Last time I wrote about progressive Christianity and a Christian's biblical worldview. If you have not had the opportunity to read it, I recommend that you do so before you read this article since they are related.
The phrase started to come into use midway through Donald Trump’s first term when “White Nationalism” became the current thing bogeyman after the Charlottesville Protests. It was a very obvious linguistic trick, to try to insinuate that “White Nationalism” and “Christian Nationalism” are interchangeable. It is a pathetic attempt to smear as a racist anyone who believes that Jesus Christ is King over all the world including America. 
Tyler Huckabee observed the following:
This movement, known as Christian nationalism, is in the business of merging Christian and American identities, liberally mixing biblical teaching with the principles of constitutional democracy until the line between them is blurred or even erased altogether.Some of this seems benign on the surface. An American flag in the church pulpit. “In God We Trust” on the dollar. Christian politicians referring to the Second Amendment as a “God-given right.” Christians, after all, have a right to advocate for favorable laws just like anyone else. But real Christian nationalists aren’t out for anything so salubrious as equal treatment under the law, and their methods involve the marginalization of citizens who don’t see things according to a bracingly narrow definition of what it means to be both an American and a Christian — sometimes with deadly repercussions.At their most extreme, Christian Nationalists may describe themselves as “dominionists,” who believe Christians ought to have dominion over what they consider to be the seven forces — or, in their parlance, “mountains”— that shape culture: business, government, media, arts and entertainment, education, family and religion. (The Seven Mountain Mandate, 7M) As David Barton, a Christian Nationalist and one of the leaders of Project Blitz put it in a radio broadcast, “If you can have those seven areas, you can shape and control whatever takes place in nations, continents and even the world.”“Christian nationalism is not the same thing as patriotism or being patriotic,” Amanda Tyler explains. “I am a Patriot. We can be patriotic and still understand that we don’t need to minimize our religious convictions or somehow make those fit into a particular political affiliation or nationalistic affiliation.”“Whenever the state gets too cozy with Christianity, Christianity is the one that gets compromised,” Tyler says. “Our radical Christian values are not in line with the powers and principalities of this state. Jesus taught us that we are citizens of two kingdoms, an earthly kingdom ruled by our governments and God’s kingdom. We have to work out what we render to which kingdom.” 
The Great Commission means that if you are a Christian you are axiomatically a Christian Nationalist. If you say you are a Christian and you reject “Christian Nationalism,” you are just a disobedient Christian. (Wow! Quite radical! If I'm a genuine Christian I will be a Christian Nationalist. I have yet found that as a description of a Christ follower in Scripture) To be part of Christ’s Kingdom is to bring the kingdoms of this world into submission to Christ’s Kingship. (Again, Andrew is sharing is dominionism and not unbiblical doctrine) 
I don’t apologize for anything that I’ve said or any of the work we are doing to take dominion of our country and culture for the glory of God. Jesus gave us a mission: the Great Commission. 
Apparently the Great Commission to these Christian nationalists is taking over and having dominion over the seven mountains and thus the nation.
... that we are to take control of the seven main “mountains” that shape our culture—education, government, media, business, arts and entertainment, family, and religion—in order to implement the will of God throughout the nation and the world.
The United States won’t be saved just by converting more people to Christianity...The only way to save the nation is for those mountains to be seized by Christians...
If we are going to build a Christian movement it must be exclusively Christian and we can’t be afraid to say that out loud. We are all sinners saved by Grace, but if you do not repent and believe in Jesus Christ then you do not share our Biblical worldview and cannot participate in any meaningful position of authority in the movement. It’s just that simple. 
Christian Nationalism is not merely a political movement. It’s a social, cultural, and spiritual one. Christian Nationalism is not merely limited to the right wing in the United States. Our King has dominion over this entire earth. Every square inch. Christians around the world are rising up right at this very moment to claim what is rightfully His.
We are done being the footstool of the Enemy. We are done being pushovers. We are done with simply wanting to be left alone. Now we want to win. Win souls for Christ. Win elections. Win in the culture. Win in the education system. Win with our own technology. Our own media. Our own entertainment. Win for the glory of God. 
