But ye are a chosen race, a royal priesthood, an holy nation, a purchased people, that ye may shew forth the virtues of him who hath called you out of darkness into his marvellous light: Who in time past were not a people, but now are the people of God;

To him that loved us, and hath washed us from our sins with his own blood, and hath made us kings and priests unto his God and Father, to him be the glory and the might for ever.
