The First Epistle of Peter is the sixtieth book in the Christian Bible, and the twenty-first in the New Testament. This book is believed to be a letter from Peter to fellow Christians. The traditional Roman Catholic belief is that was written during his time as Bishop of Rome or Bishop of Antioch but that is not said in the letter, which says that it was written from Babylon. In the Book of Revelation Babylon is used as a code word for Rome. The letter was sent to Christian churches in Asia Minor that were being persecuted for their faith.
