Can. 838

§1. The ordering and guidance of the sacred liturgy depends solely upon the authority of the Church, namely, that of the Apostolic See and, as provided by law, that of the diocesan Bishop. § 2. It is for the Apostolic See to order the sacred liturgy of the universal Church, publish liturgical books, recognise adaptations approved by the Episcopal Conference according to the norm of law, and exercise vigilance that liturgical regulations are observed faithfully everywhere. § 3. It pertains to the Episcopal Conferences to faithfully prepare versions of the liturgical books in vernacular languages, suitably accommodated within defined limits, and to approve and publish the liturgical books for the regions for which they are responsible after the confirmation of the Apostolic See. § 4 Within the limits of his competence, it belongs to the diocesan Bishop to lay down in the Church entrusted to his care, liturgical regulations which are binding on all.
