This episode spells out the aspirations of the New Apostolic Reformation (NAR), particularly that of conquering the mountain of government. Che Ahn, a prominent leader in the NAR, declared on January 5, 2021 that "we are going to rule and reign through Donald Trump and under the Lordship of Jesus Christ." This form of dominionism seeks to mix church and state to the point of enabling Christians to rule and reign through secular princes. Much of the episode addresses the post-millennial expectations of the NAR, maintaining that Christians will establish the Kingdom of God on earth and usher in the millennium--Christ returning AFTER the millennium. Both the book of Revelation and Christ's Olivet discourse contradict this optimistic outlook.
My Kingdom is Not of this World
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.
Government, its Institution and Purpose
To properly answer a question on Christian nationalism, one needs to know the Biblical reason behind the institution of government along with its purpose. Government was instituted in Genesis 9:6 in response to the astronomical murder rate prior to the flood. Government was called to execute murderers, and Paul would later describe its purpose, "to bring wrath on the one who practices evil." (Romans 13:4) Very critically, the government that Christians were called to submit to was the Roman Empire led by Nero, and all examples of government authority instituted by God in the New Testament are secular. Nevertheless Christians are obliged to submit themselves based on universal apprehension of the moral law. Based on the moral law alone (apart from "Christian" law), secular princes execute justice, which prescribes penalties for breaking the law. Additionally, Christ Himself, facing unjust execution, nevertheless acknowledged Pilate had authority over Him because it was given ultimately by God. (John 19:11) The biblical description of government that emerges is one in which God accomplishes His purposes of restraining evil through secular governments, and this conclusion should inform the answer regarding Christian nationalism.
Christianity: the Recasting of Earthly Citizenship
The most common definition of Christian nationalism is the merging of fleshly and spiritual identities, even to the point where one's fleshly (national) citizenship is on par with that of one's heavenly citizenship. Yet this marrying of the 2 citizenships doesn't take into account the Biblical consequences of heavenly citizenship, in which all other identities (nationality, race, class, sex, etc.) become secondary and so-called obligations to those identities should be renegotiated. Paul insists that kingdom citizenship amounted to a transfer from the kingdom of darkness into kingdom of His beloved Son. (Colossians 1:13) The kingdom of darkness that we once participated in was headed by Satan who wielded his power through people dominated by "the lusts of the flesh, the lusts of the eyes, and the boastful pride of life." (1 John 2:16) The vast majority of people at any given time in history are enslaved to their lusts, so John isn't exaggerating when he contends that "the whole world lies in the power of the evil one." (1 John 5:19) The nation-state is the natural place for the exercise of power by lust-driven, demonically manipulated members of the kingdom of darkness. Since Christians have been transferred from this kingdom into Christ's kingdom, their primary identity is that of kingdom citizens and all secondary identities come under the Lordship of Christ in the process of sanctification. Our national citizenship obligations are renegotiated, rendering us "aliens" (1 Peter 1:1), who partake of Christ's otherworldly kingdom (John 18:36), and "ambassadors" to worldly members of the kingdom of darkness. (2 Corinthians 5:20) Christian nationalism therefore amounts to an insurmountable conflict of interest of 2 opposing kingdoms with completely different goals and means.
