotheist ‘peoples of the book’, vehemently reject the idea of God as Trinity – they allege that Christians do not really believe in one God, but in three Gods. Even some Christians find it puzzling. How can one God possibly be divided into three persons? Surely 1 + 1 + 1 = 3?

Over the centuries Christian apologists have answered this question in different ways. We all know, I’m sure, how St Patrick illustrated the Trinity - with the trefoil-leaf of a shamrock – three leaflets within the one leaf. John Wesley said: ‘Tell me how it is that in this room there are three candles and but one light, and I will explain to you the mode of divine existence’. And it is true in mathematics that if you add three infinities the result is still infinity. But I personally don’t find such arguments helpful. The Catechism of the RC Church says that ‘God’s inmost being as Holy Trinity is a mystery that is inaccessible to reason alone’. But to call it a mystery seems like a fudge to me.

So today let me reflect on how we as Christians might seek to understand the Trinity.

We must start, I think, with how the early Christian community came to understand God.

First, the community had its roots in the Hebrew scriptures, our Old Testament. There they learned that God created all that was and is and is to come, as reflected in today’s reading from Genesis (1:1-2:4a). God had also created them in his own image. More than that, God had an intimate relationship with them, as a parent, as a father or a mother. Hence the OT stories where their God hears the cries of the people, brings them out of bondage, and in a lovely metaphor, cares for them as a hen cares for her chicks. The first Christians did not see God as remote, but as a loving and gracious God, like a parent, like a Father – and also a God for all, Jew and Gentile, male and female, slave and free. They followed Jesus’s lead by praying to their Father in heaven.

Second, the early Christian community also understood God through the life, death and resurrection of Jesus. From the apostles and first disciples they heard the story of Jesus - how in Jesus God lived and acted in new and profound ways among people. Through them they encountered the risen Christ, and heard him promise, ‘Remember, I am with you always, to the end of the age’. They learned that God was made manifest in Jesus, that God was not just out there somewhere, but had also lived as one of them, as their brother, through his Son, Jesus, who had ascended to his Father and would come again. The stories were written down in the Gospels to show that God was not only their Creator, but also Jesus Christ their Saviour and Redeemer.

Third, the Christian community came to understand God as the Holy Spirit. As promised by Jesus, the gift of the Spirit came at Pentecost. It came to the whole community in the upper room, not just to a select few. And it made them fearless. Responding to Jesus’s call, ‘Go therefore and make disciples of all nations’, they proclaimed their faith to all who would listen, baptising and gathering around them people from every nation in the Eastern Mediterranean and beyond. And the same Spirit came to the gathered groups of new Christians, just as it had to the apostles and first disciples. The Acts of the Apostles reads like an adventure story as the Spirit spreads like a wildfire through the Roman Empire. And the Epistles reveal for us how the Spirit formed the self-understanding of the gathered groups that we can now call churches.

It is clear that very early on Christians came to believe that the one God they worshipped was manifest in three different ways, as Father, Son and Holy Spirit. Today’s Gospel reading (Matthew 28:16-20) shows this when Matthew records Jesus’s command to baptise ‘in the name of the Father and of the Son and of the Holy Spirit’.

By the 4^th century the Church had captured the imperial Roman state.

Dogmatic theologians were arguing bitterly over what the Trinity really meant, amid power struggles in the church.

These disputes were eventually settled at a Council of Bishops, convened in Constantinople by the Emperor Theodosius in 381AD, which settled the doctrine of the Trinity in the words of a creed, which we now know as the Nicene Creed and still use in the Holy Communion service.

Most Christians, including Roman Catholics, Orthodox, and our own Anglican Communion maintain that this is still the best way to think about God.

It is not hard to understand the historical reasons why Christians came to believe in God as Trinity.

But I do not think that our belief that God is best understood as the Trinity should rest only on the words of scripture and the partisan arguments of Church Councils more than 1600 years ago. I believe that divine revelation did not cease when the last full stop was written in the last book of scripture – God’s creation all around us is a continuing revelation, and in the world around me I see signs of our Trinitarian God everywhere.

I see the Loving Father in the beauty of the universe he created. He has precisely tuned it to support the miraculous, evolving web of life on our planet. He has made it to be a place where you and I and all creatures can flourish and be fed - if we would only tend and care for it, and for our neighbours, as we ought.

