Christian Mystery›SECTION TWO THE SEVEN SACRAMENTS OF THE CHURCH›CHAPTER ONE THE SACRAMENTS OF CHRISTIAN INITIATION›VII. The Grace of Baptism
The baptized have become "living stones" to be "built into a spiritual house, to be a holy priesthood." By Baptism they share in the priesthood of Christ, in his prophetic and royal mission. They are "a chosen race, a royal priesthood, a holy nation, God's own people, that [they] may declare the wonderful deeds of him who called [them] out of darkness into his marvelous light." Baptism gives a share in the common priesthood of all believers.
