By A.P, friend of DCCI.
The authorship of 2 Peter is attacked by many liberal New Testament scholars such as Bart Ehrmann. The claim is that because the Greek writing style of 1 Peter is so strikingly different to 2 Peter, they must have been written by different authors.
However there are good reasons to believe 2 Peter is still authored by Peter. It was common practice at the time to use an amaneunsis (scribe) or secretary to help with letter writing, and that Peter himself needed assistance as we see from 1 Peter 5:12:
“With the help of Silas,a] whom I regard as a faithful brother, I have written to you briefly, encouraging you and testifying that this is the true grace of God. Stand fast in it.”
So it may be the case that Silas was acting as Peter’s amanuensis in 1 Peter whereas 2 Peter was written either by Peter himself or another amanuensis. This was Jerome’s view. So stylistic differences in themselves are not a strong argument against the Petrine authorship of 2 Peter.
Another argument for 2nd Peter’s authenticity is the strong internal evidence. Peter claims authorship right at the beginning of the letter:
“Simon 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:
2 Grace and peace be yours in abundance through the knowledge of God and of Jesus our Lord.”
He also says it is his second letter to the churches:
“Dear friends, this is now my second letter to you”
It claims to come from an eye-witness of Jesus:
“For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty. 17 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.”b] 18 We ourselves heard this voice that came from heaven when we were with him on the sacred mountain.”
The author uses the same words in 2 Peter 1:17 as the transfiguration account in Matthew 17:5:
“While he was still speaking, a bright cloud covered them, and a voice from the cloud said, “This is my Son, whom I love; with him I am well pleased. Listen to him!” (Matthew 17:5)
“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.” (2 Peter 1:17)
Is the author just plagiarising Matthew? Or does the author remember the words the same way because he was actually there? Peter seems to be making that very point – unless the author is a brazen liar.
The author of 2 Peter is also fully aware of the writings of Paul and calls him “our beloved brother” (2 Peter 3:15-16). Peter and Paul knew each other personally; Galatians 1 and 2 tells us that Paul became acquainted with Peter three years after his conversion and that Peter, James and John “extended the right hand of fellowship” to Paul. The way the author writes about Paul in the present tense suggests he is still alive and they are contemporaries:
