Some Recommended Introductions to Christian Ethics

Sometimes the variety and range of options of books makes it difficult to know where to begin in the study of any given topic. Whereas a few years ago we would have had to rely on the personal recommendations of a friend or acquaintance, and what was available in our local library or bookstore, now the entire catalog of human knowledge is, seemingly, open to us at all points. This is really great, if you have a starting place in mind or an existing framework from which to begin. For those simply trying to get a toehold in a new topic, the options can be paralyzing.

This post was written because I have had several people ask me what books I would recommend to begin the study of Christian ethics. The list is based on my own preferences and those that I would recommend to people who are reasonably well-read and who share at least some of my presuppositions about the nature of Scripture and the truthfulness of orthodox Christianity. In other words, I am going to make recommendations that are consistent with an orthodox, evangelical Christianity. There may be significant books on philosophical ethics, Roman Catholic ethics, or some sort of modernistic Christianity that others might see as invaluable. However, my point is to lead people deeper into the mystery of faith in Christ Jesus, not toward the apparent brilliance of writers in another faith. There are many books about particular topics within ethics that are useful, too. I have selected these as introductions, not endpoints.

Mere Christianity, by C. S. Lewis

This in not a textbook on Christian Ethics, per se. However, in his defense of a basic, orthodox Christianity, Lewis writes about ninety pages of his apologetic work—about a quarter of it—on what amounts to Christian Ethics. This is helpful, because it demonstrates the integration of Christian Ethics into the broader theological ideas of Christianity. The way we live is an apologetic and it is a demonstration of what we truly believe. For those new in the faith, Mere Christianity is an excellent place to start when trying to figure out how to live morally.

An Introduction to Biblical Ethics, by David W. Jones

Biblical Ethics is a subset of Christian Ethics, but this is the place that many evangelical Christians would do well to begin. Absent from the book are discussions of the categories of philosophical ethics, because the assumption behind this volume is that the reader believes Scripture to be trustworthy as a source of moral authority. This is a volume that teaches readers to reason well from Scripture to moral application. Jones writes with clarity and grace, with a fine balance between demonstrated research and transparency to make this useful for beginners who are primarily interested in how to read Scripture better. This is lean on particular application to current events, but long on methodology.

Invitation to Christian Ethics, by Ken Magnuson

This 2020 volume is a good, current survey of the field of Christian Ethics from an evangelical perspective. Magnuson introduces various philosophical and theological frameworks for moral reasoning, but the focus is on reasoning well from Scripture. This is a book that is helpful if a reader is trying to figure out why different systems of moral reasoning end up with different ideas. After laying out his basic framework, Magnuson then moves on to discuss various contemporary ethical issues, working through them from a scriptural foundation.

The Doctrine of the Christian Life, by John Frame

Frame’s book is a hefty volume, but it is a solid way to begin an ethical journey. I love John Frame’s approach and have been deeply influenced by it. However, his triperspectivalism is distinct from many other approaches and likely to be less common in future years. I have a deep attachment to DCL and all of Frame’s work, but his approach will retain popularity primarily among conservative Presbyterians in the years to come. At the same time, if a reader is looking for a different approach to complement their understanding of Christian Ethics, Frame provides a deeply theological, Scripture-saturated book written from a Reformed perspective.

Ethics as Worship, by Mark Liederbach and Evan Lenow

This book is a 2021 volume that combines some features that I really like. It is a full introduction to Christian Ethics textbook, with a survey of various philosophical approaches. It is primarily driven by Scripture as the source of morally authoritative guidance for our age. Ethics as Worship includes application to many of the major, contemporary moral issues. All of this puts it in the solidly introductory camp and makes it quite useful. In addition, Liederbach and Lenow also have an explicit focus of living the moral life as an act of worship. This is a subtext in most evangelical ethics texts, but this book makes it overt. I’ve read it once and enjoyed it. I need to read it and use it more to fully evaluate it, but it is a good, useful book that I commend for its faithfulness, readability, and doxological emphasis.

