Loving Nations Without Losing the Kingdom-Part 2
The first part of this essay argued that nations are no accident of history but a feature of God's good order. Humanity's attempt at a single borderless empire was judged at Babel, and out of that judgment God brought the nations into being. He fixed their boundaries, preserved them at Pentecost rather than dissolving them, and will gather them at the last, still distinct, into the city of God. The same Scripture that refuses the cosmopolitan dream of one sovereign humanity also refuses the tribal dream of a people defined by blood. A nation, biblically understood, is a covenant community under law, its membership a matter of allegiance rather than ancestry.
That conclusion leaves the practical questions still to be answered. If membership is covenantal, a stranger can be received into it, and we must ask how, on what terms, and within what limits. We must also ask how the people of God, whose deepest citizenship lies elsewhere, are to live as members of earthly nations at all.
Covenant and Assimilation
This covenantal understanding gives assimilation its proper ground. Here the two presuppositions reach their plainest test. Begin with the cosmopolitan premise that a nation is only a neutral container for whatever cultures happen to occupy it, and assimilation looks like erasure, an act of cultural violence. Begin with the biblical premise that a nation is a covenant community ordered to public justice, and the same assimilation looks like adoption, the welcome of a stranger into a shared life. If a nation is constituted by allegiance to a shared public order expressed in founding documents, legal traditions, and constitutional commitments rather than by ethnic descent, then assimilation is not cultural erasure but covenant adoption. The newcomer is not asked to change his blood, which is impossible, but to embrace the public creed, which is possible and is the historic biblical pattern.
Ruth did not become ethnically Israelite. She became covenantally Israelite, her confession an act of legal and spiritual adoption into the nation. The same was true of the mixed multitude that left Egypt, the Gibeonites who entered treaty with Israel, and the God-fearers of the New Testament who attached themselves to the synagogue. In every case membership came through covenantal commitment, not genealogical connection.
This cuts against both contemporary extremes. Against the ethnonationalist, it insists that assimilation is genuinely possible, because membership is juridical, not genealogical. The newcomer who embraces the nation's public covenant becomes a full member, not a permanent outsider tolerated but never truly belonging. Against the multiculturalist, it insists that assimilation is genuinely required, because a nation is not a neutral container for competing cultures but a covenantal community with a substantive public order that newcomers must enter. A nation without a shared public creed is not a nation but a territory.
The principle holds wherever nations are constituted by covenant rather than blood, and it bears directly on America. America is a nation by constitution, law, and civic covenant, not by race or ancestry. The Declaration's affirmation that rights come from the Creator, the rule of law, ordered liberty, and the moral framework that undergirds self-government together form the public covenant that defines the nation, a covenant sustained not by bare assent to principles but by moral formation and shared habits of obedience across generations. This covenant is juridical, not salvific. It is a political compact, not a confession of faith, and it remains under the judgment of God's higher law. Its legitimacy is derivative, measured by its conformity to that law rather than by autonomous self-definition. Within its proper sphere, though, it sets the terms of American membership.
Immigrants are not asked to become ethnically Anglo-Saxon. They are asked to become constitutionally American, to adopt the public covenant that makes the nation what it is. This is exactly what naturalization enacts, a sworn oath of allegiance to the Constitution and the principles it embodies.
Assimilation so understood is neither impossible nor oppressive. It is the means by which strangers become fellow citizens. It honors both the integrity of the nation and the dignity of the newcomer by treating membership as something that can be truly acquired rather than fixed by accident of birth. The ethnonationalist denies that it is possible. The multiculturalist denies that it is necessary. The biblical vision affirms both.
This does not mean cultural distinctives must vanish or that immigrants must abandon every trace of their heritage. Culture is the fruit of national life and develops organically over generations. What assimilation requires is not uniformity but covenantal unity, a shared commitment to the public moral order. Where an immigrant's heritage does not contradict that order, he is free to keep it. Food, dress, music, the language spoken at home, family customs, and countless other distinctives can persist for generations without threatening national unity.