I see the Saving Son in the widespread altruism that exists in the natural world. And I see him in communities, communities of people but also of other organisms. I see him in the worker bee’s dedication to raising a sister’s brood. I see him in the three-cornered dance of insects, fruit trees and seed dispersing animals. I see him in the cycles of death and resurrection that drive evolution. And I see him in our human capacity to love, to love each other and our neighbours as ourselves – even if we often fail to do so.

I see the Holy Spirit in the continual innovation of living creatures and ecosystems. I see him at work exploring new expressions of what is possible in the arts and the sciences. And I see him in the way that human beings, in all our variety with our different gifts, come together to build communities with meaning and purpose – including the Church, the ‘body of Christ’ as St Paul called it, among many other kinds of community.

We should not, I think, see the doctrine of the Trinity as very difficult or a great mystery. Rather we should see it as something very natural. It is very simple really – but also very profound.

Let us finish in prayer:

God of heaven and earth,

before the foundation of the universe

and the beginning of time

you are the triune God:

Author of creation,

eternal Word of salvation,

life-giving Spirit of wisdom.

Guide us to all truth by your Spirit,

that we may proclaim all that Christ has revealed

and rejoice in the glory he shares with us.

Glory and praise to you,

Father, Son and Holy Spirit,

now and for ever. Amen

The Living Church

Address given in Templederry, Nenagh and Killodiernan on Sunday 24th May 2015, Pentecost, Year B

We’re moving into Summer and Spring is almost if not quite behind us!

We all love the sense of unfolding new life and development at this time of year, don’t we? . And it is right for us to rejoice in the changing of the seasons. It is the creative power of the Spirit of God at work: as today’s Psalm 104 puts it, “When you send forth your Spirit, they are created, and you renew the face of the earth. May the glory of the Lord endure for ever; may the Lord rejoice in his works.”

This Sunday is Pentecost – what we used to call Whitsunday. For Christians it ranks alongside Christmas and Easter as one of the great festivals. It celebrates the day when the Holy Spirit filled Jesus’s followers, empowering them to begin the great task of making disciples of all nations. The first Pentecost was the spring-time of the Church, the day when the first green sprouts burst into the light of day, the day the Church was born – the birthday of the Church.

The Lectionary readings are of course all about the Spirit. Let’s have a closer look at two of them.

In the 3^rd reading, Jesus told his disciples that he would send them the Holy Spirit from the Father.

For what we know as the Holy Spirit, the 3^rd person of the Trinity, John uses the Greek word ‘Paraklētos’ in today’s Gospel (John 15:26-27, 16:4b-15), translated as ‘advocate’ or ‘helper’. On the night he was betrayed Jesus tells the disciples, ‘When the Advocate comes, whom I will send to you from the Father, the Spirit of truth who comes from the Father, he will testify on my behalf.’ He goes on to say, ‘I still have many things to say to you, but you cannot bear them now. When the Spirit of truth comes, he will guide you into all the truth’.

These are very important words, I think – Jesus tells his first disciples that they do not know the whole truth, but must trust the Spirit of truth who comes from the Father to guide them. Surely the same applies to his disciples in every age, including ours. It is too easy to say as some fundamentalists do ‘we must hold to the faith once for all delivered to the Saints’, because all truth is provisional. Jesus teaches us our faith must be open to the prompting of the Holy Spirit – it must be a living faith, open to development.

In today’s 1^st reading (Acts 2:1-21), Luke describes the events of that very first Pentecost.

7 weeks after Christ’s resurrection, 10 days after his ascension, something happened among his followers. Something that caught the attention of the crowd – citizens of Jerusalem and visitors from all over the Roman Empire, alike. Something that caused the crowd to stop and look and listen. What was it that happened?

It is this - the disciples suddenly experienced the presence of God’s Holy Spirit, in them and in their lives, just as Jesus had so recently promised them. The OT uses wind and fire as symbols of the presence of God. So it was natural for them to describe their extraordinary experience in terms of a rushing mighty wind and tongues of fire. And they were changed, changed utterly by it.

They began to speak in tongues – this is what first attracts the attention of the crowd – some people even thought they were drunk on new wine! Did they really speak in all manner of foreign languages? Or is Luke using this as a device to signify the Gospel message is universal? Or was it just the disciples’ obvious enthusiasm and joy, bubbling forth, that impressed the crowd?

Then Peter comes forward. Peter the simple fisherman from Galilee, who just seven weeks before had been afraid to admit he knew Jesus. Peter as spokesman for the others starts to speak confidently to the crowd, quoting from the prophet Joel. And Peter goes on to declare his faith in the risen Christ, with such eloquence that we are told he convinced 3000 people that day to believe and be baptised. What a change in Peter! And so Christ’s Church is born.

