Who Do We Obey? Augustine, Bonhoeffer, the Confessing Church, and the Guidance of Revelation

A choice between two cities


The book of Revelation is often treated as a puzzle about the future to be solved. But for the early church—and for Christians living under pressure—it functioned as something far more prescient: a guide and encouragement to be faithful when political power demands allegiance that belongs to God alone.

That is why the story of Dietrich Bonhoeffer and the Confessing Church matters so deeply for Christians today. Their struggle was not about partisan politics or policy disagreements. It was about lordship. Who has the right to command the Christian conscience? Who gets our obedience when the state demands what Christ forbids—or forbids what Christ commands?


When Obedience Becomes Worship

The crisis in Nazi Germany was not simply that the government was unjust. It was that the state demanded moral and spiritual loyalty. National identity became sacred. Political obedience became a virtue. Silence and complicity in the face of injustice was praised as faithfulness.

Scripture warns us that this is always how idolatry works.

“No one can serve two masters.” (Matthew 6:24)

In the City of God, St. Augustine contrasts the City of man and the City of God. We owe our allegiance to the City of God, though God calls us to live in harmony, as best as we can, with the City of man. Loving God is first, but loving man is like it. We cannot love God and fail to love people who God loves and created in His image.

Revelation is encouragement and exhortation to us when the City of man exhibits the characteristics of the beast. Revelation describes the beast as a power that compels allegiance to itself in everyday life through economic pressure, social belonging, and fear of exclusion:

“So that no one can buy or sell unless he has the mark.”

(Revelation 13:17)

The issue is not technology. The issue is worship – your heart, your devotion, your allegiance.


Bonhoeffer: Discipleship Is Visible

Dietrich Bonhoeffer saw clearly what many Christians hoped to avoid: there is no such thing as private faith when public injustice is at stake. Throughout the Prophets who repeatedly warned God’s people about coming judgment, the issues were twofold: idolatry and injustice.

Idolatry and injustice always go hand in hand. Augustine said that our true allegiance is revealed by what one loves, serves, and obeys.


“Two cities have been formed by two loves: the earthly by the love of self even to the contempt of God; the heavenly by the love of God even to the contempt of self.”

(City of God XIV.28)


Injustice always flows from misdirected worship – misdirected loyalty, priority, and desire. Augustine called injustice robbery, because it robs people made in the image of God of what God intends for them.

In The Cost of Discipleship, Bonhoeffer warned against what he famously called “cheap grace”—grace that forgives sin without transforming obedience. Transforming obedience is the kind of obedience that forsakes self-interest out of love for God and man.

“When Christ calls a man, he bids him come and die.”

That call is not only about personal holiness. It is about allegiance. Bonhoeffer understood that following Jesus means concrete obedience, even when that obedience is costly, unpopular, or dangerous.

Faith that quietly accommodates injustice, he argued, is not faithfulness at all. God “upholds the cause of the oppressed,” and “watches over the foreigner,” and “sustains the fatherless and widow….” (Psalm 144:6-9) That is God’s heart, and that character marks those who love and serve Him.


“Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen.”

1 John 4:20


The Confessing Church: Saying “No” to False Authority

In 1934, pastors and theologians gathered to issue the Theological Declaration of Barmen. Their message was simple and bold:


“Jesus Christ… is the one Word of God which we have to hear and which we have to trust and obey in life and in death.”


This was not abstract theology. It was a refusal to allow the state to define truth, identity, or moral obligation. It was a rejection of the idea that national destiny or political leaders could speak with the authority of God the Father. The City of man is not the City of God.

In the language of Revelation, the Confessing Church refused to bear the name of the beast. They chose instead to bear the name of the Lamb:

“They follow the Lamb wherever he goes.” (Revelation 14:4)


The Danger of Complicity

Later in his life, Bonhoeffer pressed further. He argued that the church sins not only by acting wrongly, but by failing to act when injustice reigns.

“Silence in the face of evil is itself evil.”

According to Bonhoeffer, Revelation 14 warns that worship of the beast is not limited to overt acts of loyalty. It includes participation in systems that oppose God’s justice—systems that reward conformity and punish faithfulness—systems that oppress the poor, needy, foreigner, widow, and orphan.

“If anyone worships the beast… he also will drink the wine of God’s wrath.” (Revelation 14:9–10)

This is not a threat meant to terrify believers. It is a mercy meant to awaken them. We must not give our allegiance and our heart to Empire – the beast in our age. We must give our hearts, desires, and allegiance to God alone.


Revelation as a Call to Endurance

Revelation does not tell Christians to seize power. Revelation gives us the hope that the Lamb who was Slain will prevail despite the chaos, injustice, and oppression that reigns in a world controlled the beast. The urgent message is to endure patiently and be faithful. (Rev, 13:10)

“Here is the endurance of the saints, those who keep the commandments of God and the faith of Jesus.” (Revelation 14:12)

Endurance means refusing to let fear, convenience, or comfort decide our allegiance or obedience. It means trusting that faithfulness matters, even when it costs us socially, economically, or personally.

