This is an interesting post - I agree there are MANY views and beliefs out there by some of the greatest Bible scholars out there (past and present).
Here's how I view it:
Paul, Mark and Barnabus divided and split up in their ministries due to disagreement in Acts:
Act 15:39 And the contention was so sharp between them, that they departed asunder one from the other: and so Barnabas took Mark, and sailed unto Cyprus;
So by this example, we see that we won't ALL agree on Everything for various reasons which can include:
physical wisdom, spiritual wisdom, physical age (maturity), spiritual age (spiritual maturity), level of faith, misunderstanding/misperception, level of discernment, lack of education in Hebrew/Greek, lack of seeking the Lord for truth, lack of study, spiritual pride, spiritual rebellion, spiritual apathy, personal sin, the Bible's lack of full clarity, language barriers... etc.
Clearly, if 2 Godly people hold opposing views on the same teaching, ONE of them (or both) will be wrong. What's important is that they have the CENTRAL doctrines correct to BE Born Again and perhaps at a later time, they'll both agree.
We can differ on minor doctrines... like
Luke 16:19-31... some people call that a parable, others call it a literal event.
Our salvation doesn't pivot on believing whether it's a parable or not...
but we CAN agree on the POINT of that story. It shows a very negative result if one isn't born again.
One thing I've learned tho, is when I discuss scripture passages w/ someone, and they have a large majority of "messed up" understandings of even plain verses, I quickly start asking them about CENTRAL/essential doctrines.
Often, I find that they ultimately reject one or more of the very doctrines that determine our salvation. Imo, MOST born again Christians do have a general unity in agreement on scripture and have a like mind.
When you constantly oppose someone else scripturally, (to me), it's a pretty good indicator that you might not be of the Same unity of Spirit (or there's something wrong or some spiritual issue)... because I truly believe God gives us a deep unity of agreement in a majority of teachings/principles.
Phl 2:2 Fulfil ye my joy, that ye be likeminded, having the same love, [being] of one accord, of one mind.
Eventually (and hopefully), we'll all grow & mature and become more knowledgable in the Lord as we go along.
I believe the KEY is to
be able to admit we don't know everything there is to know, and have a teachable spirit.
I want to always be willing to be shown by God's Word.
