Christianity and the State – Biblical Government, Politics & Religious Freedom

Introduction: Christians as Citizens of Two Kingdoms

The relationship between Christianity and the state is one of the most difficult issues for believers because Christians live in two realities at the same time. On one hand, Christians are earthly citizens. They live under governments, obey laws, pay taxes, work jobs, vote, raise families, and participate in society. On the other hand, Christians are not ultimately defined by any earthly nation. Their highest citizenship is in heaven, and their highest loyalty belongs to God.

This is why Hebrews 13:14 says, “For here have we no continuing city, but we seek one to come.” Christians may live faithfully within earthly nations, but they must never treat any earthly nation, government, or political system as their final home.

Because of this, Christians must take public life seriously without allowing politics to become their master. My personal position is that Christians should not separate faith from public life, because God’s law reveals the moral order by which human beings are called to live. However, Christians must also avoid turning the church into a tool of political power or allowing the state to control the sacred mission of the church.

The proper Christian approach is neither a sacred public square that forces one religion upon all people, nor a naked public square that removes religion from public life, but a civil public square where Christians faithfully witness to truth, justice, and the gospel while recognizing that their highest citizenship is in heaven.

The Early Church: Living in the World Without Belonging to It

One of the most powerful descriptions of the Christian relationship to society comes from the early church. The Epistle to Diognetus describes Christians as people who “dwell in their own countries, but simply as sojourners.” They participate in ordinary life, but they do not fully belong to the world around them.

The same passage says that Christians “obey the prescribed laws, and at the same time surpass the laws by their lives.”

This is an important foundation for Christian public theology. Christians are not called to be lawless rebels who reject all earthly authority. They are called to obey the law where obedience is possible. Yet Christian obedience goes beyond civil law because the Christian life is shaped by the kingdom of God.

The state may command outward behavior, but Christ commands the heart. Therefore, Christians should be good citizens, but they should also be more than good citizens. They should be holy people, loving people, truthful people, and courageous people.

God's Law and the Christian Responsibility to Public Life

This means that Christians cannot treat law as spiritually meaningless. In Scripture, God’s law reveals His character and teaches human beings what righteousness looks like. The law was given so that people might know the standard God requires.

God’s commands show that justice, mercy, holiness, truth, human dignity, and love are not merely private religious opinions. They are rooted in the nature of God Himself.

This is why Jesus tells His followers to “seek ye first the kingdom of God, and his righteousness” in Matthew 6:33. The Christian life begins with the kingdom of God, not with the kingdom of man.

Yet seeking first the kingdom does not mean ignoring the world. Rather, it means bringing every part of life, including public life, under the lordship of God.

Micah 6:8 also gives a clear picture of public righteousness when it says that the Lord requires man “to do justly, and to love mercy, and to walk humbly with thy God.”

Justice, mercy, and humility are not only private virtues. They shape how Christians should think about law, government, leadership, and society.

Why Christians Should Not Separate Faith from Politics

For this reason, I do not believe Christians should act as though faith and public life must be completely separated.

McQuilkin and Copan criticize this kind of compartmentalization when they discuss figures like John F. Kennedy and Mario Cuomo. Kennedy presented himself as a Democrat who happened to be Catholic, insisting that the church did not speak for him, while Cuomo personally disagreed with abortion but would not seek to curtail it publicly.

McQuilkin and Copan argue that this approach is an unfortunate departure from the Christian tradition, which has helped shape Western ideas about human rights, democracy, and many other human goods.

They write that Kennedy and Cuomo made the mistake of assuming that “special revelation or theology cannot give us genuine knowledge.”

This is a significant point. If Christianity is true, then it does not only give private spiritual comfort. It gives genuine knowledge about God, humanity, morality, justice, sin, and righteousness.

A Christian should not pretend that these convictions have nothing to do with public life.

Governmental Authority Under the Sovereignty of God

At the same time, Christian engagement with government must be grounded in humility and submission to God’s sovereignty.

