The diocesan bishop, the first steward of the mysteries of God in the particular Church entrusted to him, is the moderator, promoter and guardian of her whole liturgical life. For the bishop, endowed with the fullness of the Sacrament of Order, is the steward of the grace of the high priesthood, especially in the Eucharist which he either himself offers or causes to be offered, by which the Church continually lives and grows.
