I am reading a book called Trinity by Roger Forster. Forster, bearded, successful early, kinda trendy, around forever, is the evangelical equivalent of Richard Branson. A little bit anyway.
Forster points out so helpfully that the classical Greek view of God–thanks Aristotle–was that because he was perfect, he couldn’t change.1 Being the Uncaused Cause, on that analysis, made you like a classic sculpture: a perfect 10, but made of marble.
Forster–whose learning is impressive even if he veers around a little like a car with a puncture–compares this cold Greek slab with the God of the Cappadocian Fathers. They joined a fourth-century theological ruck alongside Athanasius, pushing back the Arian heresy and making sure a trinitarian God was a mark of orthodox Christianity. Forster writes: ‘The doctrine of the the trinity is truly important because God is personal, He is communal, He is loving, He is altruistic – and He is all of those things forever and ever.’2
It so happens the Cappadocian Fathers were themselves a trinity: Basil of Cesarea; his younger brother Gregory of Nyssa; and their big friend Gregory Nazianzus.
They were an example of inspired and super-smart Christians fighting the mighty Greeks on their home ground–a battle which, a thousand years later, people we now know as scientists had also to do: people like the devout Johannes Kepler, who freed natural science from its Grecian obsession with the perfectly circular.
The Cappadocian Fathers saw the Trinity as a kind of dance: as Forster says, ‘where the partners move around one another, each giving way to the other and then changing the direction, or changing the lead, but each one always in perfect symphony and synchrony.’3. Their word for this was perichoresis, which is a word I look forward to you using when you next see a dance routine.
It is a lovely picture though: God interdependent in his self-sufficiency. No wonder, then, that the creation that sprang out of the divine bosom, if we believe it, was itself a perichoresis of mutual service and supply. We breathe out; plants breathe in. Male and female he created them. We are one body, with many members. Perichoresis is everywhere. Which is why human thriving is not centred on achieving alone but on belonging and contributing.
