Jeremiah stood at the gate of the temple and spoke to people who were certain they were safe.
They had the house of the Lord. They had the sacred city. They had religious memory, national identity, priestly tradition, sacrifices, prayers, and language that sounded faithful. Jerusalem was not merely a political capital. It was the place where the temple stood, where worship centered, where the people believed God’s presence guaranteed protection.
But Jeremiah saw what they refused to see.
The people had turned the temple into a shield. They had made sacred language a hiding place. They believed the presence of religious symbols could protect them from the consequences of covenant rebellion. So the prophet stood at the gate and shattered their false confidence.
“Don’t trust in lying words, saying, ‘The temple of Yahweh, the temple of Yahweh, the temple of Yahweh, are these’” (Jeremiah 7:4).
It was a devastating warning. The temple was real. God had ordained worship. Jerusalem mattered in Israel’s story. But the people had mistaken possession of sacred things for obedience to the Holy One. They assumed they could steal, murder, commit adultery, swear falsely, worship other gods, oppress the vulnerable, and then stand in the Lord’s house as if His name were a covering for their sin.
That is what makes Jeremiah 7 so relevant now.
The danger did not die with ancient Judah. People still know how to hide behind sacred words. Nations still know how to dress self-interest in holy language. Leaders still know how to use God-talk to sanctify power. Crowds still know how to confuse public religious identity with actual faithfulness to God.
This is where the story of Jeremiah speaks directly into the modern conversation about Christian nationalism.
What Christian Nationalism Is Not
Christian nationalism is not the same thing as loving your country. It is not the same thing as praying for leaders. It is not the same thing as voting according to Christian convictions. And it is not the same thing as wanting laws to reflect moral wisdom. Faithful Christians can participate in public life, serve their communities, honor what is good in their nation, and seek justice through civic means.
The Bible does not require believers to withdraw from public responsibility. Joseph served in Egypt. Daniel served in Babylon. Esther acted courageously in Persia. Paul appealed to his Roman citizenship. Christians can love their neighbors through civic engagement.
But Christian nationalism is something different.
In contemporary discussion, the term is often used to describe the merging of Christian identity with national identity, especially when Christianity is treated as something the state should privilege or enforce. The Christians Against Christian Nationalism statement describes Christian nationalism as seeking to merge Christian and American identities and warning that it can distort both Christian faith and constitutional democracy.
That distinction matters. This is not an issue of whether Christians should care about public life. The issue is whether the name of Christ is being used to protect national pride, excuse sin, bless power, or imply that one nation has a special covenant status that belongs only to God’s redemptive purposes.
Jeremiah’s warning helps us see the difference.
The people of Judah were not wrong to value the temple. They were wrong to trust the temple while living fully in sin and refusing repentance.
Likewise, Christians are not wrong to care about their country. We are wrong when we use Christianity as a shield for national sin, political idolatry, racial pride, cruelty, deception, or lust for power.
The Lie Judah Believed
Judah’s false confidence sounded religious.
“The temple of Yahweh, the temple of Yahweh, the temple of Yahweh.”
The repetition matters. It was almost like a chant or slogan. A public assurance. A phrase people could say when they did not want to examine themselves too closely.
They had a sacred place, so they assumed they had divine protection.
But Jeremiah exposed the lie beneath the slogan. The people thought God’s name could be invoked without God’s ways being obeyed. They thought religious identity could replace righteousness. They thought the temple could protect them from judgment while they continued in injustice.
That is one of the oldest temptations of religious people.
We can mistake proximity to holy things for holiness. We can confuse Christian language with true obedience to Christ. We can assume that because we mention God, defend God, vote for God, build for God, sing to God, or claim God, we are actually submitted to God.
Jeremiah says otherwise.
The Lord was not impressed by temple language when the people were oppressing the foreigner, the fatherless, and the widow. He was not impressed by public worship while their hands were stained with violence. He was not impressed by national confidence when their hearts were far from Him.
God would not be used.
