This Apocalypse of Peter tells that the early Christians understood that a series of false christs would be followed by a final antichrist, but "this deceiver is not the Christ."

     His words "this is the deceiver who must come into the world" suggests that he is quoting John's prophecy  from memory, "For many deceivers have gone out into the world who do not confess Jesus Christ is come in the flesh. This is a deceiver and an antichrist" 2 John 7.
