Pope Francis has issued a motu proprio Magnum Principium, a modification of Canon Law 838, which grants bishops’ conferences greater control over the translation of liturgical texts. This includes the power to make adaptations which the bishops deem appropriate for their regions.
Until now, Canon 838 (§1) stated that "The direction of the sacred liturgy depends solely on the authority of the Church, namely, that of the Apostolic See." Paragraph §2 said: "It is for the Apostolic See to order the liturgy of the universal Church," but now the Apostolic See has the task of "recognizing adaptations approved under the law of the Episcopal Conference." (§2) In other words, the power of the Curia is reduced from authorizing to approving texts that are generated by episcopal conferences.
