On 28 March 2001, the Holy See issued the Instruction "Liturgiam Authenticam", which included the requirement that in translations of the liturgical texts from the official Latin originals, "the original text, insofar as possible, must be translated integrally and in the most exact manner, without omissions or additions in terms of their content, and without paraphrases or glosses. Any adaptation to the characteristics or the nature of the various vernacular languages is to be sober and discreet." This was a departure from the principle of dynamic equivalence promoted in ICEL translations after the Second Vatican Council.
