Muslims often argue that the New Testament, including the Epistle of 2 Peter, is not authentic and has been altered over time.

The Epistle of 2 Peter presents itself as written by the apostle Peter, claiming personal experiences such as witnessing the transfiguration of Jesus. Critics argue that these claims are not credible, suggesting that the letter may be pseudepigraphic. However, the absence of close parallels in pseudepigraphic literature and the unique use of the name 'Simon Peter' lend credibility to its authenticity. Furthermore, the style and content of the letter do not conform to typical pseudonymous works, suggesting that if it were a forgery, it would not have been crafted in such a distinctive manner. The argument for its genuineness is strengthened by the acknowledgment of its unique features, which would be unlikely to be replicated by an imitator.
