Why read Martin Luther today?

Innovative ideas around identity shaped the world around him.

Tensions build as the German election approaches. Money is flowing, bargaining going on behind the scenes. (We are talking the election of 1519 here). There is the favorite, Karl—they called him Carlos in the Spanish dominions he had  inherited from his maternal grandparents, Ferdinand and Isabella—, grandson of the German emperor, Maximilian of Austria, and there is the challenger, the King of France, Francis I, and there is the wild card, the duke of Saxony, one of the seven electors who would elect the next emperor, Frederick, called the Wise.  Frederick had no imperial ambitions, and he tipped the election to his distant cousin, the then young man we call Charles V.  Two years later, that gave Frederick the leverage to win a hearing for his most prominent professor at the pride of his heart, his new university in Wittenberg, Martin Luther. 

Charles regarded this Augustinian friar, who had been excommunicated at the beginning of 1521 by Pope Leo X, as a dangerous heretic.  He wanted to declare Luther a criminal, open for execution on the open road by whoever might find him and run him through.  Frederick advised the young emperor not to treat a German subject like that, so Charles arranged for Luther to come to the imperial diet in Worms in May 1521 to recant.  Luther explained to the emperor that he really could not recant since his writings contained many truths.  He continued, “I am bound by the Scriptures I have quoted, and my conscience is captive to the Word of God.”  Later reports say that he added the words, “I cannot do anything else. Here I stand. God help me!”  Whether he said “here I stand” or not, that is what Martin Luther did at Worms and continued to do for the next quarter century until his death. 

Upon what was he standing?  As a “doctor in Biblia,” a “teacher of the Scriptures,” Luther had taken up the latest methods of the so-called humanist movement for exploring ancient texts in their original languages.  Jurists turned to Justinian’s Code in sixth century Latin. Physicians were reading Galen’s medical advice in ancient Greek. Theologians immersed themselves in the Bible in Hebrew and Greek.  Luther had put the tools of these methods to use as he lectured in the 1510s on the Hebrew Psalms, and then the apostle Paul’s letters to the Romans and to the Galatians.  There he found a new way of viewing himself, the God whom he found speaking to him in the pages of the Bible, and his fellow human creatures.  He used the world “righteousness” in the way we might use “personal identity” today.  He heard from the biblical writers a different way of identifying who he was at his core by listening to God’s regard for him.

Just as our DNA is a gift, not something we have to work to earn, so Luther’s core identity came from outside himself.

Luther certainly did not deny that human performance helps give each human being a variety of identities as we go about what he saw as callings from God in our exercise of responsibilities in our homes, in our economic life, in our societal networks and political structures.  He believed that in these spheres of life we are active in shaping the way other people view and identify us.  But at his core, Luther found the person behind the masks of his everyday life to be unable to perform everything that would make him the good person he wanted to be, the good person he thought God wanted him to be.  Just as our DNA is a gift, not something we have to work to earn, so Luther’s core identity came from outside himself.  It came as a gift from God, his Creator.  He received it passively, and his trust in the God who gave him this passively bestowed identity set his entire life in order.  Because he trusted God to be his support and to justify who he was, he felt freed to perform his responsibilities toward other human creatures actively. 

Luther believed that on his own he had not been able to trust God, to love him and give him proper respect.  Like the modern psychiatrist and philosopher, Erik Erikson, Luther believed that trust forms the basis of human personhood and personality.  He saw that his trusting some Absolute and Ultimate formed his character and enabled him to function as a human being.  He recognized in the God presented by the Old Testament prophets of Israel and the New Testament evangelists and apostles the ultimate and absolute person, who approached the human creatures who had turned their backs on him by becoming one of them as Jesus of Nazareth.  In the mysterious ways of the Creator, Jesus’s death covered the transgressions and offenses, the mistakes and failures, of all human beings, and in his resurrection God gave new life, a new identity, true righteousness to those who trust in him. 