Bonhoeffer lived—and died—by that conviction. We can too.


Why This Still Matters

The beast in Revelation does not always look monstrous. Sometimes it looks respectable. Sometimes it speaks the language of order, morality, and security. Sometimes it rewards the loyalty of silence.

The question for Christians has never changed: Who is Lord?

Revelation, Augustine, Bonhoeffer, and the witness of the Confessing Church remind us that allegiance is not just what we say—it is what we do, what we tolerate, and what we refuse.

“We must obey God rather than men.” (Acts 5:29)

What Is the Place of Christians in the World?

“By faith [Abraham] made his home in the promised land like a stranger in a foreign country; he lived in tents, as did Isaac and Jacob, who were heirs with him of the same promise.”

Apocaliptical scene to the Rome cityscape matte painting

I go back from time to time to the early “church fathers” for perspective. Most recently, I have focused on what we call The Epistle of Mathetes to Diognetus (the “Letter”). Even when translated from the Greek language in which it was written, the words and thoughts ring foreign to our American ears.

As I read this early Letter, I am impressed that Christians in the 21st Century have much to learn from 2nd Century Christians. They lived into the message of Jesus in ways that we seem to have long since forgotten

We don’t know who the author was. The Greek word, “mathetes“, merely means “student”. The person or ruling family to which the letter was written is also uncertain. We only know it was written in the early to mid 2nd Century.

The Church had grown slowly but steadily into the 2nd Century. Persecution ebbed and flowed around those early Christians, but they were more generally ignored and almost universally despised. In many ways, Christians were a complete oddity. They didn’t fit into the pagan (Greco/Roman) culture or the Jewish culture.

Christianity was centered in Jerusalem until the Roman war against the Jews and the destruction of the Temple in 70 AD. Christians scattered at that point, though Jerusalem remained one of many hubs of Christian life. The 2nd Century was a time of decentralization and spreading out throughout the Roman Empire and beyond – into areas of Africa and Asia, some of which were controlled by the Roman Empire, and some not.

According to the Letter, Christians were not physically, culturally, or linguistically distinguishable from the people in the many places in which they lived. They were distinguishable in other ways:

“But, inhabiting Greek as well as barbarian cities, according as the lot of each of them has determined, and following the customs of the natives in respect to clothing, food, and the rest of their ordinary conduct, they display to us their wonderful and confessedly striking method of life. They dwell in their own countries, but simply as sojourners. As citizens, they share in all things with others, and yet endure all things as if foreigners. Every foreign land is to them as their native country, and every land of their birth as a land of strangers.”

The Epistle of Mathetes to Diognetus
chapter 5

The most distinguishing feature of those Christians, according to the author of the Letter, was their “striking method of life”: they lived as strangers in their own countries. Though they were citizens in those countries, they “endure all things as if foreigners”.

We might be tempted to think that the “uprootedness” of early Christians was merely a product of rejection and persecution by non-Christians, but the Apostle Peter suggests otherwise: Christians are a “royal priesthood” and a “holy nation” who live as “foreigners and exiles” in this world. (1 Peter 2:9,11) This echoes the writer of Hebrews, who described all great people of faith as “foreigners and strangers on earth”. (Hebrews 11:13)

These passages in the New Testament epistles highlight a fundamental trait of Christians in the world at that time. But not just at that time; Jesus spoke to all his followers (including us) when he said, “[Y]ou are not of the world” (John 15:19), and, “My kingdom is not of this world.” (John 18:36)

How strange are these words and concepts to modern Americans! From the earliest days of our youth, we are taught about our freedoms and rights as American citizens. In contrast, 1st and 2nd Century Christians enjoyed some rights as citizens of the various countries in which they lived (maybe not as robust as the rights we enjoy), but they lived as if they had none. And, this was their “distinguishing “striking” feature as a people! It is what made them stand out.

They marry, as do all [others]; they beget children; but they do not destroy their offspring. They have a common table, but not a common bed. They are in the flesh, but they do not live after the flesh. 2 Corinthians 10:3 They pass their days on earth, but they are citizens of heaven.

the Epistle of Mathetes to Diognetus
chapter 5

Second Century Christians lived as if they were really not of this world. And, this “feature “striking method” of living was noticeable. They adapted and fit into their surroundings and culture wherever they lived, except for this one thing: they lived like they were not citizens of the countries in which they lived – even if they were actually citizens.

They were outsiders wherever they lived because they lived like citizens of heaven. They fit in wherever they went, but they stood out by their allegiance to loving God and loving others. How strange and foreign that may seem to us!
