Peter, an apostle of Jesus Christ, to the pilgrims of the Dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, elect according to the foreknowledge of God the Father, in sanctification of the Spirit, for obedience and sprinkling of the blood of Jesus Christ: Grace to you and peace be multiplied.
The odd (odd to Gentile ears like mine, anyway) phrase "for obedience and sprinkling of the blood of Jesus Christ" is likely a reference to the sealing of the New Covenant, the Old Covenant being sealed with blood by Moses at Sinai (Exodus 24:8):
And Moses took the blood, sprinkled it on the people, and said, "This is the blood of the covenant which the LORD has made with you according to all these words."
Elected by the Father.
Sanctified by the Spirit.
Sprinkled into the Covenant by the Son.
