Within 2 Peter itself there is strong evidence for authorship by the apostle Peter. In 2 Peter 1:1 the author claims to be “Simeon Peter . . . apostle of Jesus Christ.” Moreover, he claims to have been an eyewitness of the transfiguration (2 Pet. 1:16–18; cf. Matt. 17:1–8), an event where Peter is featured prominently in the Gospel accounts. If someone other than Peter wrote the letter under his name, as some scholars have claimed, it would be a case of deliberate deception, especially given the author’s claims to have witnessed the transfiguration. But there is no historical evidence in support of such a theory. Furthermore, writing in another person’s name was condemned among early Christians (cf. 2 Thess. 2:2; 3:17; see Introduction to 1 Timothy course: Author & Date).
Some have suggested that the literary style of 2 Peter, which differs from that of 1 Peter, indicates an author other than Peter. But Peter may have used a secretary to help write this second letter, which would not affect the genuineness of his authorship if he ultimately approved what was written.
Scholars have also questioned Petrine authorship of 2 Peter because of the similarities between chapter 2 of this letter and the book of Jude. But this is not a problem for apostolic authorship, since Peter may have included in his letter elements from Jude that he thought would be helpful for his readers. It also could have worked the other way, with Jude using Peter’s letter as his source. The parallels are close but almost never exact, so it is difficult to sort out the relationship between 2 Peter and Jude with any degree of certainty.
It is reasonable in light of all the evidence, and clearly supported by the claims of the letter itself, to conclude that the apostle Peter wrote 2 Peter.
