• The oceans

• The earth’s core

• The soil?

The soil

• Overlooked, not just scientifically…

• Not the stuff of books, films, adventures

• Not even the setting of films

• Muck?

Page 11: Soil muck and/or mystery? - Science and Christian Belief · • e fruitful and multiply; fill the earth and subdue it. Rule over…. (Genesis 1: 28) • The LORD God took the man

Soil and space

• A good soil is approx. 50% space

– Cryptopores

– Ultramicropores

– Micropores

– Mesopores

– Macropores

• A poor soil has little space!

Soil and time

• Rocks – little change over time

• The atmosphere, the oceans – seasonal patterns

• The soil?

Page 13: Soil muck and/or mystery? - Science and Christian Belief · • e fruitful and multiply; fill the earth and subdue it. Rule over…. (Genesis 1: 28) • The LORD God took the man

The soil in space and time

… in space: local, determined by geology, geography

… in time: continually changing – a by-product of biological life

The soil is alive!

‘dynamic interaction’, ‘mediator ‘

Pedosphere (along with the lithosphere, the atmosphere, the hydrosphere and the biosphere)

Page 14: Soil muck and/or mystery? - Science and Christian Belief · • e fruitful and multiply; fill the earth and subdue it. Rule over…. (Genesis 1: 28) • The LORD God took the man

…‘the most mysterious place on Earth is right beneath our feet’

A few facts:

bacteria –

1g soil contains 1,000,000,000 individuals!

...belonging to at least

10,000 different species!

… ‘the microscopic biota that till the soil’

Page 17: Soil muck and/or mystery? - Science and Christian Belief · • e fruitful and multiply; fill the earth and subdue it. Rule over…. (Genesis 1: 28) • The LORD God took the man

The wonder of soil

• At its most basic it brings together physics and chemistry, as well as biology

• Ritz et al (2009)

‘… soils are amongst the most complex systems on the planet’

‘… the majority of soil processes are driven by the soil biota.’

Page 18: Soil muck and/or mystery? - Science and Christian Belief · • e fruitful and multiply; fill the earth and subdue it. Rule over…. (Genesis 1: 28) • The LORD God took the man

Threats to the soil

• Erosion – by water or by wind

• Compaction

• Salinity

• Pollution

• Urbanisation Hodson & Hodson (2015)

A Christian guide to Environmental Issues

• Agriculture

Threats from agriculture

• Cultivation ‘burns off’ CO2

reducing organic matter

• Crops remove nutrients

exhausting the soil

Growing crops:

– What is the crop requirement for nutrients & water?

Rather than:

– What does the soil require?

Ch. 11 Spiritual aspects of sustainable soil management

Ch. 12 Theological and religious approaches to soil stewardship

Ch. 11 Spiritual aspects of sustainable soil management Bruce C Ball

• Refers to White (1967) – Christianity is responsible for humanity’s exploitation of nature and damage to the environment

• Also credits White (1967) with believing that the solution was also largely religious

• Summary of Ball’s view: ‘Science, agriculture and humanity need to become more and more connected to approach sustainability, and this can be made possible by engaging the spirit.’

• Vision: ‘a renewed world ..where we care for our environment by consuming less, becoming more self-sufficient, and living more simply, but with inward richness, like soils dark with organic matter.’

• For him spirituality is about being interconnected with everything and being aware of it. He quotes McLaren (2010)’s four basic characteristics of spirituality.

• In discussing Hildegard von Bingen’s appreciation of the soil, he commented that she attributed its ‘greening power’ to the Divine.

• Essentially he advocates appreciating the soil using all our senses as the basis for sustainable soil management.

Ch. 12 Theological and religious approaches to soil stewardship

Gregory E Hitzhusen, Gary W Fick and Richard H Moore

• ‘soil science alone cannot inspire global soil stewardship’

• They argue that religion may provide:

‘... soil-specific prescriptions of varying contemporary salience’

‘... fundamental principles that shape perspectives on the relationships between humans, soil and the divine or spiritual realm’

• They explore in detail Genesis chs 1 – 3, and go on to mention Noah, and the inclusion in Jewish Law of distinct Sabbath instructions regarding agricultural practice, concluding that the Bible paints a picture of humans as caretakers, as stewards of land, with ‘soil stewardship and agriculture used as direct reference points to illuminate this human vocation’.