Scripture shows that earthly government has real authority, but that authority is never ultimate.

In John 19:11, Jesus tells Pilate, “Thou couldest have no power at all against me, except it were given thee from above.”

This statement is powerful because Pilate appears to have political authority over Jesus, yet Jesus reveals that Pilate’s authority is borrowed. He only has power because God has permitted him to have power.

This does not mean Pilate is righteous. It means that even unjust rulers are not outside of God’s sovereign rule.

Christians can therefore respect governmental authority without worshiping it. Government has a place in God’s providence, but government is not God.

Render Unto Caesar: The Limits of Civic Duty

Jesus also teaches this balance when He responds to those who try to trap Him with the question of paying taxes to Caesar.

In Matthew 22:21, Jesus says, “Render therefore unto Caesar the things which are Caesar’s; and unto God the things that are God’s.”

This teaches that Christians have real civic duties. If believers live under a government, use its currency, roads, courts, protections, and civil order, then they should not act as though they owe nothing to that government.

Paying taxes and honoring lawful obligations can be part of Christian obedience. Caesar has a limited claim.

However, the second half of Jesus’ statement is even more important: give “unto God the things that are God’s.”

Caesar may receive taxes, but Caesar must never receive worship. The state may claim certain duties, but it cannot claim the conscience, the soul, or the final allegiance of the believer.

That belongs to God alone.

Romans 13 and Acts 5:29: When Christians Must Obey God Rather Than Men

This is why Christian submission to the government is real but not absolute.

Romans 13 teaches that governing authorities have a role in restraining evil and preserving order. Christians should not be anarchists who reject authority simply because it is secular.

They should pray for leaders, obey just laws, pay taxes, and seek the welfare of their communities.

Yet Acts 5:29 gives the necessary limit when Peter says, “We ought to obey God rather than men.”

When the government commands what God forbids, or forbids what God commands, Christians must obey God.

This does not mean Christians should be hostile or rebellious by nature. It means that the Christian’s final authority is always God.

Civil obedience is important, but divine obedience is supreme.

The Danger of the Church Becoming a Political Power

One danger in the relationship between Christianity and the state is allowing the church to become too closely tied to political power.

McQuilkin and Copan give a striking example in Pope Gregory VII, who claimed that “the pope alone may use the imperial insignia,” that “all princes should kiss his feet and his alone,” that he “may depose emperors,” and that he “may absolve the subjects of wicked rulers from their allegiance.”

This is an example of the sacred trying to swallow the secular.

When religious leaders begin claiming power over kings and rulers in this way, the church can become more concerned with domination than service.

The gospel can become confused with political control. Instead of pointing people to Christ, the church can begin acting like an empire.

Human Sinfulness, Political Systems, and the Corruption of Power

This danger exists because human beings are sinful. Even when people claim they want to build a righteous or equal society, power can corrupt the people at the top.

In theory, many political systems promise justice, equality, freedom, or unity. But in practice, sinful people often use those systems to gain control over others.

This is one of the problems with systems such as communism as it has been attempted historically in places like Russia and China.

The stated goal may be equality, but the person or party at the top often does not step down. Instead of creating true equality, the system can become a dictatorship.

The Christian doctrine of sin helps explain why this happens. The problem is not only bad structures; the problem is the human heart.

If sinners create a system and sinners run the system, then the system can become oppressive even when it uses the language of justice.

Totalitarianism and the Danger of Making Government an Idol

This is also why totalitarianism is so dangerous.

McQuilkin and Copan warn against totalitarianism and give examples such as Muslim sharia law, as well as certain forms of progressivism or political ideology that attempt to control public life completely.

The danger of totalitarianism is that the state begins to act like a god. It does not simply preserve civil order; it seeks to control all of life.

From a Christian perspective, this is deeply dangerous because no earthly government has the right to claim ultimate authority over human beings.

The state has a role, but it is limited.

When the state becomes ultimate, it becomes an idol. When politics becomes ultimate, it becomes a false religion.

