The greatest heresies have been built on the backs of those who feel that only a priviledge few can rightfully interpret the scriptures.

And the apostasy of Korah warned about by Peter was rebelling against authority by claiming all were equal.

[HarleyD]

This is what Peter wrote about the word and its authority:

2Pe 1:18 And we heard this voice being borne from Heaven, being with Him in the holy mountain.
2Pe 1:19 We also have a more sure Word of prophecy, to which you do well to take heed, as to a light that shines in a dark place, until the day dawns and the Daystar arises in your hearts,
2Pe 1:20 knowing this first, that no prophecy of the Scripture came into being of its own private interpretation.
2Pe 1:21 For prophecy was not borne at any time by the will of man, but holy men of God spoke being borne along by the Holy Spirit.

...

2Pe 3:1 Beloved, I now write this second letter to you, in which I stir up your pure mind by reminder
2Pe 3:2 to remember the words which were spoken before by the holy prophets, and of the commandment of the Lord and Savior by us, the apostles.