No doubt in principle we could explain what happened with, say, the science of psychology. But I think it’s enough to use the same words Luke did – ‘All of them - the disciples - were filled with the Holy Spirit’, and they were changed by it. And this sense of receiving and being changed by the Holy Spirit has marked out and empowered Christians in every generation ever since.

Notice this - the disciples were all together in one place when they received the Spirit.

The Spirit was a gift to the whole community who followed Jesus. I think that if Christians of different traditions were more often gathered together in one place, we would receive more of the Spirit.

I can be a Christian without going to Church, I sometimes hear people say. Well, yes – a taste for singing hymns and listening to sermons is perhaps optional. But nobody can be a Christian alone – for as Christians we are those to whom God has given his Spirit, and the Spirit is a community Spirit. We are not given it for our individual salvation; we are given it to empower us to be the Church, the community of believers, so that we may pass on the good news to others, not necessarily in words but in our lives.

I believe that the Holy Spirit has inspired people since time immemorial. Long before Jesus’s patient sowing of the seed with the disciples, the Spirit was no doubt planting seeds in the minds of the ancient prophets of Israel as they, like us, struggled to understand their relationship with God. And who can say that the Spirit has not also inspired what is good in other religions?

But for us as Christians let us rejoice in Christ’s Church as a living, developing organism, sprouting from the seed Jesus sowed, and constantly growing in new ways, guided by the Holy Spirit who Jesus sends from the Father.

So to conclude:

As we rejoice in the glorious growth and development in nature around us, let us also rejoice in the Church as a living, changing and developing organism, to use the Archbishop of Armagh’s words.

And let us pray that in this part of Christ’s Church, in the churches of our parish union, in the Church of Ireland, God’s Holy Spirit will guide us to change and develop according to God’s will:

God the Holy Spirit,

come in power and bring new life to the Church;

renew us in love and service,

and enable us to be faithful

to our Lord and Saviour Jesus Christ. Amen

(BCP p149)

An Epiphany of the Trinity

An address given at Templederry and Killodiernan on 11 Jan 2009 - the Baptism of Christ

Tracks of charged particles in a cloud chamber

Ever since I was a schoolboy, I’ve been fascinated by the pictures taken by particle physicists of the tracks of sub-atomic particles in cloud chambers.

The particles are smashed into each other in accelerators. By studying and measuring the patterns they make as they split and decay, scientists can see traces of the underlying structure of matter. The results confirm or disprove elegant theories – mathematical models - constructed by theorists.

I’m looking forward this Summer to the first results from the Large Hadron Collider experiment. Built in a circular tunnel 17 miles in circumference under the Franco-Swiss border near Geneva, it will accelerate beams of charged particles to almost the speed of light and smash them together head on. Among the things scientists hope to discover are traces of a weird particle called the Higgs boson, the last undiscovered particle predicted by the Standard Model of particle physics. Some people jokingly call it the God particle, because it gives mass to all other particles!

In much the same way, I think, as particle physicists search their cloud chambers for events that reveal the nature of matter, Christian theologians have searched the Bible for passages which reveal something of the nature of God.

The Greek word ἐπιφάνεια (epiphaneia), from which our word epiphany comes, literally means a showing forth or a manifestation. And it is during Epiphany that we are invited through the chosen readings to reflect on how God reveals himself to us, how he is shown forth, made manifest. In the Church callendar, Epiphany begins on Jan 6th, when the focus is on the story of the Magi, when the Christ-child is first shown to the gentiles. But on this and the next 3 Sundays in the season of Epiphany, until Candlemas on 2 Feb, the set readings present us with many other epiphanies, many other stories that reveal something of the nature of God.

So today I invite you to reflect on how God is revealed to us in today's readings as a Trinity - Father, Son and Holy Spirit – and what this means for us.

Psalm 29 presents us with an epiphany of God the Creator.

From time immemorial human beings have seen traces of the majesty of God the Creator in the natural world, and in the awesome power of natural forces.

Psalm 29 captures this kind of epiphany in these words:

The voice of the Lord splits the flash of lightning;
the voice of the Lord shakes the wilderness;
the Lord shakes the wilderness of Kadesh.
The voice of the Lord makes the oak trees writhe
and strips the forests bare;

I think we’ve all experienced this sense of awe when confronted by the great forces of nature, and by wild and desolate landscapes. They make us feel small and insignificant.