The Sacred, Naked, and Civil Public Square

However, the opposite danger is also real.

Christians should not support a sacred public square that forces Christianity through the state, but neither should they support a naked public square that removes all religion from public life.

McQuilkin and Copan explain this balance by contrasting the sacred public square, the naked public square, and the civil public square.

They argue that Christians should avoid “a sacred public square that privileges one religious perspective,” but they should also reject “a naked public square that expunges all religion from public life.”

Instead, they advocate “a civil public square in which citizens of any faith or no faith can engage in public life within the framework of the Constitution.”

I think this is the best model for a free society like the United States.

Biblical Convictions and Moral Reasoning in Public Life

A civil public square recognizes that everyone brings moral convictions into public life.

Secular people bring their worldview. Religious people bring theirs. No one approaches politics from a completely neutral position.

The question is not whether morality will shape law; the question is which moral vision will shape law.

Christians should not be ashamed to speak from biblical conviction in public.

If Christians believe that every human being is made in the image of God, then that belief should affect how they think about abortion, poverty, racism, justice, crime, family, religious liberty, and human rights.

Faith that never touches public life becomes incomplete.

At the same time, Christians should not use the government to force conversion, worship, or church membership.

Coerced religion is not true faith. The gospel must be proclaimed, not imposed by the sword of the state.

The Constitution, Church-State Separation, and Religious Liberty

This is where the American constitutional framework is important.

McQuilkin and Copan argue that “absolute church-state separation was never intended.”

They point to the Constitution’s statement that “no religious test shall ever be required as a Qualification to any Office or public Trust under the United States.”

They summarize J. Budziszewski’s view by explaining that the government is not allowed to require religious tests for office, establish a national church, or prevent free worship.

This means that the government should not establish one official church, but it also should not silence religion.

Religious freedom means the church is free to be the church, and citizens are free to speak and act from conscience.

This protects Christians, but it also protects others. In a free society, Christians should defend religious liberty not only for themselves, but as a matter of justice.

The Mission of the Church in Society

The proper role of the church, then, is not to become the state, but to witness to the state and society.

The church should preach the gospel, disciple believers, worship God, teach truth, serve the poor, defend the vulnerable, and speak prophetically when the state violates justice or human dignity.

The church should form Christians who are truthful, courageous, merciful, humble, and morally serious.

This may have political effects, but the mission of the church is larger than politics.

The church’s greatest contribution to society is not becoming a political machine.

Its greatest contribution is forming people who love God and love neighbor.

When the church is faithful, it shapes citizens who care about justice, life, family, mercy, truth, and service.

A Personal Christian Manifesto for Faithful Civic Engagement

My personal manifesto is that Christians should be engaged but not enslaved, patriotic but not nationalistic, political but not captured by party identity, respectful toward government but obedient to God above all.

Christians should seek first the kingdom of God, obey just laws, pay taxes, pray for leaders, vote with biblical conviction, defend human dignity, and speak truth in love.

Christians should care about law because law teaches, restrains, and protects.

But Christians must also remember that law cannot regenerate the human heart. Only the gospel can do that.

Therefore, the church must speak to the state, but it must never become dependent on the state.

Christians should advocate for laws that reflect justice and human dignity, but they should not confuse political victory with the kingdom of God.

Conclusion: The Cross Before Caesar and the Kingdom of God Above All

In the end, Christians are citizens of earthly nations, but they are ultimately citizens of heaven.

Like the early Christians described in the Epistle to Diognetus, believers should obey the laws and yet surpass the laws by their lives.

They should be present in society without being absorbed by society.

They should render unto Caesar what belongs to Caesar, but they must never give Caesar what belongs to God.

The state may receive taxes, honor, and lawful obedience, but only God receives worship, final allegiance, and the lordship of conscience.

The Christian’s duty is to participate in public life faithfully, humbly, and courageously while remembering that the cross comes before Caesar, and the kingdom of God comes before every kingdom of man.
