you have said enough in your posts to make it plain that you are a fan of youtube conspiracy theories with regards to scripture
first off, THERE IS NO PRIVATE INTERPRETATION of scripture:
20 Knowing this first, that no prophecy of the scripture is of any private interpretation. 2 Peter 1:20
reading II Peter 1:20 in context, we see Peter is referring to OT prophecy and the fact that God spoke through the prophets by His Holy Spirit...continuing in II Peter 2, Peter speaks about false teachers of the then present day...the time he lived in...and continuing in that chapter we read that thes false teachers reveal themselves by how they live and the sin(s) they commit
your interpretation of I John 2: 26-27 is a fallacy believed in by those who do not think they need to be taught and whose 'understanding' of scripture deviates from what is commonly understood, meaning to take the WHOLE counsel of scripture and not just a section or a few verses out of context and derive a new doctrine which actually amounts to
private interpretation
so, what is the view held on I John 2:26-27 that has been held since the conception of the NT church regarding private interpretation?
26 I am writing these things to you about those who are trying to lead you astray. 27 As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him.
1 John 2:26-27
as you are fixed on the highlighted portion above, let's look at what the intention of John actually is here
first of all, John is not speaking to isolated people who do not come together as a body of believers. John is speaking to people who DO come together as a body of believers so he is NOT writing to individuals who believe they have no teachers and can function all alone (which is actually contrary to what scripture says we are to do)
what does he mean by you do not need anyone to teach you? what does he mean about a real and not counterfeit anointing?
he is speaking of what they have been taught from the beginning...he is writing of the truth that they ALREADY so therefore they are not to accept any other teaching
you interpret it to mean they don't need a teacher
if no teacher is needed, then why is one of the gifts through the Spirit of God 'teaching'?
there is only ONE truth and there is only one devil and he takes that one truth and creates deceiving doctrines and false doctrines and false prophecies through 'doctrines of demons'...teaching spirits that imitate the Holy Spirit and lead gullible people into deception and AWAY from the truth
it is impossible that we do not need teachers as Christ Himself said to go and teach all nations
here is a longer explanation of the above from someone who is answering the question you asked:
Let’s walk through the text and let the context help us out here. Admittedly, it does sound strange to hear John say in 1 John 2:27: “You have no need that anyone should teach you.” It sounds strange, because he himself is at that moment doing a kind of teaching. And it sounds strange because Jesus commanded us to teach the nations all things. And it sounds strange because teaching is a spiritual gift from God which he would want us to use — and on and on. The reasons why it would sound strange are many. So let’s look, because we know that he is not stupid. He knows what he is saying. He means what he means. And we want to dig in here and let the context help us see how this is coherent.
