This was predicted.
And shouldn't surprise you.
This has happened in the past. Christian progressives thought they could use the power of government a hundred years ago to create a perfect government. They were also obsessed with race and racial purity like today's Christian Nationalists have been.
This led to a resurgence of the KKK, a segregated federal government, and the worst expansion of government power of all time under Woodrow Wilson, a supposed Christian. He claimed Christianity but his actions caused immense damage to the country. He had let politics and the idea of control and power overcome his view of the Gospel.
One hundred years later we have Christians obsessing over race and trying to create a Christian utopia on Earth through government power again. It was only ever going to go the way it did in the past.
Step back from the ledge. Woodrow Wilson damaged the country in ways we are still dealing with. It won't be better because it's "our side" this time. This will always be destined to fail because it is not how the Lord called us to live and to behave.
The premise itself is wrong that we need to use government power to enforce our beliefs.
If this was the way to extend the Gospel into the world, why is it not mentioned in the texts? Why doesn't Jesus ever command His followers to grab as much power as possible? Why does He instead say that they need to be HUMBLE? Why does He call us to lead by being servants? Why didn't He leave us a political manual like so many other leaders have?
Should Christians be involved in politics and government? OF COURSE! Just as we should be involved in art, academia, military, and any other role that impacts this world as much as we can be. Use your God-given talents to glorify the Kingdom.
But don't mistake Christians operating government for the growth of God's kingdom. God's Kingdom is "not of this world," and it comes through lives changed by the Gospel. He writes His laws not in congress but in the hearts of man through His Holy Spirit. He is so much greater than a gavel slapped by a judge or a glinting crown on a king. Holy Roman Empire's have come and gone, colonial christians have risen and fallen, and even Christian absolute monarchs had their day.
Yet through it all the true Gospel work has been done through His people in pulpits, in prayer rooms, and in the pews. Whether those pulpits were underground escaping persecution, or those pews were in fancy churches, His Word has been fruitful in the fields of His people.
Friedrich Engels, co-author of the Communist Manifesto, once listed the "character he most disliked". He only had one name: Spurgeon
Why? Because Spurgeon loved the poor, cared for the orphans, and preached hope to the people. The exact opposite message that those who wish to upend the world want. Socialism and Christianity do not mix.
Christians who compromise on the Gospel and make it about political power will always begin to see the government as the answer to their problem.
And they will be wrong.
