Peter, writing with Silvanus. The polished Greek is why some think the letter was shaped by another hand.
When
About AD 62–64, before Nero's persecution, or somewhat later.
What it is
Written to scattered believers under pressure, about how to suffer without becoming bitter or dangerous.
What to watch for
He calls them exiles in the first sentence, and the whole letter follows from that one word.
But you are a chosen people, a royal priesthood, a holy nation, a people for God’s own possession, to proclaim the virtues of Him who called you out of darkness into His marvelous light.1 Peter 2:9