Reformed Ethics, by Herman Bavinck

Volume 2 just released a few months ago. I haven’t finished it. However, volume 1 is clearly a treasure and I anticipate that the final two volume will continue the legacy. Bavinck is one of my favorite theologians. He does ethics from a theological framework in the Reformed tradition. His approach will connect well to Jones, Frame, and, to a reasonable degree, with Liederbach and Lenow. Bavinck is not going to cover contemporary issues, since he wrote a century ago. However, what you see is non-performative reasoning from someone who was grappling with modernity, outside our specific culture, and dealing with the same source text—Scripture—that we are using. His application requires a little translation, but this is helpful. Bavinck’s Reformed Ethics are a good historical approach that can be used to encourage thoughtful application of orthodox theology and scriptural reasoning in our day.

Resurrection and Moral Order: An Outline for Evangelical Ethics, by Oliver O’Donovan

This is the last book on this list for a reason. It is a very difficult book to read, but it is also very important. O’Donovan’s work is essential for a full understanding of what it means to think morally as a gospel-focused, theologically orthodox believer. This is a book that demands slow reading and often repeated reading. It was not until the third time through the book that it made sense to me, but once it ‘clicked’ everything fell into place and it helped unlock a more complete process of moral reasoning through Scripture. This is the Brothers Karamazov of Christian ethics; it is very hard work, but it is very much worth the effort.

This is not an evaluation of all the ethics books on the market. There are certainly others that are good and helpful. This is where I think someone should start as they seek to understand Christian ethics better.

The Ends Don't Justify the Means

The most destructive of ideas is that extraordinary times justify extraordinary measures. This is the ultimate relativism, and we are hearing it from all sides. The young, the poor, the minority races, the Constitution, the nation, traditional values, sexual morality, religious faith, Western civilization, the economy, the environment, the world are all now threatened with destruction—so the arguments run—therefore let us deal with our enemies by whatever means are handiest and most direct; in view of our high aims history will justify and forgive. Thus the violent have always rationalized their violence.

But as wiser men have always known, all times are extraordinary in precisely this sense. In the condition of mortality all things are always threatened with destruction. The invention of atomic holocaust and the other manmade dooms renews for us the immediacy of the worldly circumstances as the religions have always defined it: we know ‘neither the day nor the hour. . . .’

Wendell Berry published these paragraphs in 1972 in an essay called “Discipline and Hope”, but they could have been written yesterday. Maybe some of his examples would have changed, but the point is still valid.

Though Berry is still alive and the book is not quite old enough to count as an “old book” by Lewis’ definition, it is helpful to realize that about 50 years after these paragraphs were penned, the problem is still very much the same. It’s ok to be brutal to people on “the other side” because they are trying to destroy the SBC, the nation, the economy, the environment, Christianity, etc. The story is the same and so is the truth.

The truth is that it won’t matter much which side wins the culture war if the goodness of the culture is torn down to win it. Looking back, our children’s children will think we are fools and backward for a number of reasons that we can’t see and would never to think to recognize. They will look at some of the battles being fought and wonder why there was so much energy spent, when really the obvious problem was. . . .

But we can’t see what fills in that blank. And that is the nature of it. The very things that we do not question today because we can’t conceive of them being questioned will be the things that are assumed to be completely true or false (and obviously so) by a future generation.

As Christians we can see that there are many things wrong with this world and many people taking a wrong direction. But I can see the same thing in myself. The difference is that I can do something about myself and I have only limited influence on the rest of the world. My most significant influence on the world may be by living rightly in my own sphere of influence, showing people a positive way forward based on the truths of Scripture, and embodying those to the maximum extent possible. If the culture war is about goodness and truth, then so should our daily lives be.

The ends don’t justify the means. It is no good to win the culture war and lose our own souls, which is exactly we are risking. History may judge us all fools, and it may judge some on one side or the other of any issue as morally better than the others. But history isn’t the ultimate judge. God is. At the end of this life, our individual legacies will be laid before God. Our works will pass through the fire. Only those works wrought with faith, hope, and love will remain. The ends will be judged by the means.

We don’t know when the judgment is coming, but we Christians know the judge. We know his character. We have access to his standards through Scripture. We of all people should live like we know his judgment is coming, which should shape the way we fight our political battles today.
