§1. The bishops in the first place exercise the sanctifying function; they are the high priests, the principal dispensers of the mysteries of God, and the directors, promoters, and guardians of the entire liturgical life in the church entrusted to them.
§2. Presbyters also exercise this function; sharing in the priesthood of Christ and as his ministers under the authority of the bishop, they are consecrated to celebrate divine worship and to sanctify the people.
§3. Deacons have a part in the celebration of divine worship according to the norm of the prescripts of the law.
§4. The other members of the Christian faithful also have their own part in the function of sanctifying by participating actively in their own way in liturgical celebrations, especially the Eucharist. Parents share in a particular way in this function by leading a conjugal life in a Christian spirit and by seeing to the Christian education of their children.