Luther found that message liberating.  It freed him from being imprisoned in a cycle of always insufficient attempts to be the person he wanted to be to please his Creator.  He rested in the unconditional love of this Creator, who had come face to face with humankind as the rabbi from Nazareth, crucified but back from death itself.  That freed Dr. Luther to be bonded to those within his reach who needed his care and love.  He need not manipulate them by doing them the good he needed to make himself look good in God’s sight and feel satisfied with himself.  He now could do them the good that they truly needed.  That gave his tempestuous spirit a sense of joy and peace. 

He lived out a rather peaceable life under the ban of church and empire, but safely ensconced in the lands of his Saxon electors.  Family life brought him much joy.  His judgment that God had given human beings the gift of sexuality for companionship and support as well as procreation made him uncomfortable with his own vows of celibacy, but not so uncomfortable that he would have married had not a nun named Katharina von Bora, who had left the cloister, laid claim to him.  Together they created a bustling household with their six children being raised in the cloister where Martin had lived as an Augustinian Brother, large enough to house students and guests from places far from Wittenberg.  Katharina served as his counsellor and theological conversation partner as well as the efficient manager of this ever-changing parade of co-inhabitants of their home. 

Music filled their home.  Luther’s firm tenor voice and his lute and his flute led family and visitors in evenings of song, sometimes giving voice to hymns he had written.  His sense of tone and rhythm coupled with sensitivity to the fine points of spoken and written speech made him a scholar of great skill and a translator who “looked into the mouths” of the people in the marketplace and render the Bible in their tongue.  His curiosity stimulated or at least supported colleagues at the university across the disciplines, including a botany instructor who took students the woods to look at leaves and colleagues in mathematics and astronomy who were playing with the new calculation of the heavens by Nikolaus Copernicus. 

Luther’s lively engagement with life and his dramatic search for peace in the pages of the Bible produced a man who enjoyed life despite his struggles with “melancholy,” a widespread disease of his time, and the threats of violence to his person that never disappeared.  His robust wrestling with the biblical texts provides even today stimulating, even provocative reading for anyone, who is looking for the heart of the matter, the matter of self and life.

Living sustainably doesn’t have to be a burden, here’s the case for action

How not to get hot and bothered about climate change.

The fundamental tenets of Christianity show why Christians are called to love not just one another but all created things. 

1. God is love. 

2. God created everything. 

Therefore, God loves everything he created.  

3. God appointed humanity as the guardians of creation. 

Therefore, a fundamental part of our identity and calling as human beings is to protect and sustain all that God created. 

This lies at the basis of everything Christians believe and do. But a case can be made that is more basic still because it appeals, not to anything distinctively Christian, but to natural human wisdom. The climate crisis is not a Christian crisis. It’s a crisis for everyone who cares about their future and that of our planet. The climate crisis may be something unprecedented in the history of humanity, but the principles that are needed to resolve it are not new at all. Sustainability is not a new or particularly abstruse idea. It is something everyone understands as basic common sense. If I cut down trees faster than they can grow, I won’t be able to do that forever. One day I will cut down the last tree and then there won’t be any more trees, ever again. If I catch fish faster than they can reproduce, then one day I will catch the last fish and then won’t be able to catch any more ever again.  

But it’s not only about foresters and fishermen. Since the dawn of humanity, we have been living sustainably – wisely preserving resources and using only what we can replace, so that we and our descendants can continue to live. This applies to everyone regardless of their profession. All of us, if we spend more money than we earn, are living in a way that cannot last for long. If we use resources at a faster rate than we can replenish them, we will run into trouble at some point in the future. Every person possessed of reason and common sense knows this intuitively without having to be taught it. Only someone seriously deluded, foolish, or with some kind of mental health problem fails to understand the need for sustainability in order to have any kind of future at all, let alone a pleasant future. 

The call to live sustainably can lead us to feel burdened by a permanent sense of guilt, a feeling that we ought to be doing more than we are...

