Today is Trinity Sunday, when the Church remembers that God is “one God, Father, Son, and Holy Spirit”. Three in one, one in three. If that has always confused and perplexed you, then welcome to the club! It’s no coincidence that many priests make sure their curate is on the rota to preach on this particular Sunday! But just because it is a complex doctrine, it is far from an outdated or pointless belief. In fact, as much as any other Christian belief, the Trinity gets to the heart of what God is all about and what he expects of us. There are, after all, two important things we can say about the Trinity.
Firstly, the Trinity is a mystery. However much thought goes into it, however much we study, we’ll never fully understand the Trinity. I used to ask my students to think of analogies of what “three in one” could mean – some would follow St Patrick in suggesting shamrocks (three leaves in one sprig), others would suggest water, one element that can be three forms: liquid, steam or ice. And I even remember one group being particularly inventive by suggesting the theology of a creme egg – one sweet in three parts: the chocolate, the sickly sweet white part, and the smooth yellow centre. All this, of course, is not particularly helpful to understanding what is essentially a great mystery about God. And perhaps understanding this mystery is less important than asking why our faith teaches this mystery – what does it mean to us that God is three in one?
Well, that is where we come to second point and this turns everything else about the doctrine upside down. The philosopher Martin Buber wrote: “In the beginning was relationship”. And that little word is at the heart of what the Trinity means – “relationship”. The early church theologians described the Trinity as a dynamic dance of love between the Father, Son, and Holy Spirit. After all, love can’t exist in isolation, it can’t exist by itself. So, yes, the Trinity is a mystery. It is, though, a mystery that discloses something very simple about God. It reveals that God, in the very depths of his being, is relationship; God is love.
This has huge implications in our world of suffering, illness, grief, oppression, prejudice, violence, and inequality. It is when we step out of our isolated, selfish selves, it is when we enter into caring, peaceful, and compassionate relationships with each other, with nature, with our environment, that God is revealed to the world. The Christian philosopher Gabriel Marcel talks about “absolute availability”. Because God is relationship, love is not an optional extra for Christians and that has, in our local and global world, far-reaching expectations of each of us. The doctrine of the Trinity demands that availability, responsibility, relationship, care, compassion, and love permeates all that we are and all that we do, whether in person or online, in our thoughts, in our words, or in our actions, in how we spend our money or how we spend our time.
In other words, the Trinity demands that we are “absolutely available” to others, to be a loving and life-enhancing gift to them – to stand alongside them in their pain, to weep with them in their grief, to rejoice with them in their good news, to stand up against oppressive systems that dehumanise them, to shine the light of justice on those who misuse power, to call to account those who blindly ignore our groaning earth, to expose those who pedal lies and falsehoods, to speak up for those whose voices are silenced. After all, it is because God is the Trinity, because God is relationship, that Martin Luther King stated that life’s most persistent question, life’s most urgent and important question, is: “What are you doing for others?” So, I challenge you to reflect on your life and ask yourself that little question – “What are you doing for others?”
Through the Power of your Spirit,
And the Grace of your Son,
Help us to each to play our part in turning the world upside down
Through your compassion, care, peace, hope, and love.
