Many of the believers to whom Peter addressed his letters, were living in the midst of heathen, and much depended on their remaining true to the high calling of their profession. The apostle urged upon them their privileges as followers of Christ Jesus. "Ye are a chosen generation," he wrote, "a royal priesthood, an holy nation, a peculiar people; that ye should show forth the praises of Him who hath called you out of darkness into His marvelous light: which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy. 522

Mange af de troende, til hvem Peter skrev sine breve, levede blandt hedninger og det var af største betydning, at de forblev tro mod deres stillings høje kald. Apostlen påmindede dem om deres forrettigheder som Kristi Jesu disciple. "I er en udvalgt slægt," skrev han, "et kongeligt præsteskab, et helligt folk, et ejendomsfolk, for at I skal forkynde hans guddomskraft, som kaldte jer fra mørket til sit underfulde lys, I, som før ikke var et folk, men nu er Guds folk, I, som ikke fandt barmhjertighed, men nu har fundet barmhjertighed."