When the Nation Becomes the Temple
Christian nationalism becomes spiritually dangerous when the nation starts functioning like Judah’s temple.
- The country becomes the sacred object.
- The flag becomes the holy symbol.
- The political movement becomes the place of belonging.
- The leader becomes the defender of God’s people.
- The nation’s success becomes proof of God’s favor.
- The nation’s enemies become God’s enemies.
- The language of faith becomes a tool for power.
This does not always happen all at once. It often happens slowly. A legitimate love of country becomes a belief that the country is uniquely righteous. A concern for moral decline becomes permission to treat political opponents as enemies to be crushed. A desire for religious freedom becomes a demand for religious privilege. A defense of Christian values becomes a refusal to repent when Christians themselves act unjustly.
That is how sacred language becomes a shield.
In recent years, researchers have tried to measure how widespread Christian nationalist views are in the United States. PRRI’s 2024 American Values Atlas estimated that about 10 percent of Americans qualified as Christian nationalism adherents and 20 percent as sympathizers, based on a set of questions about Christianity, American identity, and the role of the U.S. government.
Pew Research Center also found in April 2026 that public familiarity with the term has grown, with 59 percent of U.S. adults saying they had heard or read at least a little about Christian nationalism, up from 45 percent in 2024. Pew also found that 10 percent of U.S. adults had a favorable view of Christian nationalism, while 31 percent had an unfavorable view.
Those numbers matter, but they are not the deepest issue. The deeper issue is spiritual. Whenever Christians begin to treat national power as the guardian of the gospel, they have already misunderstood the gospel.
The church does not need the state to make Christ Lord. He already is.
The Danger of Sacred Cover
Jeremiah’s warning was not simply that Judah sinned. The warning was that Judah sinned while claiming religious security.
That is the danger of sacred cover.
Sacred cover is what happens when people use the name of God to avoid accountability before God. It happens when Christian identity becomes a way to deflect criticism instead of receiving correction. It happens when people say, “We are God’s people,” while ignoring what God has actually commanded.
Jeremiah 7 is painfully specific. The people were stealing, murdering, committing adultery, swearing falsely, worshiping other gods, and then entering the temple as though worship canceled out rebellion.
The modern version may look different, but the pattern is familiar.
People can speak of God while spreading lies.
People can defend Christianity while despising immigrants, strangers, or the poor.
People can talk about righteousness while excusing corruption.
People can condemn immorality in their enemies while protecting it among their allies.
People can quote Scripture while ignoring justice, mercy, humility, and faithfulness.
People can use religious language to baptize anger, greed, fear, vengeance, and pride.
This is not Christianity. It is the old temple lie wearing modern clothes.
The Lord calls His people not only to bear His name, but to reflect His character.
America Is Not Judah
There is an important difference we must not ignore.
America is not ancient Judah. The United States is not covenant Israel. Washington is not Jerusalem. The White House is not the temple. The Constitution is not Scripture. No earthly nation today holds the same covenant role Israel held in the biblical story.
That distinction matters because Christian nationalism often blurs categories God Himself has not blurred.
In the Old Testament, Israel was uniquely called as God’s covenant people under the law given through Moses. In the New Testament, the people of God are not defined by one earthly nation, ethnicity, language, or government. The church is a redeemed people from every tribe, tongue, people, and nation. Our citizenship is in heaven (Philippians 3:20). Our King is Christ. Our unity is not found in a flag, but in the blood of the Lamb.
This does not mean nations are meaningless. God rules over them. He judges them. He raises up leaders and brings them down. He cares about justice in public life. But no modern nation can claim immunity from judgment because it uses Christian language.
Jeremiah would not let Judah hide behind the temple.
We should not let America hide behind Christianity.
When Repentance Is Replaced by Branding
One of the great dangers of public Christianity is that it can become a brand.
A politician can invoke God.
A movement can use Bible verses.
A party can court church leaders.
A public figure can pose with Christian symbols.
A nation can claim religious heritage.
A crowd can chant spiritual language.
But branding is not repentance.
