The Second Epistle of Peter, often referred to as Second Peter and written 2 Peter or in Roman numerals II Peter (especially in older references), is a book of the New Testament of the Bible, traditionally held to have been written by Saint Peter. Most modern scholars regard it as pseudepigraphical.
Second Peter quotes from and adapts the Epistle of Jude extensively, and addresses a threatening heresy which had arisen because the anticipated Second Coming of Christ had not yet occurred. It is the only New Testament book to treat other New Testament writings as scripture. Second Peter was one of the last letters included in the New Testament canon and is one of the texts that were in dispute before the canon was finalized.
According to the Epistle itself, it was composed by the Apostle Peter, an eyewitness to Jesus' ministry. It criticizes "false teachers" who distort the authentic, apostolic tradition, and predicts judgment for them. 2 Peter explains that God has delayed the Second Coming of Christ so that more people will have the chance to reject evil and find salvation. It calls on Christians to wait patiently for the parousia and to study scripture.
The date of composition has proven to be very difficult to determine. Commentaries and reference books have placed 2 Peter in almost every decade from AD 60 to 160. Many believe that it was written between 65-68 A.D. because Peter was martyred around 68 A.D. by Nero and also because Peter references his approaching death in 2 Peter 1:14 ("since I know that the putting off of my body will be soon, as our Lord Jesus Christ made clear to me").
Most biblical scholars have concluded Peter is not the author, considering the epistle pseudepigraphical. Reasons for this include its linguistic differences from 1 Peter, its apparent use of Jude, possible allusions to 2nd-century gnosticism, encouragement in the wake of a delayed parousia, and weak external support.
