How Christianity Built the West, and Why the Church Must Defend It

In 390 AD, when the Roman Empire was officially Christian but still governed by imperial habits, in the city of Thessalonica, a riot led to the killing of a Roman military commander. In retaliation, the emperor Theodosius I ordered a punitive operation. The soldiers sealed the city’s hippodrome and slaughtered thousands of civilians, men, women, and children, many of whom had nothing to do with the original unrest. By Roman standards, this was not extraordinary. Collective punishment had long been an accepted tool of imperial control.

When the emperor later attempted to attend church and receive communion, Ambrose, the bishop of Milan publicly refused him entry. The bishop insisted that mass killing, even when ordered by the state, was a moral crime requiring public repentance. The emperor was compelled to lay aside his imperial insignia, confess wrongdoing, and submit to a period of penance before being readmitted.

For the first time in Roman history, a ruler was treated as morally accountable not to another ruler, but to a transcendent standard enforced by the Church. The state was no longer morally self-justifying. This moment permanently altered the moral architecture of Western politics.

This shift had far-reaching consequences. Once political authority could be morally judged, the lives of ordinary people began to matter in ways they never had before. In classical antiquity, human worth was tied to status. Slaves were property. Abandoned infants were disposable. The sick and disabled survived at the mercy of private charity, if at all. The state did not see them.

Christian leaders forced them into political visibility. Bishops preached relentlessly against infanticide and exposure, condemning the practice of leaving unwanted newborns to die. Over time, laws were changed. Imperial edicts began to treat the killing or abandonment of infants as crimes. This was theological interference: the belief that every human life, regardless of usefulness, bore moral weight.

The same logic reshaped public care. The ancient world had temples and bathhouses, but no hospitals in the modern sense. Care for the sick was private, often familial, and limited by means. Christian communities, driven by the conviction that caring for the suffering was a public duty, established the first hospitals. Eventually, emperors began funding and regulating these institutions. Politics did not invent compassion; it adopted it under pressure.

Violence, too, came under constraint. Roman justice relied on spectacle. Executions were public, humiliating, and deliberately cruel. Crucifixion was the clearest example: a slow, degrading death designed to terrify. Once the cross became the central symbol of Christian worship, this punishment became morally indefensible. It was abolished because cruelty had lost legitimacy. A society that worshipped a crucified God could no longer justify crucifixion as routine policy.

Perhaps the Church’s most enduring political interference was its insistence that belief could not be coerced without being corrupted. Therefore, modern ideas of religious liberty, free expression, and limits on state ideology did not emerge despite Christianity. They emerged because Christianity made inner conviction morally non-negotiable.

Throughout the medieval period, the Church continued to intervene in political life, and in doing so helped shape the foundations of the Western world. Over time, the legal and moral principles that emerged from Christianity were secularized, systematized, and eventually universalized, extending their influence far beyond the West and shaping the architecture of the modern global order. For a detailed treatment of this process, see my separate paper on the nature of law.

The Judeo-Christian

Christianity did not invent the moral critique of power; it inherited it. The framework that later allowed bishops to confront emperors, limit violence, elevate the weak, and restrain the state was already embedded in the biblical vision of law, authority, and human worth.

In the Hebrew Scriptures, political power was never treated as morally autonomous. Kings ruled, armies conquered, and taxes were collected, but authority was always provisional. It was understood to be delegated, not possessed. Power flowed from God, and because it flowed from God, it could be judged by God. This alone separated biblical political thought from every surrounding culture.

In the ancient Near East, religion existed to legitimize power. Israel’s system was structured differently. Alongside kings stood prophets whose sole function was to speak judgment into political life.

When King David abused his authority by taking another man’s wife and arranging the man’s death to conceal it, he was confronted publicly by a prophet who forced him to recognize the moral weight of his actions.

That logic runs through the entire biblical narrative. Kings are repeatedly condemned for excessive taxation and economic exploitation (1 Samuel 8:10–18), for seizing land and abusing royal prerogative (1 Kings 21), for conscripting labor and wealth to serve dynastic ambition (1 Kings 12:4), for waging wars untethered from justice (Isaiah 1:15–17; Amos 1–2), and for manipulating religious authority to secure political loyalty (1 Kings 12:26–33). Law is consistently framed not as an instrument of control but as a measure of justice, binding ruler and subject alike (Deuteronomy 16:18–20). The weak are not treated as politically marginal but as morally central: widows, orphans, foreigners, and the poor function as a standing test of legitimacy (Exodus 22:21–24; Deuteronomy 10:17–19; Isaiah 10:1–2). A ruler’s success is judged not by expansion or stability, but by faithfulness to justice (Psalm 72; Jeremiah 22:13–16).