• They look briefly at principles and texts from other religions

Page 28: Soil muck and/or mystery? - Science and Christian Belief · • e fruitful and multiply; fill the earth and subdue it. Rule over…. (Genesis 1: 28) • The LORD God took the man

Examples of stewardship growing out of faith

• Kayapo people in Brazil

• Amish collaboration with agroecologists

• Soil Stewardship Sunday in the US

• Farming God’s Way in Kenya

• ECHO (Educational Concerns for Hunger Organisation)

• Komemiyut village, Israel

• Tangier Island watermen, Chesapeake Bay

Not just quaint anecdotes but a corrective to the hubris that desires human control of everything

Soil in the Bible Genesis 3: 17-19

To Adam he said, “Because you listened to your wife and ate fruit from the tree about which I commanded you, ‘You must not eat from it,’ “Cursed is the ground because of you; through painful toil you will eat food from it all the days of your life. It will produce thorns and thistles for you, and you will eat the plants of the field. By the sweat of your brow you will eat your food until you return to the ground, since from it you were taken; for dust you are and to dust you will return.”

Genesis 4:

… Cain worked the soil.

… Cain brought some of the fruits of the soil as an offering to the Lord.

Genesis 9:

Noah, a man of the soil, proceeded to plant a vineyard.

Exodus 23, 34; Deuteronomy 26:

“Bring the best of the firstfruits of your soil to the house of the Lord your God.

Job, Isaiah, Ezekiel:

2 Chronicles 26: Uzziah King of Judah

…. he loved the soil.

Matthew 13: The Parable of the Sower

Then he told them many things in parables, saying: “A farmer went out to sow his seed. 4 As he was scattering the seed, some fell along the path, and the birds came and ate it up. 5 Some fell on rocky places, where it did not have much soil. It sprang up quickly, because the soil was shallow. 6 But when the sun came up, the plants were scorched, and they withered because they had no root. 7 Other seed fell among thorns, which grew up and choked the plants. 8 Still other seed fell on good soil, where it produced a crop—a hundred, sixty or thirty times what was sown.

C. S. Lewis on prayer Petitionary prayer is, nonetheless, both allowed and commanded to us: “Give us our daily bread.” And no doubt it raises a theoretical problem. Can we believe that God ever really modifies His action in response to the suggestions of men? For infinite wisdom does not need telling what is best, and infinite goodness needs no urging to do it. But neither does God need any of those things that are done by finite agents, whether living or inanimate. He could, if He chose, repair our bodies miraculously without food; or give us food without the aid of farmers, bakers, and butchers; or knowledge without the aid of learned men; or convert the heathen without missionaries.

His creatures the dignity of causality.” But not only prayer; whenever we act at all He lends us that dignity. It is not really stranger, nor less strange, that my prayers should affect the course of events than that my other actions should do so. They have not advised or changed God's mind—that is, His over-all purpose. But that purpose will be realized in different ways according to the actions, including the prayers, of His creatures.

On being the image of God ‘image’, ‘likeness’ = statue?

ANE rulers set up statues to show their subjects who ruled them

Are we God’s ‘statues’ showing the world that He is ruler?

Understandings of the image of God:

• Functional – ruling over creation as God’s representatives?

• Relational – humans can only fulfil this function if they live in a right relationship with the God they represent

• Structural – humans must have the attributes needed to ‘image’ the nature of God and to do the task God has given us.

Concluding remarks Humanity’s aims: • Problem solving, e.g. climate change, soil erosion • Economic growth • Peace, justice, wealth and health for all

God’s aims: • Be fruitful and multiply; fill the earth and subdue it. Rule over….

(Genesis 1: 28) • The LORD God took the man and put Him in the Garden of Eden to

work it and take care of it. (Genesis 2: 15) • Cursed if the ground because of you; …. until you return to the

ground…. (Genesis 3: 17b-19) • The creation waits in expectation for the children of God to be

revealed. The creation itself will be liberated … and brought into the glorious freedom of the children of God. (Romans 8: 19-21)

Our aim:

• To appreciate, to value, to care for, to enable creation to achieve its potential

Is soil muck or mystery? What do you think?

We are made of the same stuff:

• Atoms, molecules

• DNA, and everything downstream that makes us a Carbon-based life-form

• …’dust to dust’

Our lives’, as well as creation’s, purpose is ‘fruitfulness’ (Ian Paul)

Soil is the fruit of the labour of the soil fauna and flora
