"First Peter had to help its readers justify their existence as Christians living as a 'holy community' within society. It was a single strategy with two interlocking components: creating an identity that separated them from Roman culture, and yet showing how they, as a 'community of the elect,' upheld the best of Greek and Roman values by 'living honorably among Gentiles.' First Peter does not urge its readers to reject the larger society wholesale. Instead, it urges a policy of selective accommodation. Those values that contribute to moral ruin it rejects wholeheartedly; those that foster political stability and social order it upholds steadfastly and encourages vigorously."
