Beloved, I beg you as foreigners and pilgrims, to abstain from fleshly lusts, which war against the soul;

 In 1 Peter 2:9 Peter uses a whole series of phrases which are a summary of the functions of the Church. He calls the Christians "a chosen race, a royal priesthood, a people dedicated to God, a nation for him specially to possess." Peter is steeped in the Old Testament and these phrases are all great description of the people of Israel. They come from two main sources. In Isaiah 43:21 Isaiah hears God say, "The people whom I formed for myself." But even more in Exodus 19:5-6 the voice of God is heard: "Now, therefore, if you will obey my voice and keep my covenant, you shall be my own possession among all people; for all the earth is mine: and you shall be to me a kingdom of priests, and a holy nation." The great promises which God made to his people Israel are being fulfilled to the Church, the new Israel. Every one of these titles is full of meaning.
