Most scholars think that 2 Peter was not written by the same author as 1 Peter. There are similarities between “Jude” and 2 Peter 2, but there is debate about which letter was written first.
2 Peter is written as a last testament, and thus is designed to preserve the teaching of the apostle- particularly against false teaching. The letter also contains apologetic sections which defend the teaching/testament sections. Often in Jewish writing a “testament” was a fictional genre. Most scholars also believe that 2 Peter is pseudonymous. Remember the pseudonymous writing was not considered deceptive but was an accepted literary style. It was a way of honoring the “author” or reminding the audience of the “author’s” message.
2 Peter was probably written for a general audience, rather than a particular community. 2 Peter may have been written in the late first century or early second century. Being written at that time, 2 Peter reflects two problems of the early church; a transition from primarily a Jewish culture to a Hellenistic culture and the transition from the apostolic times to the post apostolic age.
