Muslims might argue that the New Testament contains forgeries and that the authorship of its books, like 2 Peter, is questionable.

The acceptance of 2 Peter as a canonical book implies that early Christians believed it was genuinely authored by Peter. While some scholars suggest that the Greek style of 2 Peter differs from that of 1 Peter, this does not preclude Peter from having written it, especially given his experience in the Greek-speaking world. Additionally, the content of 2 Peter addresses issues that were relevant in the first-century church, indicating its authenticity. Furthermore, while there were doubts about 2 Peter, many early Christians accepted it, which reflects the careful discernment exercised by the early Church in determining the New Testament canon. The arguments against its authorship, therefore, do not hold significant weight and can be effectively countered by historical evidence and scholarly analysis.