Church and Politics

Historically, several distinct theological approaches to the Church’s involvement in politics emerged, each shaped by specific historical conditions and producing different modes of engagement.

The earliest position was moral authority without political control. This view dominated late antiquity, when Christianity had gained legal status but did not yet govern states. Church leaders understood their role as prophetic rather than administrative. They confronted rulers, judged actions, and defended victims, but did not seek to replace civil authority.

This approach is visible in the writings and actions of figures like Augustine of Hippo (354–430). Writing after the sack of Rome in 410, Augustine rejected the idea that any political order, Christian or otherwise, could be equated with divine rule. The state existed to restrain violence and maintain order, not to redeem humanity. Yet rulers were still accountable to justice and could be condemned when they abused power.

A second position developed as the Roman world fragmented and political authority weakened: integration of church and state authority. As imperial structures collapsed in Western Europe, the Church increasingly filled administrative, legal, and educational roles. Bishops became governors. Kings relied on clerics to run their realms. Theology and law merged.

By the early ninth century, rulers such as Charlemagne (crowned emperor in 800) understood political power itself as a Christian vocation. Law codes, education reforms, and public morality were explicitly shaped by Christian teaching. Under this model, church interference was direct and structural. The state was expected to serve Christian ends, and the Church participated openly in political administration.

The Reformation introduced a fourth position: separation of institutions combined with moral responsibility of rulers. Reformers rejected medieval fusion of church hierarchy and political rule, but they did not accept political neutrality.

Martin Luther (1483–1546) articulated what became known as the “two kingdoms” doctrine. The Church governed conscience through preaching and sacrament; the state governed behavior through law. Yet the state remained accountable to God and obligated to protect justice, restrain evil, and care for the vulnerable.

In Geneva, John Calvin (1509–1564) advanced a more interventionist model. While rejecting papal supremacy, Calvin insisted that civil law should reflect moral truth. Economic exploitation, sexual conduct, public order, and care for the poor were treated as legitimate political concerns shaped by Christian ethics. The Church did not rule the city, but it defined the moral framework within which law operated.

Alongside these mainstream positions emerged a radical alternative: withdrawal from political authority altogether. Anabaptist communities rejected participation in government, military service, and public office, viewing the state as inherently coercive. While this preserved moral purity, it abandoned political responsibility and had little long-term influence on state formation.

Over time, this radical alternative, which began as a marginal position, hardened into a default posture. The Church did not formally renounce its historical role in shaping political life; it simply ceased to believe it could do so without corruption. Public engagement came to be treated as a liability rather than a vocation, a compromise rather than a responsibility. In the process, the theological confidence that once justified confronting kings, restraining law, and judging power eroded into silence.

The very theological principles that had shaped Western political order were reinterpreted as reasons for retreat rather than engagement. The Church did not merely step back from power; it stepped back from the public defense of the moral framework it had built. What was once a prophetic distance from the state became a principled absence from the public square. And as that absence normalized, the West became prepared, once again, to be shaped by whatever moral system proved most willing to rule in Christianity’s place.

The Cost of Christian Absence

When the Church withdraws from political life in order to avoid being stained by it, the result is not neutrality but displacement. The moral space the Church once occupied does not remain empty. It is filled, inevitably, by whatever framework is most capable of organizing power, shaping law, and disciplining society. Politics does not wait for theology to return. It proceeds without it.

As churches increasingly retreat into private spirituality or limit their public role to soteriological purposes or charitable work, the Christian moral principles that once shaped law and policy are left without defenders. Those principles are weakened, fragmented, and gradually displaced. In the absence of sustained Christian engagement, other moral systems step in to translate their own values into law, education, and governance, reshaping society by bureaucratic default.

What is labeled “woke” ideology did not arise because society became excessively political, but because it became morally unguarded. Policy itself is not ideological; it is receptive. It reflects the moral frameworks of those who are present, organized, and willing to translate conviction into law, education, and institutional norms. As the Church gradually withdrew itself from the public square it left that space open.

The Church’s withdrawal from public engagement is often defended as an attempt to avoid coercion or political compromise. Yet the effect is frequently the opposite. This does not imply that the Church should govern, legislate, or dominate political institutions. It does demonstrate, however, that the Church cannot vacate the public moral sphere without consequence. When it declines to contribute moral judgment to law and policy, it leaves those domains to be shaped by whatever moral frameworks are willing to do so.

The Replacement of Western Political Order

The space abandoned by Christianity in the modern West has not remained empty. It has been occupied, systematically and predictably, by alternative moral systems that are far more willing to translate their convictions into power. What we are witnessing today is not a coincidence, nor a sudden radicalization of society, but the cumulative result of a long retreat: first imposed on Christianity from without, and later accepted from within.

