Trinity Sunday
Isaiah 40:12-17, 27-31
Matthew 28:16-20
The first Sunday after Pentecost is always Trinity Sunday. That special day when we are meant to celebrate the Christian doctrine of the Trinity: God the Father, Jesus the Son and the Holy Spirit. Celebrating foundational Christian doctrine might not sound all that exciting, but it is!
It is always worthwhile to remind ourselves about the essence of our Christian faith after the seasons of Lent, Easter, Ascension and Pentecost. The church year now rolls along until Advent as the big festivals are complete.
The Church has marked Trinity Sunday since the mid 800’s. It was instituted to speak against the heresies of the early church as they worked out how to understand the nature of Jesus; was he only a man? Was he divine? A combination of both? How could the church understand and explain how God can be three and one.
Reference to the Trinity is woven through our services; each time I or we say ‘in the name of the Father, the Son and the Holy Spirit‘. We repeat it each week in the Creeds. The entire Christian story is retold in the Eucharistic prayer before Communion; listen for the references again this morning.
It is difficult to understand and at some point needs to be believed as part of the mystery of God. But don’t simply jump to that conclusion (or not) as tempting as it is!
The doctrine of the Trinity sets out to tell the whole truth about God, even though it is difficult. The full Christian story is that God created the world, redeemed it through Jesus and is present in the world and our lives through the Holy Spirit. All equal, all the same.
From theologian Alistair McGrath,
‘Let’s pretend that God is simply someone up in heaven, who made the world. That’s the way many Greek philosophers thought about God. It’s not a difficult idea. So why don’t Christians just adopt this simple view of God? The reason is clear. This may be an easy idea to understand, but it is a totally inadequate view of God, from a Christian point of view. Why? Because this scaled-down God is the distant and far-removed creator of this world, who never becomes directly involved in its affairs. And Christians know that God just isn’t like that. For Christians, God entered into this world in Jesus of Nazareth: “the Word became flesh and lived among us, and we have seen his glory” (John 1:14). Good theology is about telling the full story, and enabling us to see the full picture. And that means weeding out inadequate ideas about God.’
Trying to deepen our understanding of the Trinity, should help us to expand our faith ideas of what it is to be a Christian. How? The Trinity should challenge us with the truth about God. Being a Christian is not solely about turning up to church or simply being a good person. The truth of God will always be more than our minds can cope with.
The truth of God will always convict and remake us. We are created in God’s image as everyone is. We cannot remake the image to suit ourselves. It is an image we are to grow and mature into.
Secondly, the Trinity shows us that God is dynamic. God is on the move. He flows, he dances. This proves that the idea of a distant God is inadequate. We pray and worship, we believe that God is creator and lord, we know that the Spirit guides and moves us to action.
We see the action of God in Isaiah 40. The Israelites are in Babylon by force as the prophecies of the coming exile have come true. Jerusalem fell to King Nebuchadnezzar and the Babylonians in 587 BC. This section is dated from the 540’s.
Isaiah is addressing people who have suffered the trauma of exile after 40 years. There is a new generation who did not know the ‘old’ Jerusalem. The writer is bringing hope and comfort to the community whose exile is coming to an end by the grace of God. He is reminding them of God’s vastness: a God who can measure the waters in the hollow of his hand, enclose the dust of the earth in a measure, and weigh the mountains on scales. Nations are like a drop from a bucket.
The writer makes the case that God can be trusted to save the exiles. He wants to and he can. God is the source of power and will renew the strength of the exhausted and weary. Isaiah is imploring the old generation to tell the new generation about God.
Jesus’ final commandment to his disciples in Matthew’s Gospel is to ‘Go! Make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit.’ They were not to stay still in Jerusalem and never change. Thank God they did go. God is always waiting and watching over us. He wants us to move and change; to become the people He created us to be.
Now some who heard Jesus that day doubted, hesitated. Why? Maybe they were not sure of what they were seeing? Was it really Jesus? Or a vision? They were not the first people who had trouble recognising the post-resurrection Jesus.
Disciples are learners and followers; if you want to learn and follow then you are in good company. We need to make more of them. This is not about securing more members to the group but securing wholehearted commitment to Jesus, to the Trinity. We do that by following the example of Jesus and being open to the work of the Spirit in our lives. What might that look like for you?
Take comfort in the words of Jesus, ‘I am with you always, to the end of age.’ The Trinity is not something we will ever fully understand but it is an attempt to tell the full story of God. Not the absent one but the God whose love and presence can be known here and now in the ordinary every day.
God is not forgetful or careless. No one who measured the water in the hollow of his hand or weighed the mountains on a scale lacks attention to detail. Remember that God is inexhaustible. God is unending energy. Jesus is unending energy. The Holy Spirit is unending energy.
Lean into God for comfort and encouragement. Lean into Jesus and follow his example. Lean into the Holy Spirit and ask for energy and imagination. Lean into each other as we continue to learn and grow together. May we be transformed by the Trinity.
