2Pe 3:15 And account [that] the longsuffering of our Lord [is] salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you;

2Pe 3:16 As also in all [his] epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as [they do] also the other scriptures, unto their own destruction.

2Pe 3:17 Ye therefore, beloved, seeing ye know [these things] before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.

This passage seals the case for Paul being a true apostle in the minds of many Christians. Many see this passage as an implication that Peter is fully endorsing Paul as a true Apostle of the Lamb, even thought the passage does not label Paul as an apostle.   Those who see the whole of our Savior's Gospel at odds with Paul's Gospel must reconsider that traditional implication.

My worldview has lead me to the concern that we have been lied to.  The conflict between Peter and Paul in Acts is presented entirely from Paul's point of view.  Then Second Peter not only apparently endorses Paul, but it also puts Paul's words in Peter's mouth.  I see that the message of the Messiah was compromised and that Second Peter is one of the tools that accomplishes this purpose. 

Those who hold that Second Peter was written be the Apostle Peter point out how a change in punctuation can make the passage have a completely different meaning or that the effects of Second Peter were prophesied by the Messiah. 

Those who question the authorship of Second Peter have evidence that this book is probably the most likely book in the New Testament to be a psuedepigraph.  Doug Del Tondo includes further thoughts along this line of reasoning in pages 16 and 17 of this appendix from Jesus' Words Only.

Another argument is that both First and Second Peter are forgeries.  Silvanus as both the writer of First Peter (1 Peter 5:12) and a companion of Paul (2 Corinthians 1:12, 1 and 2 Thessalonians 1:1) suggest a strong Pauline influence.  In Second Peter we have, not only the apparent endorsement of Paul by Peter, but we also have Paul's message restated by Peter. 

I keep going back to not necessarily wanting to believe the official word, whether the 911 Commission Report, or the message promoting Paul in the New Testament.
