You are a chosen race, a royal priesthood. This praise was given long ago by Moses to the ancient people of God, and now the apostle Peter rightly gives it to the Gentiles, since they have come to believe in Christ who, as the cornerstone, has brought the nations together in the salvation that belonged to Israel. Peter calls them a chosen race because of their faith, to distinguish them from those who by refusing to accept the living stone have themselves been rejected. They are a royal priesthood because they are united to the body of Christ, the supreme king and true priest. As sovereign he grants them his kingdom, and as high priest he washes away their sins by the offering of his blood. Peter says they are a royal priesthood; they must always remember to hope for an everlasting kingdom and to offer to God the sacrifice of a blameless life.
