1 Peter 1:16

The scriptural citation 'because it is written, Be ye holy; for I am holy' draws Leviticus 11:44-45 and 19:2 into the letter's call for 'holy living' (1:15) — applying Israel's covenant purity code to the diaspora church as the new people of God. The Levitical holiness code framed Israel's distinctiveness from surrounding Canaanite practices through both ritual and ethical regulations; 1 Peter's transfer of the same command to a Gentile church implies that the church now occupies the covenantal position formerly held by Israel (see 2:9-10). The 'because I am holy' grounding of the human holiness imperative reflects the imitatio Dei pattern at the heart of Old Testament ethics — divine character as the template and motivation for human conduct. 2 Corinthians 7:1 ('cleansing ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God') develops the same pattern with different vocabulary.