Where an element of one's heritage contradicts the public covenant, however, it must be relinquished. The covenant judges the culture, not the reverse. One cannot swear allegiance to ordered liberty while holding to honor killing, caste hierarchy, or the subjugation of women. One cannot embrace the rule of law while keeping faith with tribal vendetta or clan justice. To adopt the covenant is to submit one's inheritance to its authority, keeping what is compatible and releasing what is not. This is not oppression. It is the ordinary cost of belonging to any covenantal community. Within that unity considerable diversity can flourish. Without it there is no nation at all.
Covenantal unity asks more than symbolic affirmation. It asks lawful enforcement within a defined jurisdiction. Laws must be applied, boundaries maintained, violations answered. A covenant without enforcement is mere sentiment. Nations have the right and the duty to establish and enforce their own legal order, immigration law included. To affirm national boundaries is to affirm, in principle, the authority to govern who enters them and on what terms. This essay does not pretend to settle the precise contours of policy. It offers theological orientation, not legislation. There is no biblical mandate for unrestricted immigration. The very idea of nationhood presupposes the authority to regulate membership through lawful entry, assimilation, and shared civic obligation. By the same covenantal logic, genuine assimilation is not only permitted but required. Immigrants who commit to a nation's public order, learn its language, share in its civic life, and embrace its fundamental moral commitments can and must be fully received as citizens. The standard is allegiance, not ancestry.
The Two Kingdoms
Christians carry all of this under a prior allegiance. Our first citizenship is in heaven (Phil. 3:20). The church transcends national boundaries even as she affirms their legitimacy. So Christians should be the first to welcome fellow believers from other lands, recognizing a unity deeper than any earthly bond. And the church must never be conscripted for nationalist ends. She serves a King whose kingdom is not of this world.
Yet heavenly citizenship does not cancel earthly obligation. Christians owe real obedience to earthly authorities within their lawful bounds. We pay taxes, honor rulers, and seek the welfare of the cities where God has placed us. The two kingdoms are distinct but not divorced. Love of the heavenly city is no excuse for neglecting the earthly one.
And no nation is ultimate. No nation is sacred. To affirm nationhood is not to divinize any particular nation. All nations stand under the judgment of God, America no less than Babylon. Rightly ordered patriotism loves one's country as a gift from God while refusing to make it an idol. The genealogical nationalist and the Christian cosmopolitan commit the same error from opposite directions, grounding ultimate political loyalty in ancestry or in a humanity abstracted from God. Only Christ is Lord.
The church's own existence already proves that unity in Christ does not require political unification. Believers from every nation gather at the same Table, confess the same faith, and await the same hope while remaining citizens of distinct earthly nations. Spiritual unity and political plurality stand together without contradiction.
Return, then, to the question that has driven this inquiry from the start. Two presuppositions stood opposed, the one holding humanity to be ultimately one and its boundaries arbitrary, the other holding the nations to be God's own ordering of the earth. The whole arc of Scripture renders its verdict between them. The cosmopolitan project, however refined its modern form, is still the project of Babel, the attempt to build human unity apart from God, to gather power in defiance of creaturely limits, to erase the boundaries the Most High has fixed. Scripture refuses it, and so must we. At creation the nations were intended, embedded in the command to fill the earth. At Babel false unity was judged and the plurality of peoples established. At Pentecost the nations were preserved rather than erased, as the Spirit spoke through every tongue. In the end they are healed, brought into the city of God with their glory and honor intact. We are not left to choose between globalist dissolution and ethnic absolutism. There is a better way, many nations formed by covenant and united in the worship of the one true God.
But the unity Babel grasped at by force is given at last only in a person. It is given in Christ, the Word made flesh, who was scattered from no city but cast outside one, crucified beyond the gate to gather a people to Himself. He did not make a name for Himself. He emptied Himself, taking the form of a servant and becoming obedient to death, and for that obedience He was given the name above every name, before which every tongue in every nation will one day confess that He is Lord. The tower could not reach heaven. Christ came down from it. What Babel tried to seize, He freely bestows, gathering from every tribe and tongue and people a kingdom that needs no wall to defend it and no name but His. Until He returns we live as citizens of two kingdoms, loving our earthly nations as gifts of His good order while fixing our eyes on Him, in whom the nations find their healing and their home.
