Doctrine = "The body of TRUTH."
There is no "freedom", there is no "independence" apart from the Lord Jesus Christ because He alone is THE WAY and THE TRUTH and THE LIFE and He alone has the power to truly set us free:
"Jesus answered them, “Truly, truly, I say to you, everyone who commits sin is the slave of sin. “The slave does not remain in the house forever; the son does remain forever. “So if the Son makes you free, you will be free indeed.(John 8:36-38)
As for "restoring America", or "restoring independence", God's Holy Word is very clear: all of the uniting, "banding together", all of the collective "fighting for independence" in the world cannot and will not save or help us as a nation, apart from our returning to, knowing and walking with the only TRUE and living God:
"Unless the LORD builds the house, They labor in vain who build it;
Unless the LORD guards the city, The watchman keeps awake in vain." (Psalm 127:1)
The answer to our dilemma is GOD, not just any "god" but the TRUE God! Only He can save us from ourselves, our sin and from total destruction as individuals and as a nation.
The way we learn WHO that true God is and HOW we can come into a right relationship with Him is through the Bible, the Word of God = Doctrine, the body of TRUTH.
Does doctrine sometimes divide? Yes, but that is not a bad thing, it is actually something God uses in order to demonstrate who is approved by God and who is not; what is TRUE and what is FALSE, who is RIGHT and who is WRONG:
"For, in the first place, when you come together as a church, I hear that DIVISIONS exist among you; and in part I believe it.
For there MUST also be factions among you, so that those who are APPROVED MAY BECOME EVIDENT AMONG YOU. (1 Corinthians 11:18-19, Emphasis mine.)
Doctrine should divide who attends your particular church, but it should not divide men of good will who disagree on theology, but agree on political and moral practices.
