Heresy isn't preaching falsehood, it's elevating one part of the truth to being the whole truth. In John 16, Christ is promising the Holy Spirit to guide the Church and teach Her. It is this Spirit which animated the Church to declare new doctrine in Acts 15 and to write the Epistles for conformity of faith.
You have taken a part of Scripture written for the Church collectively and applied it to every individual believer. Yet Scripture is clear Who has teaching authority...
1 Tim 3:15 but if I tarry long, that thou mayest know how men ought to behave themselves in the house of God, which is the church of the living God, the pillar and ground of the truth.The Bible doesn't point to Scripture as the final authority on truth. Scripture points to the Church.
2 Peter 1:20 knowing this first, that no prophecy of scripture is of private interpretation.
This seems an awfully strange thing to say if we are to read and understand the Scripture individually. Of course, history teaches the wisdom of this. As the false doctrine of Sola Scriptura has promulgated, factions have beget factions.
2 Peter 3:16 as also in all his epistles, speaking in them of these things; wherein are some things hard to be understood, which the ignorant and unstedfast wrest, as they do also the other scriptures, unto their own destruction.It isn't just hard to understand, wresting with Scripture arrogantly can lead to destruction. So many of the Protestant persuasion would say there can't possibly be any harm in reading Scripture alone. Scripture Itself bears a warning. If every believer is an authority on Scripture because of the indwelling of the Holy Spirit, then the Spirit can't hold a coherent thought. How can we possibly profess one Spirit in one Faith when we fractalize the Church through private interpretation. To paraphrase "The Incredibles"... if everyone's in charge, then no one is.

Yet, all you’re doing is asking us to accept a slave-master, rather than to serve God. Heed the words of Cyril of Jerusalem instead:
“Have thou ever in your mind this seal, which for the present has been lightly touched in my discourse, by way of summary, but shall be stated, should the Lord permit, to the best of my power with the proof from the Scriptures. For concerning the divine and holy mysteries of the Faith, not even a casual statement must be delivered without the Holy Scriptures; nor must we be drawn aside by mere plausibility and artifices of speech. Even to me, who tell you these things, give not absolute credence, unless thou receive the proof of the things which I announce from the Divine Scriptures. For this salvation which we believe depends not on ingenious reasoning , but on demonstration of the Holy Scriptures.” (Cyril of Jerusalem, Cat. Lecture 4, Ch. 17)
“2 Peter 1:20 knowing this first, that no prophecy of scripture is of private interpretation.”
PLEASE read the context. It does not say believers should not interpret Scripture. It says - in context- that all prophecy came from God and not from some private interpretation.
