Other notes:

The first epistle of Peter is revered as holy by Christians.

The letter is one of five letters believed to be written by Jesus's Apostles. 

It is probable that Peter himself didn't write the letter himself but that he dictated it. 

The letter would have been written not long before Peter was killed, which according to Christian tradition was by crucifixion upside-down. The tradition dates back as far as the late first century.