I said we are forming a Christian Nationalist movement and in order to be in any position of influence or leadership in the movement you must be a Christian (According to Andrew's definition). I said we are no longer going to answer to people who do not share our values and represent a diametrically different worldview (Sadly his worldview isn't biblical, but rather syncretistic) that only 2% of the country holds (Thankfully). We are the 70%+ super majority in this country and we are going to do everything we can to take dominion and disciple this nation for the glory of Jesus Christ our King. 
38 Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth:39 But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.40 And if any man will sue thee at the law, and take away thy coat, let him have thy cloke also.41 And whosoever shall compel thee to go a mile, go with him twain.42 Give to him that asketh thee, and from him that would borrow of thee turn not thou away.43 Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy.44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.46 For if ye love them which love you, what reward have ye? do not even the publicans the same?47 And if ye salute your brethren only, what do ye more than others? do not even the publicans so?48 Be ye therefore perfect, even as your Father which is in heaven is perfect. (Mt. 5:38-48)
11 And as they heard these things, he added and spake a parable, because he was nigh to Jerusalem, and because they thought that the kingdom of God should immediately appear.12 He said therefore, A certain nobleman went into a far country to receive for himself a kingdom, and to return.13 And he called his ten servants, and delivered them ten pounds, and said unto them, Occupy till I come.14 But his citizens hated him, and sent a message after him, saying, We will not have this man to reign over us.15 And it came to pass, that when he was returned, having received the kingdom, then he commanded these servants to be called unto him, to whom he had given the money, that he might know how much every man had gained by trading.16 Then came the first, saying, Lord, thy pound hath gained ten pounds.17 And he said unto him, Well, thou good servant: because thou hast been faithful in a very little, have thou authority over ten cities.18 And the second came, saying, Lord, thy pound hath gained five pounds.19 And he said likewise to him, Be thou also over five cities.20 And another came, saying, Lord, behold, here is thy pound, which I have kept laid up in a napkin:21 For I feared thee, because thou art an austere man: thou takest up that thou layedst not down, and reapest that thou didst not sow.22 And he saith unto him, Out of thine own mouth will I judge thee, thou wicked servant. Thou knewest that I was an austere man, taking up that I laid not down, and reaping that I did not sow:23 Wherefore then gavest not thou my money into the bank, that at my coming I might have required mine own with usury?24 And he said unto them that stood by, Take from him the pound, and give it to him that hath ten pounds.25 (And they said unto him, Lord, he hath ten pounds.)26 For I say unto you, That unto every one which hath shall be given; and from him that hath not, even that he hath shall be taken away from him.27 But those mine enemies, which would not that I should reign over them, bring hither, and slay them before me.
- The nobleman leaves to receive a kingdom and then return.
- The nobleman gave his servants money and told them to be engaged in business until he returns.
- When he returns he summons his servants to take account of what they had done with the money he had given them.
- Two of his servants made the money grow while a third servant hid it and did nothing with it.
- Pertaining to βιάζεται (suffers violence) he writes: the kingdom of God is sought with eagerness, haste, It is not carefully thought of as to its consequences which may not be pleasant, such as persecution by one's very own household (Mt. 10:36). Meaning that one presses himself in to seize the kingdom with his own energy as if the kingdom could be had as something to be grasped. We see this today as people eagerly and flippantly come forward to "accept Christ" without having experienced repentance of sin or having counted the cost of their acceptance (Mt. 16:24-28)
- Pertaining to βιασταὶ (violent) he writes: to suffer violence, but also to hurry into or press into without proper thought and repentance. A violent person, one who uses force, but also one who hurries to appropriate something that seems good without measuring the consequences of such an action. In Mt. 11:12 it refers to those who heard the preaching of John the Baptist and came to him to be baptized without truly repenting of their sins. They were rushing into the kingdom and as such they were βιαστα, those who speedily pushed their way in.
