I am uncertain as to your response. What you suggested is the utter opposite of what I would suggest, which is to NOT turn to the teachings of man (commentaries, etc), but turn to the Lord. Anyone who turns to the Lord will turn straight to His Holy Word.
Why you would suggest that a person turn to the teachings of man instead of directly to the Bible is perplexing.
1 John 2:27 NLT - "But you have received the Holy Spirit, and he lives within you, so you don't need anyone to teach you what is true. For the Spirit teaches you everything you need to know, and what he teaches is true--it is not a lie. So just as he has taught you, remain in fellowship with Christ."
Because what you are suggesting isn't trusting the Scriptures, but trusting one's own opinions. Your mis-use and misunderstanding of 1 John 2:27 is a perfect example of why this approach fails.
Here is 1 John 2:27 in some of its essential context:
"Children, it is the last hour, and as you have heard that antichrist is coming, so now many antichrists have come. Therefore we know that it is the last hour. They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us. But you have been anointed by the Holy One, and you all have knowledge. I write to you, not because you do not know the truth, but because you know it, and because no lie is of the truth. Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. No one who denies the Son has the Father. Whoever confesses the Son has the Father also. Let what you heard from the beginning abide in you. If what you heard from the beginning abides in you, then you too will abide in the Son and in the Father. And this is the promise that he made to us—eternal life.
I write these things to you about those who are trying to deceive you. But the anointing that you received from him abides in you, and you have no need that anyone should teach you. But as his anointing teaches you about everything, and is true, and is no lie—just as it has taught you, abide in him." - 1 John 2:18-27
John is talking about heretics, he calls them antichrists; they are preaching deeply wrong things. Nevertheless, John is confident that his readers are already well-acquainted with proper teaching. "I write to you, not because you do not know the truth, but because you know it, and because no lie is of the truth." "let what you heard from the beginning abide in you. If what you heard from the beginning abides in you, then you too will abide in the Son and in the Father"
Therefore John can say "you have no need that anyone should teach you", that is they do not need to listen to these false teachers, they have already received the truth in what they have been taught from the beginning. If they keep to the teaching as they first received it, the Holy Spirit will keep them in true faith, they will not fall astray but remain steadfast in the faith.
So not only does this passage not say what you are trying to make it say, it actually says the opposite of what you want it to say.
St. John isn't saying "don't listen to good teaching from good teachers" it's saying "you have already received good teaching, hold to that, and you'll be fine"
It is, in fact, the antichrists that John mentions who, though claiming to represent the apostles, have nothing to do with them. It is those who come in their own authority, claiming their own insights, revelations, and claims of spiritual significance who we should ignore; but instead remain committed to what has been received from the beginning. As the Apostles themselves taught, right there in the plain text of Holy Scripture.
Scripture rules over us. We do not rule over Scripture.