By the late nineteenth century, Western elites had already begun the deliberate project of pushing Christianity out of the public square. Moral authority was relocated from transcendent truth to historical progress, scientific rationality, and eventually to individual autonomy. Christianity was no longer regarded as the source of the West’s moral architecture, but as a relic of its pre-modern past.

What began as external pressure became internalized. Over time, the Church relinquished it’s public authority. In an effort to avoid conflict, corruption, and association with power, Christianity increasingly accepted the terms imposed upon it. It agreed to speak in private while remaining silent in public. Theology was preserved as spirituality, but surrendered as moral grammar.

Postmodernism dismantled the idea of objective truth, reducing knowledge to power relations and narratives. Moral relativism replaced shared standards with subjective preference. Human nature was redefined not as something given, but as something constructed. Gender ceased to be understood as a biological or metaphysical reality and became an act of self-definition. Justice was no longer tethered to moral order, but to identity and grievance. Authority was no longer restrained by truth, but justified by claims of victimhood.

Today, political Islam has joined the Left in further reshaping Western society. Though their ultimate aims differ, both reject the Judeo-Christian moral inheritance of the West, deny the legitimacy of the political order Christianity produced, and regard liberal constitutionalism not as a civilizational achievement to be preserved, but as a structure to be deconstructed.

The Islamic doctrine of al-ḥākimiyya, the belief that sovereignty belongs exclusively to God and that human legislation is legitimate only insofar as it enforces divine law, renders secular governance fundamentally illegitimate. Under this framework, democracy is not flawed but idolatrous. Human rights are not universal but conditional. Freedom of conscience is not a right but a rebellion against divine authority.

Sayyid Qutb articulated this logic in the mid-twentieth century. For him, any society governed by human law, even a Muslim-majority one, was living in jahiliyya - a state of ignorance and rebellion against God. Participation in secular systems was permissible only as a means toward their eventual replacement. Coexistence was not the goal. Supremacy was.

This is why the alliance between Islam and the Left is temporary by nature. The Left seeks the deconstruction of Western civilization. Islam seeks its replacement. Once the moral and institutional foundations built by Christianity are sufficiently weakened, the logic of al-ḥākimiyya cannot coexist with progressive relativism. The same certainty that makes Islam a useful ally against the West makes it an inevitable adversary of the Left.

Church of Christ, Rise

As an atheistic Left seeks to deconstruct the moral foundations of the West, and a tyrannical theism advances a rival vision determined to replace it, the civilization Christianity built is being hollowed out from both sides. In this contest, the Church cannot remain absent without becoming complicit. When the Church refuses to defend that inheritance in public, it leaves the work of moral translation to those who reject it entirely.

The task before the Church is not to seize power or govern states. It is far more demanding. It must recover confidence in the civilizational achievement its theology made possible and reenter public life as a moral witness. That means defending the legitimacy of the West’s political order, articulating why its laws and freedoms exist, and resisting ideological systems that seek either to dissolve them or replace them outright.

This requires the Church to leave the safety of the building and reengage the public square, not as a lobby, not as a culture warrior, but as the bearer of a moral vision capable of sustaining a free society. The West will not be saved by politics alone. Politics can preserve only what it understands and values. It was the Church that once taught the West how to limit power, honor conscience, and defend the weak. If those principles are to survive, the Church must again believe they are worth defending, and act accordingly.

What the Church Must Do, Practically?

If the Church is to defend the civilization its theology built, it must move beyond reaction and recovery toward deliberate reconstruction. This requires more than statements, sermons, or episodic engagement. It requires sustained formation, intellectual, moral, and institutional.

Christians must be educated not only in doctrine and devotion, but in how biblical theology built the West.

The Church must directly challenge the assumption that all cultures are ethically equivalent. Christianity does not merely offer one tradition among many. It offers a coherent ethical framework that has proven uniquely capable of sustaining freedom and elevating the weak without collapsing into tyranny.

The Church must help Christians understand the ideologies actively working to deconstruct or replace the moral order Christianity built. This includes progressive ideologies that deny objective truth and Islamic politics that deny legitimate civil sovereignty.

The Church must move beyond treating faith as private belief and return to shaping moral imagination. Christianity historically formed people who could recognize injustice, resist coercion, and defend institutions without becoming ideologues themselves.

The Church does not need to govern states or endorse parties to influence society. It must, however, speak publicly, consistently, and unapologetically about why Western law, freedom, and institutions exist, and why they are worth preserving.

The Church cannot call Christians to public courage while apologizing for the civilization Christianity produced. Confidence must precede action. Christians must once again believe, truthfully, that the Judeo-Christian moral framework produced something historically exceptional and morally superior to its alternatives.
