I don’t understand your question or comment. Sorry.
Patriotism is defined as devoted love, support, and defense of one's country; national loyalty.
Scripture says seek first the kingdom of God. It becomes very important what the kingdom is. If you define the kingdom as something which is only spiritual (not a biblical idea) then it is entirely different than if you believe Rev. 11:15 that the kingdoms of this world are become the kindom of Christ. Dan 7 says the same.
Further you use church as a building. Common, but not biblical or correct for your argument. Churches are secular. THE church is not secular.
Think about this in terms of the OT. God established a kingdom at Mt. Sinai. There were judges, military leaders, elders, there was the rule of law, with one nation under God. The people all agreed three times to their form of government, with God as head. That agreement is a constitution of sorts. That reigns under God and his laws. Was it secular? Yes. Was it Christian? Yes, in a forward looking sense.
You mention mans relationship to God and man, while rejecting the idea of secular. Kingdoms are in essence mans relationship to man, and their king. It IS secular and if it is Christian it is simultaneously spiritual.
