The Church has a hierarchy as we see in the NT (bishops are overseers) and through the bishops who were apostles and disciples of Jesus we have apostolic succession. It is to these people that authority to interpret the scripture was given, because they were told how to interpret the “Word of God” by Jesus himself (this is Sacred Tradition of which you refuse to believe in), that is why Jesus says to the apostles, paraphrasing here, “whoever listens to you listens to me”.
p.s. Paul was speaking of the “One, Holy, Catholic, Apostolic” church, i.e., the Catholic Church.

God is the one who gives the ability to see and articulate His truth as revealed in Scripture via the Spirit, which leads one to the correct understanding of Scripture. Before I was a Christian I would read God’s word and a few things I understood; but most I did not although I thought I did. I’ll give you an example because I see this error all the time.
1 Corinthians 2:12-16 " Now we have received, not the spirit of the world, but the Spirit who is from God, so that we may know the things freely given to us by God, which things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual {thoughts} with spiritual {words.} But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised. But he who is spiritual appraises all things, yet he himself is appraised by no one. For WHO HAS KNOWN THE MIND OF THE LORD, THAT HE WILL INSTRUCT HIM? But we have the mind of Christ."
1 John 2:27 “the anointing which you have received from Him abides in you, and you do not need that anyone teach you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him.” Who in the Trinity is John referring to? Meditate on the answer.
“1 Corinthians 2 :Yet we do speak wisdom among those who are mature; a wisdom, however, not of this age nor of the rulers of this age, who are passing away; but we speak God’s wisdom in a mystery, the hidden {wisdom} which God predestined before the ages to our glory;…For to us God revealed {them} through the Spirit; for the Spirit searches all things, even the depths of God…Now we have received, not the spirit of the world, but the Spirit who is from God, so that we may know the things freely given to us by God, which things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual {thoughts} with spiritual {words.} But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised…But we have the mind of Christ.”
John 14 "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things,
John 15 “When the Helper comes, whom I will send to you from the Father, {that is} the Spirit of truth who proceeds from the Father, He will testify about Me.”
John 16 "But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I go, I will send Him to you. “And He, when He comes, will convict the world concerning sin and righteousness and judgment…”
I do not want to overwhelm you because Scripture has a lot more to say about the work of the Holy Spirit, which is a believers resident Truth teacher. He uses diligent study of the Scripture to lead, such as the Bereans. He uses faithful pastors and teachers who hold firm to the Truth of Scripture. He uses books and a host of other methods to enlighten the believer, which increases their wisdom, understanding and love for the Trinity.
Do you believe this is what Scripture teaches here; that it is the work of the Holy Spirit is wrought to each individual, not the Magisterium? Do you see any difference between what you believe to be true and what Scripture say is true…do you believe God?**