But this is a rather primitive idea of the nature of God, isn’t it? If this were all we knew of God, no doubt we would still be sacrificing our children to appease such a terrifying presence, as many primitive cultures have done, and as it seems the Hebrew patriarch Abraham planned to do with his son Isaac, before the angel prevented him.

Over the long centuries of OT time, the Hebrews came to see themselves as having a covenant with this powerful God, who promised to protect, strengthen and nurture them, so that Psalm 29 can finish with these words:

The Lord shall give strength to his people;
the Lord shall give his people the blessing of peace.

By the time of Jesus, Jews had begun to think of God the Creator as loving his children - the Children of Israel - as a father does. And of course Jesus built on this in his teaching. He himself clearly experienced God as like a loving Father, and he taught his disciples – and through them us - to pray to Our Father in Heaven.

God the terrible creator is transformed into God the loving Father.

The 1st reading from Acts (19:1-7) is about an epiphany of God’s Holy Spirit

The dozen or so disciples that Paul met in the great pagan city of Ephesus were followers of John the Baptist. They had been baptized into John’s baptism of repentance, but they had not been baptised or initiated as Christians. They knew nothing of the Holy Spirit, which the disciples in Jerusalem had experienced after the Ascension.

Paul explained to them that John himself had taught his disciples ‘to believe in the one who was to come after him, that is, in Jesus’. And they accepted baptism from Paul, not ‘in the name of the Father and the Son and the Holy Spirit’, the Trinitarian words we use now, but ‘in the name of the Lord Jesus’. Perhaps the earliest baptismal words were changed as later theologians began to understand the nature of God as a Trinity.

Only then, when Paul laid his hands on them, did they experience the Holy Spirit. We are told they spoke in tongues and prophesied, just as the disciples in Jerusalem had done. We are not much given in the Church of Ireland to speaking in tongues and prophesying, are we? – in fact we are rather afraid of the idea! I hate to think what the Rector and Bishop Trevor would do if I started to speak in tongues from this pulpit! But if we interpret this phrase as how the early Christians described their sense of being empowered, empowered by Jesus to do the work of God, perhaps we would do well to be more open to the idea.

The 2nd reading from the beginning of Mark’s Gospel (1:4-11) describes an epiphany in which Jesus is revealed as the Son of God at his baptism by John.


‘Jesus came from Nazareth of Galilee and was baptised by John in the Jordan’, Mark tells us. ‘And just as he was coming up out of the water, he saw the heavens torn apart, and the Spirit descending like a dove on him. And a voice came from heaven,’ – from God – ‘“You are my Son, the Beloved; with you I am well pleased”’. What an amazing vision Mark conjures up with so few words! It has inspired so many artists over the centuries to paint beautiful images.

The Baptism of Christ, by Andrea del Verrocchio, 1475, in the Uffizi, Florence

But who saw the dove, and who heard the voice from heaven? I don’t think it can have been the crowd down by Jordan’s banks, because Matthew uses the pronoun ‘he’: this vision is surely a private not a public experience. The pronoun is ambiguous. Is it Jesus who sees the vision? Possibly. Perhaps this is the very moment when Jesus the man realises his own significance as the Son of God. But perhaps more likely it is the Baptist who sees the vision. For the writer of John’s Gospel tells us that John the Baptist testified: “I saw the spirit descending from heaven like a dove, and it remained on him. I myself did not know him, but the one who sent me to baptise with water said to me, ‘He on whom you see the Spirit descend and remain is the one who baptises with the Holy Spirit.’”

Whichever it is, this passage is very important for all Christians who see the nature of God as the Trinity. This is the only place in the Gospels where we find all three persons of the Trinity – Father, Son and Holy Spirit - together at the same time. It is the defining vision of the Trinity.

The Church teaches that God is a Trinity – a Trinity of Father, Son and Holy Spirit


After analysing these and other Bible passages for a long time, around 3 centuries, Christian theologians achieved a high degree, though not complete, unanimity on this. And they expressed it in the historic creeds which we still say together.

But do we have to rely entirely on the authority of ancient scriptures and long-dead theologians to reach this understanding?


I wonder if, like the particle physicists probing the nature of matter with their cloud chambers and experiments, we can ourselves come to understand God as Trinity, by probing our own hearts and spiritual lives, and the hearts and spiritual lives of those about us? I rather think we can.

All around I see faint but unmistakeable traces of a God like a loving Father, of a Son that shows people how to relate in love to all about us, and of a Spirit that animates all creation!