We are burning fossil fuels at hundreds of times the rate they can be produced. We are producing plastics that cannot be recycled, meaning we have to dump them in landfills that are growing all the time. We are pouring carbon dioxide into the air faster than anyone can take it out. All of these things mean that there is a time limit on the kind of lifestyles we are all leading now. If we carry on in this way, then one day we will cross a line from which there is no returning. As Mark Scarlata has pointed out, the solution cannot be technological. Even if we find a way to balance carbon outputs with inputs, we are only kicking the can further down the road. Our inability to live within our means will simply resurface somewhere else later on. The problem is spiritual, not technical.  

Everyone understands this at some level even if it’s the kind of truth from which we prefer to avert our eyes. The harder problem is to understand why this basic common sense isn’t proving effective. Why are we living collectively in a way that only a foolish or insane person would live, when most of us taken by ourselves are neither foolish or insane? 

The problem, at least in part, is that we are all entangled in systems that make it very hard for us to live sustainably. If I am an ordinary Brit living in an ordinary town or city, and I need to buy toothbrushes or nappies or cucumbers or strawberries, I go to the local supermarket: and the only options available are made of plastic or wrapped in plastic that will not decompose for 500 years, and often brought here from the other side of the world using huge amounts of carbon emissions. Most of us are busy people with limited financial resources. We don’t have the time to find sustainable alternatives and often they are too expensive even if we can find them. The societal structures that we live in limit the choices we have. The call to live sustainably can lead us to feel burdened by a permanent sense of guilt, a feeling that we ought to be doing more than we are, but also an inability to see how we could be doing more given all the pressures, needs and constraints on our time and money. 

Christians do not naively believe that God will sweep in and fix everything if we just wait. That would be to deny our responsibility, and it is not what hope means. 

We are all culprits in part, since we all contribute to non-sustainable living. But we are also partly victims of forces beyond our control, large cultural forces that shape and determine our actions more than we can imagine. We have very little power over those structural forces and currently things do not look good. Common sense principles aren’t working. The climate crisis is only getting worse. So, what do we do?  

It is at this point that Christianity has something special to offer to the problem. 

First, Christians are never called to be defeatist or to throw in the towel. This is because we are called to an enormous hope, a hope that surpasses understanding, a hope that the world cannot understand because it stands over against all the odds and all the possibilities. This hope is rooted in the conviction that our God is God Almighty, that he has not abandoned his creation, and that he has power to save. He is a saviour. He is the God of our salvation. This is the God we believe in. The climate crisis may look bleak right now, but Christians need never despair or become indifferent. If we do our small part, we can trust that God is in control of what is out of our control.  

Secondly, Christians believe that every human being is a free agent with the capacity to choose how he or she will act. Our freedom may be limited by the societal structures that shape and constrain our choices, but it is not destroyed. We can still make choices within those limits to buy and live more sustainably – anything from choosing a holiday destination within driving distance, to giving up beef (by far the worst food for carbon emissions). There is something all of us can do.  

Thirdly, Christians believe in a God who transforms hearts and lives, winning them to the power of the gospel and to a new way of living that is free of the shackles that this world – the structures of society – puts on us. This transformation is slow – slower than we would like it to be sometimes. We feel the shackles still gripping us at times. We are not expected to change everything all at once, to become holy overnight. Nevertheless, God gives us the power to change our lives, and to become part of the solution rather than part of the problem. The way towards sustainable living is not to try to change everything at once, but to ask: what one thing can I change in my daily lifestyle that would make it more sustainable? And then once we’ve mastered that and integrated it so we no longer even think about it and it’s just a default, then we can ask: what’s the next thing I can do? All of a sudden what looks like an unimaginable height of transformation, when it is broken down, becomes a series of manageable steps.    

Even if we do everything in our power, we cannot by ourselves avert a possible catastrophe. We are small players in a big game. Christians do not naively believe that God will sweep in and fix everything if we just wait. That would be to deny our responsibility, and it is not what hope means. Hope means the opposite: that we continue to fight to avert climate disaster even when it seems hopeless. Christians are called to be part of the solution rather than part of the problem. We are called to live in such a way that, if catastrophe comes, it won’t be because of us – to live in hope that our actions are meaningful and worthwhile and that we are in the hands of a God who is far more powerful than the most powerful forces in this world.
