God commands us to obey his words. I cannot bring to mind any passage where God tells us to correctly interpret his words. We can either obey them, pervert them, or ignore them. Many end up ignoring scripture by "interpretation" inventions.
It's not that complicated at all. All the law is summarized in loving your neighbor as yourself (Romans 13:9; John 1:5).
Those who do not want to obey the holy scriptures seek an interpretation to make the commandment void. Agreement is to be expected according to scripture:
Be of the same mind... (Romans 12:16).
Speak the same things...and that there be no divisions among you...be perfectly joined together (1 Corinthians 1:10).
There should be no schism in the body (1 Corinthians 12:25).
Be likeminded...being of one accord, of one mind (Philippians 2:2).
Walk by the same rule...mind the same thing (Philippians 3:16).
Reprove, rebuke, exhort with all longsuffering and doctrine. For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching wars; and they shall turn away their ears from the truth (2 Timothy 4:2-4).
Notice it does not say, They shall misinterpret the truth, but that they will turn away their ears from it.
There are multitudes of interpretations out there that make people turn away their ears from the holy scriptures.
As soon as someone plays the 'interpretation' and 'context' card when discussing scripture, that's a red flag for me.
I respect your views. But let me explain my reasons for seeing this the way I do: Think of Eric Liddel, who was a Christian and the movie, "Chariots of Fire" - is about how he enjoyed the sport of racing. But I know of one spiritual error of belief he had, in all sincerity - that of his belief that a Christian should rest physically on the Sabbath day. Also, I know the Charles Spurgeon, a famous evangelist of the past, used to smoke, and he didn't think it was wrong to do so. He finally came to see he shouldn't be doing it and stopped smoking. But in both of these cases, they both had errors of belief in nonessential matters, compared to salvation. I think Eric Liddel died, probably still holding to that error of belief. So he's in heaven, as his heart was right towards God. And if Charles Spurgeon had died before he came to see that he shouldn't be smoking, he'd still have gone to heaven even then. Since his heart was right towards God.
However, people who knowingly disobey any of God's laws in the scriptures that God intends for them to be obeying - are certainly headed for hell if they never repent of it in this life.
Here are some verses that show a need to be tolerant and patient with those who have errors of belief in the less important matters of the Bible:
1 Cor 8:1
8:1 Now as touching things offered unto idols, we know that we all have knowledge. Knowledge puffeth up, but charity edifieth.
KJV
Rom 14:5-6
5 One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.
6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.
KJV
1 Cor 8:7
7 Howbeit there is not in every man that knowledge: for some with conscience of the idol unto this hour eat it as a thing offered unto an idol; and their conscience being weak is defiled.
KJV
1 Cor 10:29
29 Conscience, I say, not thine own, but of the other: for why is my liberty judged of another man's conscience?
KJV
To me, it looks like there are both scriptures that are easy to understand, and the kind that is more difficult to understand. I believe the prophetic parts of the Bible are often difficult to understand as they use much symbolism. This is one reason so many Christians aren't able to agree on the meaning of all these prophetic scriptures. Even godly people in Jesus' time, hadn't been able, at first, to correctly understand the prophecies that foretold of Jesus' coming to earth in human form, as He did long ago.
The sciptures about the way of salvation, I believe - are in the category of being simple and easy to understand. Jesus said even children are able to understand correctly, that subject.
And true, Jesus' command to love God and one's neighbor, is a simple, easy to understand statement. Yet is not sufficiently comprehendible, as to how to do that, to unbelievers. The Bible says unbelilevers aren't able to sufficiently well understand the Bible. They need to have a change of heart and attitude towards God, first, in order to attain that knowledge.
1 Cor 2:14-15
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
KJV
To me, the scriptures you listed, in which ones are exhorted to be likeminded spiritually, has to mean as regards to the all important seriously important subject of the way of salvation. Since there are scriptures, as I said, that imply we are not to think people are not Christians - simply on the basis that they fail to understand all parts of the Bible correctly. The danger of Christians straying from the faith has always existed in the New Testament parts of the Bible until the present. So it is always a thing to prayerfully guard against.
