If you read the text IN CONTEXT, it is simply saying that God inspired prophecy and that that prophecy ( scripture ) came from God, not from man. The text in context does not address the issue of “private interpretation” of the scriptures as you misread it.
For example, if you read the book of Daniel the message is illustrated nicely. The king had a dream and then forgot the dream. Daniel asked God to reveal to him what the dream was and what its interpretation is. God supplied that information to Daniel. The whole point being, it was God who gave the dream and its interpretation, not some man like the false wisemen.
2 Peter 1
1Simon Peter, a servant and apostle of Jesus Christ,
To those who through the righteousness of our God and Savior Jesus Christ have received a faith as precious as ours:
2Grace and peace be yours in abundance through the** knowledge **of God and of Jesus our Lord.
Making One’s Calling and Election Sure
3His divine power has given us everything we need for life and godliness through
our knowledge of him who called us by his own glory and goodness. 4Through these he has given us his very great and precious promises, so that through them you may participate in the divine nature and escape the corruption in the world caused by evil desires.
5For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; 6and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; 7and to godliness, brotherly kindness; and to brotherly kindness, love. 8For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ. 9But if anyone does not have them, he is nearsighted and blind, and has forgotten that he has been cleansed from his past sins.
10Therefore, my brothers, be all the more eager to make your calling and election sure. For if you do these things, you will never fall, 11and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.
Prophecy of Scripture
12So I will always remind you of these things, even though you know them and
are firmly established in the truth you now have. 13I think it is right to
refresh your memory as long as I live in the tent of this body, 14because I know that I will soon put it aside, as our Lord Jesus Christ has made clear to me. 15And I will make every effort to see that after my departure you will always be able to remember these things.
16We did not follow cleverly invented stories when we told you about the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty. 17For he received honor and glory from God the Father when the voice came to him from the Majestic Glory, saying, “This is my Son, whom I love; with him I am well pleased.”
18We ourselves heard this voice that came from heaven when we were with him on the sacred mountain.
19And we have the word of the prophets made more certain, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. 20Above all,
you must understand that no prophecy of Scripture came about by the prophet’s own interpretation. 21For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.
2 Peter 2
False Teachers and Their Destruction
1But there were also false prophets among the people, just as there will be
false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them—bringing swift destruction on themselves. 2Many will follow their shameful ways and will bring the way of truth into disrepute.
When we read the scriptures in context, the catholic misinterpretation of this text disappears and frankly, you push us protestants away from you when you take scripture out of context and misapply it.
