Celebration of the Christian Mystery
From: Catechism of the Catholic Church
For the purpose of assisting the work of the common priesthood of the faithful, other particular ministries also exist, not consecrated by the sacrament of Holy Orders; their functions are determined by the bishops, in accord with liturgical traditions and pastoral needs. "Servers, readers, commentators, and members of the choir also exercise a genuine liturgical function."14
In the celebration of the sacraments it is thus the whole assembly that is leitourgos, each according to his function, but in the "unity of the Spirit" who acts in all. "In liturgical celebrations each person, minister or layman, who has an office to perform, should carry out all and only those parts which pertain to his office by the nature of the rite and the norms of the liturgy." (1143-1144)
