Peter’s language of obedience and the sprinkling of Jesus Christ’s blood strongly recalls the Sinai covenant ceremony, where Israel pledges obedience and Moses sprinkles covenant blood. The later Christian greeting develops that covenant pattern around Jesus.

James and 1 Peter both address dispersed believers with Israel-shaped identity language; 1 Peter immediately joins dispersion to tested faith. The approved evidence supports the relationship at its existing confidence level without requiring a stronger quotation, fulfillment, or typology claim than the texts warrant.

The greeting’s “strangers/sojourners of the dispersion” identity returns in 2:11 when Peter again calls the believers strangers and pilgrims and turns that identity into public conduct.