Jeremiah was not sent to improve Judah’s religious messaging. He was sent to call the people back to covenant faithfulness. The problem was not that Judah needed a better slogan. The problem was that Judah needed a clean heart, changed conduct, and truthful worship.
The same is true today.
The church does not need more powerful religious branding. It needs holiness. It needs truth. It needs courage. It needs repentance. It needs to recover the difference between defending Christianity as a cultural identity and following Jesus as Lord.
Christian nationalism is so tempting because it offers a shortcut. It promises belonging without discipleship. It offers power without the cross. It allows people to feel like defenders of God while avoiding the slower, humbler work of becoming like Christ.
But Jesus never told His disciples to conquer the nations through domination. He told them to make disciples, bear witness, love enemies, carry the cross, and proclaim the kingdom of God.
The kingdom of God does not need to be protected by lies. It is not advanced by cruelty. It is not purified by hatred. It is not made holy by political victory.
The Prophetic Question for Today
Jeremiah forces us to ask uncomfortable questions.
Are we trusting God, or are we trusting religious identity?
Are we following Jesus, or are we using Jesus to defend our tribe?
Are we seeking righteousness, or are we seeking power with a Bible verse attached?
Are we willing to repent when our side sins, or do we only condemn the sins of our enemies?
Are we protecting the vulnerable, or only protecting our influence?
Are we honoring Christ, or are we asking Christ to honor our nation, our movement, our fear, and our pride?
These questions are not attacks on the church. They are acts of mercy. The prophets always sound harsh to people who want comfort without correction, but their warnings are gifts. They tell the truth before judgment arrives.
Jeremiah was not anti-temple. He was anti-deception. He was not against worship. He was against worship that covered rebellion. He was not against Judah because he hated Judah. He warned Judah because God was calling His people to repent.
The church today needs that same mercy.
The Name Christian Is Not a Cover
The name “Christian” is precious because it belongs to Christ. It should not be used as camouflage for sin.
To call ourselves Christian is to identify with the crucified and risen Lord. It is to belong to the One who humbled Himself, washed feet, welcomed sinners, confronted hypocrites, told the truth, carried the cross, and defeated evil not by becoming evil, but by overcoming it through faithful obedience.
That name should make us tremble before we attach it to our ambitions.
If Christianity becomes a banner under which we excuse pride, cruelty, dishonesty, greed, racism, corruption, or violence, then we are not defending the faith. We are taking the Lord’s name in vain.
That may be the deepest connection between Jeremiah’s temple sermon and today’s Christian nationalism.
Judah thought the temple could cover disobedience.
Modern Christians may be tempted to think public Christianity can do the same.
But God is not manipulated by symbols. He is not impressed by slogans. He does not need national flattery. He does not confuse religious noise with faithful obedience.
The Lord still asks for truth in the inward parts. He still calls His people to justice, mercy, humility, and faithfulness. He still judges empty religion. He still refuses to let His name become a shield for sin.
The Way Back
The answer is not for Christians to stop caring about public life. The answer is for Christians to care about public life as Christians.
That means we tell the truth even when it costs our side.
We reject lies even when they help our cause.
We defend the dignity of people made in God’s image.
We refuse to confuse any political leader with a savior.
We remember that the church is not the servant of the state.
We submit every earthly loyalty to the lordship of Christ.
Most of all, we repent.
Jeremiah’s sermon at the temple gate was not merely a prediction of doom. It was a call to return. God was exposing the lie so His people could stop trusting it. He was tearing away false confidence so they could seek true mercy.
That is still the grace inside the warning.
Christian nationalism offers the comfort of sacred cover. Jeremiah offers the mercy of holy exposure. One lets us hide behind the temple. The other calls us to stand before God without pretending.
The church must choose which voice it will hear.
Because the Lord does not call His people merely to claim His name before the world. He calls us to bear His name faithfully.
And if Jeremiah teaches us anything, it is this: no temple, no nation, no slogan, no leader, no movement, and no religious identity can protect people who refuse the God they claim to honor.
