Magnum principium
Magnum principium ("The Great Principle") is an apostolic letter issued by Pope Francis motu proprio ("on his own authority") and dated 3 September 2017. It modified the 1983 Code of Canon Law to shift responsibility and authority for translations of liturgical texts into modern languages to national and regional conferences of bishops and restrict the role of the Congregation for Divine Worship and the Discipline of the Sacraments (CDW).
