Rivers of Spirit: Spirit of Rivers – a reflection

On the last day of the festival, the great day, while Jesus was standing there, he cried out, “Let anyone who is thirsty come to me, and let the one who believes in me drink. As the scripture has said, ‘Out of the believer’s heart shall flow rivers of living water.’” Now he said this about the Spirit, which believers in him were to receive; for as yet there was no Spirit, because Jesus was not yet glorified. John 7:37-39

The above is one of the alternative readings given for Pentecost which thinks of the Spirit not as wind or fire, but as a river of water. 

Last Friday I took part in a thought-provoking event at St John’s Waterloo entitled Rivers of Spirit: Spirit of Rivers – https://stjohnswaterloo.org/tag/rivers-of-life/

 We began by going down on to the foreshore of the Thames where, like children, we looked at all the treasures on the little beach – shells and pebbles, smooth-worn glass, ends of clay pipes, rounded stubs of brick, sticks and pieces of bone. We sang and we prayed as, with increasing reverence, we were drawn to the sound and the movement of the river, to the ebbing-flowing tide – drawn to the Thames living presence.

From that reconnection with the river, we were more open to hear the wisdom of the afternoon’s speakers. 

Bishop Martin himself quoted from the passage from John’s Gospel, and talked about the living nature of water through the example of the eel. 

Eels are amazing creatures. They are laid as eggs in the Sargasso Sea from where they voyage by ocean currents some 6500km to reach Europe. During this first couple of years they develop from egg to glass eel. They leave the sea and swim inland up various rivers including the Thames, where they continue to develop becoming elvers and then yellow eels and finally silver eels – this can span from  5 to 20 years. Now they are mature enough to make the return journey to the Sargasso to begin the whole cycle again. Eels in the past were numerous in our rivers and a source of food for many (and not just humans). But due to the effects of climate change, pollution, loss of habitat  including from obstacles such as weirs and dams, their numbers over the last 40 years have declined  by a staggering 95-98%. (1)

God’s Spirit, like rivers of living water, is there to cleanse and refresh us. But what if we harden our hearts and do not seek forgiveness and renewal?

The first two speakers, Al Barrett and John White spoke about the importance of creating communities. Al Barrett is the vicar of the Hodge Hill Church in east Birmingham. John White is the founder of the Hazelnut Community and author of the Rooted in Rubble articles from which I have recently quoted.

Al spoke about creating ‘bumping places’ – places where parishioners from many and diverse backgrounds can meet and get to know and trust each other. He spoke how during Covid they ‘rediscovered’ the green places in the parish including the common. Commons have existed for hundreds of years as spaces designated for use by the community –  the commoners – who would have rights to graze animals, gather firewood etc. Where Commons remain today they are often important as essential green spaces for  local people and as essential habitats for wildlife. 

And Al described how finally he managed to ‘discover’ the River Tame which was barricaded out of sight and inaccessible to the community through which it flowed. 

John  spoke about how the Hazelnut Community’s  garden brings people together in the garden and in the gardening. Gardens root us and place us in a right relationship with creation.

Debbie Colvin described to us our place – our home – within the Thames basin which stretches from the Cotswolds to the estuary, from the Chilterns and northwards  to the South Downs. Within this area rainwater drains down to the Thames, but not just via stream and rivers, but also percolating down into  the strata deep below our feet where the water moves and buffers, hydrating the ground, feeding into springs and wells. A slow and measured process whereby rain falling on the hills of Reigate may take 10-20,000 years before reaching Trafalgar Square. (Prior to the 1930s the fountains in Trafalgar Square were fed by artesian wells (2)).

Paul Powlesland spoke about his life’s journey that finds him as a self appointed river guardian for the River Roding  and as the founder of the River Roding Trust. His love and respect of this river sees him clearing rubbish, planting willow and Black Poplar saplings and defending the rights of the river and the communities that live nearby. Called to jury service, Paul made his oath not on a Bible but on the River Roding, making this river a sacred thing, a being worthy of worship. (3) Much of this river, the third longest in London, is degraded – desecrated – by sewage, rubbish and pollution. Paul’s approach is hands on and includes pressing the Thames Water Authority to do its job properly. (4)

Paul himself  lives off grid on a narrow boat which means his life is intrinsically connected to that of the river and the environment. His awareness of the drought that we are currently facing, is measured by how much water remains in the rainwater that provides him with water. 

What struck me about the issues raised by these speakers was –

  • how little value we, as society, place on water,  
  • our lack of concern/ interest as to where our water comes from and 
  • our lack of concern as to whether it will be there in sufficient quantity in the future (humankind is extracting fresh water at a faster rate than the rate at which natural processes allow for replenishment (5)) 
  • our lack of concern for the health and wellbeing of our rivers – and not just our rivers, but the springs and aquifers from which they come, and
  • our lack of concern for the other living communities that depend upon rivers and the river environment.

At the same time, the speakers brought to mind way we might change our relationship with rivers:

  • looking at / treating rivers as living needs and rights, and 
  • as beings that give generously of themselves to our benefit, and further,
  • that maybe we should treat rivers as sacred –
  • and not just rivers, but all water. In the past wells were often considered as holy places so why not also taps and reservoirs today?

And from this came thoughts about what we might do as local communities and as churches.

