24. The Crusades and the Inquisition - For the General Audience (2 of 2)

He distinguished His kingdom from every earthly kingdom by precisely the criterion Christian nationalism fails: His servants do not fight to establish it by political force.

On the road to Jerusalem, James and John asked to sit at His right and left hand in His kingdom - the political cabinet positions in the restored Davidic monarchy. He told them they did not know what they were asking, and that greatness in His kingdom was defined by service rather than power (Mark 10:35-45).

After the resurrection, the disciples asked: "Lord, are you at this time going to restore the kingdom to Israel?" (Acts 1:6). The question was the nationalist question - finally, now, after the resurrection, will the political program commence? He redirected them entirely: "It is not for you to know the times or dates the Father has set by his own authority. But you will receive power when the Holy Spirit comes on you; and you will be my witnesses..." (Acts 1:7-8). Not political power. Witness.

At every point where the political messianic project was offered, Jesus declined it. The Christian nationalist project is offering Him the crowd's invitation from John 6. He already answered that question.

The Tertullian Warning - Applied

The Tertullian warning runs directly through this: once you are motivated to defend a position rather than test it, your critical faculties - however formidable - are working for the wrong team.

Christian nationalism is Tertullian's error at political scale. The sincere believer who becomes convinced that their national-political vision is God's will has reached the point where the position is no longer being tested but defended. The theological questions - does Jesus actually authorize this project? does the New Testament describe the church's mission in these terms? - are no longer being asked. The political identity has become the framework inside which the faith is interpreted, rather than the faith being the framework inside which the political identity is examined.

The result is predictable and has been produced before. The German church under National Socialism was populated by sincere Christians who convinced themselves that the national renewal project was God's project. The medieval church's political power produced the Inquisition. The Constantinian settlement - Christianity as the official religion of the Roman Empire - produced centuries of coerced belief and institutionalized violence that the pre-Constantinian church, which had no political power and enormous spiritual vitality, never produced.

Power, acquired by the church as an institution, has a consistent historical record. It does not make the church more faithful. It makes it more like whatever power structure it has attached itself to.

The Distinction the Disciple Must Hold

Christian political engagement is not the error. It is appropriate and sometimes necessary. Christians bringing their values to bear on questions of justice, poverty, the sanctity of life, the dignity of every person made in the image of God - this is salt and light functioning in the political sphere. Wilberforce spent forty years fighting the slave trade from inside the British Parliament. The Civil Rights movement was led by pastors who understood that the Gospel had direct political implications for a nation that was denying the image of God in Black Americans. Bonhoeffer died because he concluded that political silence in the face of genuine evil was not faithfulness but cowardice.

These are not examples of Christian nationalism. They are examples of Christians bringing specifically Christian convictions into the political sphere in ways that were accountable to the teaching of Jesus and the witness of the New Testament.

The distinction is accountability. Christian political engagement asks: does this position follow from the teaching of Jesus and the witness of Scripture? Christian nationalism asks: does this position advance the national-political project that God has blessed?

The first question produces the possibility of prophetic challenge to any political movement, including one the Christian supports. The second question produces the impossibility of prophetic challenge - because the political movement has been identified with God's purposes, and challenging it is challenging God.

The church that cannot challenge the political movement it has attached itself to has lost the prophetic voice that is its specific contribution to political life. It has become a chaplain to power rather than a witness to the Kingdom that stands in judgment over all earthly power.

⚠ Stumbling Block: "Christians who were sure God had chosen their candidate spent four years claiming every political development confirmed their theology. When events contradicted the claim, the theology adjusted to fit. That is not faith. That is motivated reasoning dressed in religious language."

✔ The Better Way: This observation is accurate and deserves acknowledgment rather than defense. The history of Christians claiming divine endorsement for political outcomes that did not materialize - or claiming that God reversed an election, or that a specific leader was a modern Cyrus, or that opposing the movement was opposing God - is a history of the theological error the Adversary described: certainty deployed in the service of a position rather than in the service of truth. The appropriate response is not to defend the claims but to say: you are right that those claims were not warranted by Scripture, that they damaged the church's credibility, and that they confused the Kingdom of God with a political project that Jesus specifically declined. The question worth asking is whether the error discredits Jesus - who never made any of those claims - or the people who made them in His name.

What Salt and Light Look Like in the Political Sphere

Salt does not announce which political party it supports. It preserves what it touches by being present in it, not by conquering it. The Christian who is genuinely salt in political life is the one whose presence makes the political conversation more honest, more just, and more attentive to the dignity of every person - regardless of which party that benefits in a given moment.

Light does not align itself with power. It shines. The Christian who is genuinely light in political life is the one whose convictions are accountable to the teaching of Jesus rather than to the interests of any political coalition - which means they will sometimes agree with their coalition and sometimes challenge it, and the challenge will be the more important witness.

The church that can only affirm the political movement it has attached itself to has no light to offer that movement. The church that maintains its prophetic independence - that can say to any political coalition, on any day, "this is where you are right and this is where you have departed from the justice God requires" - is the church that is functioning as salt and light rather than as a political asset.

"But above all pursue his kingdom and righteousness, and all these things will be given to you as well."
-- Matthew 6:33 (NET)

His kingdom. First. Before the national project. Before the political platform. Before the flag. His kingdom, which is not of this world, which does not advance by the strategies of this world, and which will outlast every earthly political arrangement that has ever claimed its endorsement.

★ Disciple Tip: The disciple engaging the Christian nationalism objection must be genuinely independent of the political identification that produced it. If the disciple's response sounds like a defense of a political movement rather than an honest application of the teaching of Jesus, the conversation is over before it begins. The person asking the question is watching to see whether the disciple's loyalty is to Jesus or to the movement. Jesus answered that question clearly from His own life. The disciple must answer it the same way.
