First Peter 1.3–2.10 weaves a new familial and ethnic identity for believers through a complex series of interlocking metaphors. How does this identity influence the ethical exhortation beginning in 2.11? The current article argues that an answer is found in the Greco-Roman structures of exemplarity. First, the article identifies four explicit markers of exemplarity discourse in 1 Peter: ὑπογραμμός (2.21), the footsteps idiom (2.21), the term ἀντίτυπος (3.21) and the term τύποι (5.3). Next, it surveys how exemplarity functioned in the Greco-Roman world. Greek and Roman literature demonstrate a clear preference for domestic exempla. Similarly, as a new family and ethnic group, Christian believers require new exempla suited to their new Christian identity. In this light, 1 Peter's ethical instruction can be more deeply appreciated. Finally, this article investigates how exemplarity dynamics illuminate Jesus as exemplar par excellence in 1 Peter. First Peter depicts Jesus’ passion with language of the Isaianic suffering servant (2.22–5). Jesus’ exemplarity is given to slaves, who are implicitly held up as models for all believers. Exemplarity thus draws its strength from the past (the suffering servant, Jesus) as it challenges those in the present and future (slaves, all believers) to become like these models.
