“But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:”
King James Version (KJV)
2:9 But ye - Who believe in Christ Are - In a higher sense than ever the Jews were. A chosen or elect race, a royal priesthood - Kings and priests unto God, #Rev 1:6|. As princes, ye have power with God, and victory over sin, the world, and the devil: as priests, ye are consecrated to God, for offering spiritual sacrifices. Ye Christians are as one holy nation, under Christ your King. A purchased people - Who are his peculiar property. That ye may show forth - By your whole behaviour, to all mankind. The virtues - The excellent glory, the mercy, wisdom, and power of him, Christ, who hath called you out of the darkness of ignorance, error, sin, and misery.
1Pe 2:9 But ye [are] a chosen generation. "An elect race" (Revised Version). God's chosen race, like ancient Israel. Christians are now the chosen people (Isa 43:21). A royal priesthood. See Ex 19:6. The Hebrew passage which Peter refers to means "a kingdom of priests". Either this is its meaning, or that all in it, "anointed ones" like Christ, are in some sense like him, priest-kings. An holy nation. Set apart to God. A peculiar people. "A people for [God's] own possession" (Revised Version). Differing from the world in life. That ye should shew forth. They differ from the world that their holy lives may shine as a light and honor God. Out of darkness. In this verse and 1Pe 2:10 Peter surely has in mind Gentile Christians.
