Petrusbrief
The author of the First Epistle of Peter identifies himself in the opening verse as "Peter, an apostle of Jesus", and the view that the epistle was written by St. Peter is attested to by a number of Church Fathers: Irenaeus (140–203), Tertullian (150–222), Clement of Alexandria (155–215) and Origen of Alexandria (185–253). If Polycarp, who was martyred in 156, and Papias alluded to this letter, then it must have been written before the mid-2nd century. However, the Muratorian Canon of "c." 170 did not contain this, and a number of other General epistles, suggesting they were not yet being read in the Western churches. Unlike The Second Epistle of Peter, the authorship of which was debated in antiquity (see also Antilegomena), there was little debate about Peter's authorship of The First Epistle of Peter until the advent of biblical criticism in the 18th century. Assuming the letter is authentic and written by Peter, who was martyred "c." 64, the date of this epistle is probably between 60 and 64.
