Today is Trinity Sunday. Traditionally, it’s a week when the Vicar has the day off from preaching. Instead trying to explain the Trinity is handed over to the poor curate in training. For the next three years we’ll have a curate. But in the meantime, it looks as if it’s still down to me.
I wonder what you think of when I say Trinity? Trinity may be a university college, a lighthouse or a newspaper group. It’s become a girl’s name – spiritual, a bit mysterious, kind of traditional but also modern. But for most of us, the Trinity is a bit like this: E=mc2.
We recognise it. We know it’s important. But I suspect few of us know what E=mc2 means. Or what difference it makes. And even fewer people could say why it is true. For most of us, the Trinity is similar – we know about it, we know it’s important, but what is it and why?
In essence, the Holy Trinity is the Christian belief that there is one God who exists as three persons: Father, Son and Holy Spirit. If we look at the Creed it explains that each member of the Trinity also has a role. The Father is the Creator, the Son is Jesus, the Spirit is God within us. All together, they are one God: Father Son and Holy Spirit.
How on earth can that be? Christians throughout the ages have used illustrations. You might like the clover leaf –one single leaf, with three lobes, or the Toblerone: chocolate, nut and nougat in one three sided sweet. Everyday pictures where an item is both three and one. Analogies for how God can be one in three persons. Yet they are just that: pictures from creation which give us a pattern. But how could we expect to understand God? God is so far above us, he is so majestic and awesome, we surely can’t expect to get our heads fully around him.
Christian theology tells us that we can know God because Jesus shows us what he is like. But ultimately, we cannot fully understand God. There is a difference between knowing and comprehending, experiencing and mastering. And that goes for the Trinity too. Surely, if our minds could fully grasp him then he would no longer be God!
Perhaps we need to take that on board more. Sometimes we think of God in a way which is far too cosy – my spiritual friend, or a kind of Santa up there, a father figure whose job it is to answer prayers and protect good people. God is far bigger and deeper than we imagine. It is easy in worship to try and explain everything. Often we make our God too small. Let us come to God’s presence knowing that we stand on holy ground. Trinity Sunday reminds us he is greater than we can ever imagine.
But is it a Biblical belief? Sometimes people object to the Trinity doctrine and say that it isn’t in the Bible. Certainly, if you look up the word Trinity in the index, you won’t find it. But that doesn’t mean it’s not a Biblical grounded idea.
Just look at the Gospel reading. Please turn Matthew 28. In v.19 Jesus says: ‘Go therefore and make disciples of all nations, baptising them in the name of the Father, the Son and the Holy Spirit.’ This is worth a closer look.
The Father, Son and Spirit are each mentioned, so they are separate individuals. Jesus puts them in an order of priority. But he doesn’t distinguish between them as if one is God and the others aren’t. He doesn’t say, ‘the Father, who is God, and then the Son who is something a bit lesser, and finally the Spirit too’. No, they are all on an equal footing. And he says ‘in the name of’. Not ‘names’ plural. But ‘name’ singular. Meaning one God. One God. Three persons.
The reading from 2 Corinthians 13 is similar. In verse 13 ‘The grace of the Lord Jesus Christ, the love of God and the fellowship of the Holy Spirit’. Again, all three mentioned, again seemingly put on a level with one another, again all working together. Paul gives each a different attribute and interestingly he puts Jesus first – but again it’s obvious that the belief in the Trinity is Biblically founded. It took the early church a long time to hammer out precisely what it meant – but there was never any real doubt over whether it was true.
There are many Biblical passages which support the Trinity. It’s so Biblical, that the Jehovah’s Witnesses, who don’t believe in the Trinity, actually change the words of their Bibles to make it fit their beliefs.
So if you ever hear anyone say the Trinity isn’t Biblical, you can put them right. Don’t be worried either if you can’t understand it – that’s natural. Doubt too is o.k, if we bring it honestly to God. After all, in v. 17 of the reading, the disciples doubted even while worshipping Jesus.
So the Trinity is Biblical and a mystery. But what difference does it make? What does it mean for us today and tomorrow, out of that door?
Well, it tells us that God loves this world, he’s doing something about it, and he wants us to join him. The Trinity means God exists in a kind of family, bound together in love. And that love overflows to share with the whole universe. God’s love is so generous, like a champagne fountain, overflowing from the top most glass all the way down.
I wonder if there was much champagne drunk on Thursday night? Some politicians would be celebrating, others less so. Many of us might be excused for thinking ‘Thank goodness it’s all over!’ The television crews have disappeared, the door knockers have gone home and posters are coming down. All of a sudden, we get news from the rest of the world. I expect that many people, whatever their views about the result, are breathing a big sigh of relief that it’s all over for a while.
Elections are a reminder of the importance of relationships to humanity. We belong to a society with responsibilities to one another, where our actions have effects on other people. We depend on others for our day to day existence, and they depend on us. Men and women find themselves in other people – in those intimate relationships like marriage or true friendship we find out who we really are and are given the freedom to grow. There are tradeoffs between the individual and society as a whole – a lot of political debate revolves around this. We exist in relationship with others, and, like it or not, without them we would be lost.
Christianity says the reason that we are like this is that we take after God. A God who lives in relationship. Whose very nature is Trinity. That’s another reason why the static models of the Trinity fall short. Of course the Trinity is deeper than a Jaffa cake! But it’s also much more dynamic than that. The Father, the Son, they’re words used of a family. God exists as three persons in mutual relationship. Society is the nature of God.
Think about how the Trinity shows us God in relationship: God the Father made the universe, created beings who could love one another and love him. God the Son, Jesus, came to earth. He taught people, showed us the right way to live, brought healing, and through his death forgave us our sins. God the Holy Spirit lives within us, giving us power to change, and transform our world.
In other words, God is already at work in our world, and in the gospel reading we hear that he wants us to join him. God’s on a mission, and he calls us to his side. Don’t imagine that the church takes God into the world – as if he’s strapped into a baby carrier and needs a bit of help to get out and meet people!
God’s already there. The world is his, it belongs to him. As Jesus said in v. 18 ‘All authority in heaven and on earth has been given to me’ It’s Jesus’ world. He’s already there, already at work. People may not recognise him but he’s there. ‘Go therefore and make disciples.’ Go and join what the Spirit of God is doing. Share in his work. Help people to perceive him, help them to understand and make sense of where God is in their lives. Help them to recognise Jesus.
God calls us to join him in that task. Sometimes we give it a name: Mission. The danger of giving the task a name is that mission sounds like an add-on activity for a few keen people. That’s not the case. Mission is what God does, and he commands his church to join him. Mission is intrinsic to God’s very nature. So a church cannot exist for itself and by itself. It must be outward looking.
In doing that, we have a wonderful promise, right at the end of Matthew’s gospel in V.20 ‘Remember I am with you always, to the end of the age’ Jesus is with us. Not because we’re taking him with us from inside the church. But because when we go out, we’ll meet him already in the world. Because it’s his world. Because he is already at work there, drawing people to himself. Because he is the risen and ascended Lord, before whom one day all creation will bow. Let’s therefore have confidence in his presence and our relationship with him. Amen.
