So explain all the different denominations and interpretations that have lead to separation within the Church.
No.
Its just the way you asked, SO EXPLAIN rather then, "What are your thoughts on this"?
Why do I have to answer for His words in accordance with the question that came to your mind on them that never entered mine?
I'll post the verses from where you are springboarding your own questions...
2Titus 3:16
All scripture is given by inspiration of God
True?
Yes
Job 32:8
But there is a spirit in man: and
the inspiration of the Almighty giveth them understanding.
True?
Yes
All scripture is given for reproof
Proverbs 1:23
Turn you at my reproof:
behold,
I will pour out my spirit unto you,
I will make known my words unto you.
True?
Yes
I dont need to explain them. It appears as if your asking, if God is true please look at men and explain them.

What kind of question is that?
Just because 1 million people sit in under "the dominion" of any particular brand of church does not mean all those within it truly agree with that church. Catholics included (coming from a huge family of them) I know this very well. Its a delusion to think otherwise.
Why do people not agree might be a better question

Carnally minded? (all sorts of objectives in this mind) whether in the churches or outside them. And the Spriritually minded? (one accord having the same love for another)
....or the Borg mentality that appears as one but is more into mind and thought control?
Ok, seriously now... differences were allowed, off the top of my head there were allowable differences In how one man regarded a holy day or not. What he could eat according to conscience. What you believed about certain things (and kept to yourself) and having ones faith before God. Weaker and stronger brothers and sisters exist together. Those still yet carnal and those who were spiritual. Paul knowing His boundaries couldnt speak in the same mind (in wisdom) to those carnal but as a man. He even said that knowing his limitations but he could walk in love toward them (in that mind) just couldnt speak it lol
Being AS LORDS over anothers faith? That was something Paul said he was not. My faith rests on Christ alone. I dont claim to know it all nor am I interested in being one. I'm free to "prove all things" and so is everyone else (whether they know it or not).
Im where I am by the grace of God, same as you.
Trying to control anothers desire to prove a thing or is vain and pretending theres no differences "here" (as in my church "where I go") is a lie.
Theres all sorts of people, there are those who call upon the Lord with a pure heart and others who preach for profit. There are those who preach Christ (not out of goodwill) but out of strife and envy. There are those who desire to draw others after themselves, and thats their only concern (who is with us). There are those who have but a form of godliness and would trip over the power of it. These (and then some) exist.
Paul made no promises that there will never be false doctrines or teachers did he? Its sorta expected (with me) that there will be.
Maybe some are more comfortable with their religion and not really interested (or believe) they are called to laid hold of knowing God? Maybe they were told they needed to be in the right church so when they dead and buried they can "go to heaven" and have no clue eternal life is to be in them and its to know God?
I cant even pretend to know lol
I would guess men as lords seem to be a part of the problem and the "dum dums" who let their faith stand in the wisdom of men over the power of God (Christ).
We are called to know HIM (~the Lord of~ the book) not just ~the book of~ the Lord.
God is not the author of chaos,
Thats right He is not the author of confusion. Confusion is not just in "misunderstandings" its
WHERE ~
strife and
envy~
ARE and wherever THAT
is its not the wisdom from above but that which is earthly, sensual and devilish and surely not of the inspiration of God. I agree.
and why would He ever lead someone to believe false doctrines?
Who implied God would lead those who place their trust in Him to false doctrines?
From what I understand theres doctrine issues tied into the RC and EO divisions isnt there? Are you asking why would GOD lead either of them to any of these things?
Did God do that to you?
God is shown sending a lying Spirit. He is also capable of sending a power delusion that anyone would believe a lie right? Because they receive not a "love for the truth" right? God knows hearts, what God does He does in truth.
You might have to ask God I am not Him
