Who was the author? The Holy Spirit inspired Jesus's apostle Peter to write this second book that bears Peter's name.
What is the book? Like 1 Peter, 2 Peter is an apostolic letter to the Gentile Christians of Asia Minor.
Where was it written? This second letter was also likely written from Rome.
When was it written? The letter that is 2 Peter was written after 1 Peter (see 2 Peter 3:1), and so the dating of 2 Peter depends on the dating of 1 Peter. We can say 2 Peter was written between A.D. 65 and A.D. 68, although Peter could have written it as early as A.D. 62.
Why? Attempting to help the Christians deal with false teachers and other evildoers who have come into the church, Peter's purpose in writing is said by one commentator to be threefold: to stimulate Christian growth, to combat false teaching, and to encourage watchfulness in view of the Lord's return.
How? Much like 1 Peter, 2 Peter emphasizes Christian hope, and he writes of knowledge in service of strengthening hope and defending it from error and doubt.