  • Create a map that shows local rivers, streams and wells. 
  • Arrange pilgrimages to walk along or between these
  • To spend time in prayer and celebration in these places, to wonder and to rejoice.
  • Work out – maybe add to the map – where our drinking water comes from, and where it goes when we have used it
  • Find about local riverine habitats and whether they are in good or declining health.
  • To engage with – or establish – means of safeguarding and caring for wellbeing of your local river/ stream etc  – and allowing yourselves to benefit from its contribution to your wellbeing.
  • Identify our local water sources as sacred.
  • Arrange water blessings for local rivers, streams and wells and wells
  • Provide blessings for taps, drains and water butts
  • Encourage people to value water – to treat it as sacred and not as something to be consumed rashly or without consideration 
  • Encourage people to think about being less wasteful in the use of water. At current levels of consumption, we are likely by 2055 to see a shortage of 5 billion litres per day (6)
  • Encourage people to be aware of water cycles – seasonal changes, periods of rainfall and periods of droughts, of tidal cycles where appropriate. 
  • Encourage people to do even small scale gardening (cress seeds grown on blotting paper) to appreciate the importance of water in keeping plants – and therefore us too – alive.

“Campaigners warned [2019] that the clear waters of the Wye, one of Britain’s best-loved rivers, were being blighted by thick green algae blooms linked to poultry production. Many of the intensive chicken farms in the catchment area of the Wye supply Avara Foods in Hereford, which is the third largest poultry producer in Britain and is jointly owned by the American food business Cargill. It is claimed that vast amounts of manure from chicken farms supplying Avara and other food businesses are washed into the Wye, contaminating the water with excessive phosphate levels that fuel the growth of algae blooms…

Cargill has operated in the UK since 1955 and purchased a major poultry processing plant in Hereford, more than 40 years ago. In 2013 it announced a £35m investment in the plant to increase production of fresh chicken, and five years later it combined its fresh chicken operation in the UK with poultry business Faccenda Foods to form Avara. New intensive poultry units – each housing at least 40,000 chickens – sprung up to meet the demand, and between 2013 and 2017 the number of birds in Herefordshire increased from 13 million to 18 million. 

It is now hoped stricter controls and new practices, supported by Cargill and other operators, will help reduce the Wye pollution. Some farms are installing biomass boilers to generate heat from chicken manure, while other farms are sending the poultry litter to anaerobic digestion plants.” https://www.theguardian.com/environment/2022/sep/25/chicken-farm-giant-linked-to-river-wye-decline-was-sued-over-water-blight-in-us?CMP=Share_iOSApp_Other

How sustainable is our current meat focused diet? Is there scope for change that can create a better world?

Support campaigns for restoring rivers. Allowing rivers to follow their natural course rather than being dredged and straightened helps control flooding and provides a more secure habitat for river wildlife. Cleaning rivers of physical pollutants also helps prevent or limits the affects of flooding – wind blown and carelessly discarded plastic and other rubbish can block inlets and outlets and be a death trap for river wildlife. Cleaning rivers of chemical pollutants enables rivers once more to become vibrant places of biodiversity as well as becoming safe places to bathe!

Clean and biodiverse-rich rivers are rewarding places to spend leisure time and we are increasingly  aware of the health benefits of blue spaces. What’s not to like?

12 days of hope. 

Today’s Guardian reported on the rewilding of Swindale Beck: ‘For Schofield, an ecologist who is senior site manager at the RSPB in Haweswater, restoring the natural process to the beck was emotional work. “The stream as it was just looked like a canal, with stone banks and levees built up as time passed from years of dredging and dumping material on the sides. So we had to be quite interventionist ourselves, using diggers, creating a channel, removing spoil. For many conservation projects you do not see the results for a very long time, but with this one, we completed it on a Friday. It rained all weekend and on the Monday when we went to look at the beck, there was just this completely restored river, that curved and meandered and looked like it had been there for ever. It was a really powerfully emotional moment.” Within about three months, the rewards continued as salmon began spawning again in the gravel bed, made possible by the slowing down of the stream and the creation of still pools and shallows. Schofield said the restoration had improved numbers of common sandpiper, kingfishers, dippers and grey herons and increased the diversity of invertebrates in the stream.’

Similar rewilding projects are happening across the country including our nearby Beverley Brook. It’s name means beaver meadows indicating who used to inhabit its waters.

Much of the plastic that ends up polluting the oceans gets there via streams and rivers. And the plastic that ends up in the streams and rivers is either litter that has been thoughtlessly discarded or plastic that has fallen or been blown out of recycling bins. We can help in three ways – firstly not thoughtlessly discarding plastic (which I am sure we wouldn’t). Secondly by picking up litter and disposing of it safely. Thirdly by ensuring that the plastic in our recycling bins is flattened as much as possible and packed (eg stacking similar sized pots or trays together) so that there are no loose pieces that can easily be dislodged. Aim for a neat and condensely  packed  bin.

Pollution of our water system can begin at home. Only three things should go in the toilet – pee, poo and toilet paper. (Other paper, even things like paper serviettes shouldn’t be thrown down the loo – they are not designed to break down quickly and can cause blocked drains). Wet wipes, cotton buds, sanitary products, sticking plasters, dental floss etc should not be discarded via the toilet. NB You can biodegradable dental floss which can go into the compost bin. 

In the kitchen what goes down the drain should be limited to waste water and appropriate amounts of soap and cleaning fluids. Fat and oil (wipe excess up with a paper towel or piece of news paper) and food waste, including coffee grounds, should go into the food waste bin. Food waste and fat can block drains, and chemicals such as white spirit can cause pollution.
