2022: from my notes from my seminary class:
Most scholars do not think Peter wrote 1 & 2 “Peter”
By the early 3rd or 4th century Christians were doubting Peter wrote these.
There is a reference in the letter to “Babylon” likely in reference to Rome because the first temple was destroyed by Babylonians and Rome destroyed the 2nd temple in 70 CE. That is why scholars don't think it was Peter.
Why “Peter” as the name? Because it comes with authority
Written to whom? Pontus, Lapadocia, by thinia, Galicia, Asia provinces
Pontus and Galatia were taken by Rome by force. The others through diplomacy but must multiply
Written to Christian Gentiles who now worship Israel's God. The author cites Septuagint in ways that adopt Gentiles into the people of Israel, and the history of Israel.
Themes: “Chosen” loyalty, holiness, suffering, and displacement
Babylonians displaced Israelites
2nd Peter, gentiles “displaced from the kingdom of God”
