This episode initially addresses the question based on Christ's interaction with Pilate in John 18:36 and John 19:11. Based on the other worldly nature of His kingdom, Christ told Pilate that his disciples didn't need to fight to protect Him. His kingdom would advance, and worldly "encouragement" or opposition is simply not a factor. Even though Christ acknowledged Pilate's DELEGATED authority in John 19:11, He doesn't make His kingdom "dependent" on Pilate's benevolent or adverse participation. Christ is crucified because He chose to lay His life down, and the kingdom of Christ is not beholden to Pilate, and by extension ANY KINGDOM of this world. The late John McArthur concluded the same, even claiming that "Christian nationalism doesn't exist." The episode concludes with a brief analysis of Matthew 28:18-19, whereby Christians are called to respond to the universal authority of Christ by making disciples from all the nations. Christ's dealings with Pilate and His subsequent instructions in the Great Commission reveal how believers are to interact with nation-states as we make individual disciples for Christ.
The Dynamic of Politics and Power in the Carnal Christian
This episode highlights potential abuse of power by carnal Christians in government. Sanctified believers identify substantially with Christian values and motivations, and the wisdom that characterizes their decisions is pure, gentle, reasonable, and without hypocrisy. (James 3:13-18) On the flip side, James warns believers that "strife and selfish ambition" are the fruits of earthly, natural, and demonic wisdom. Paul calls Corinthian believers "mere men" because their carnality was evident in strife and jealousy. (1 Corinthians 3:3) Taken together these Scriptures are a sobering reminder that Christians can operate according to a demonic agenda when they engage worldly and carnal values. Coupled together with the corrupting allure of power, carnal Christians in government tend to operate according to wisdom that is "earthly, natural, and demonic," instead of the wisdom from above, that is "pure, gentle, reasonable, and without hypocrisy." Partisan and demonizing rhetoric from professing Christians in government underscores the prevalent carnality that is sadly justified by an appeal to Christianity. A so-called "Christian state" would only exacerbate the present hypocrisy.
Clash of the Kingdoms
This episode mostly contrasts the essential characteristics of the kingdom of darkness and those of the kingdom of Christ, pointing to inevitable conflict in a so-called "Christian state." All men are naturally born into the kingdom of darkness, driven by "the big three," "the lusts of the flesh, the lust of the eyes, and the boastful pride of life." (1 John 2:16) Once a person becomes a Christian, he/she progressively identifies more with the Kingdom "big three": "righteousness, peace, and joy in the Holy Spirit." (Romans 14:17) Unfortunately many believers in the U.S. are at best "carnal Christians," in which worldly identity markers largely predominate over Kingdom characteristics. The episode then posits a grossly optimistic scenario in which 51% of American believes are substantially sanctified, motivated and identifying with the kingdom of Christ. Specifically Christian laws generated by a "Christian state" would inevitably produce a clash of the kingdoms, where the Big 3 of each would naturally collide in the public sphere. The ostensible solution, enshrined in the establishment clause of the Constitution, prohibits Congress from setting up a national church-state establishment presiding over all.
An Easy Answer, The World and Christians Want Different Things
This episode contrasts the essential characteristics of the kingdom of darkness with the kingdom of Christ, concluding that Christian nationalism is untenable. Those who make up the kingdom of darkness are dominated by the big 3, "the lusts of the flesh, the lusts of the eyes, and the boastful pride of life." (1 John 2:16) The characteristics of those participating in the kingdom of God are "righteousness, peace, and joy in the Holy Spirit." (Romans 14:17) Presuming that Christians were in the majority (51%) and all advanced in sanctification (an absurdly optimistic assessment), how would a "Christian state" govern where the remaining 49% are still dominated and controlled by the flesh? Specifically Christian laws would be untenable. Interestingly, Peter did not call Christians who now made up a "holy nation" to make secular nations Christian. He virtually acknowledges that true Christians will always be in the minority, describing them as "aliens" coming from respective countries (1 Peter 1:1, 1 Peter 2:10-11). Their obligation is rather to abstain from fleshly lusts, the defining characteristics of those still in the kingdom of darkness. Is it possible that many who obsess over culture wars and making America a Christian nation are vicariously participating in a version of the "boastful pride of life," in which a Christian state rules over its secular enemies? Rule by compulsion through a Christian nation-state becomes a power grab more aimed at punishing secularists than at persuading people to be reconciled to Christ. And Christian nationalists shouldn't be surprised that their "enemies" in the culture war reject Christ, as they push their "boastful pride of life" agenda.
