Sacraments › … › II. The Sacrament of Holy Orders in the Economy of Salvation
Two participations in the one priesthood of Christ
Christ, high priest and unique mediator, has made of the Church "a kingdom, priests for his God and Father." The whole community of believers is, as such, priestly. The faithful exercise their baptismal priesthood through their participation, each according to his own vocation, in Christ's mission as priest, prophet, and king. Through the sacraments of Baptism and Confirmation the faithful are "consecrated to be . . . A holy priesthood."
