6. The Composition of New Liturgical Texts in a Vernacular Language
106. Regarding the composition of new liturgical texts prepared in vernacular languages, which may perhaps be added to those translated from the Latin editiones typicae, the norms currently in force are to be observed, in particular those contained in the Instruction Varietates legitimae. An individual Conference of Bishops shall establish one or more Commissions for the preparation of texts or for the work involved in the suitable adaptation of texts. The texts are then to be sent to the Congregation for Divine Worship and the Discipline of the Sacraments for the recognitio, prior to the publication of any books intended for the celebrants or for the general use of the Christian faithful.
107. It is to be borne in mind that the composition of new texts of prayers or rubrics is not an end in itself, but must be undertaken for the purpose of meeting a particular cultural or pastoral need. For this reason it is strictly the task of the local and national liturgical Commissions, and not of the Commissions treated in nn. 92-104 above. New texts composed in a vernacular language, just as the other adaptations legitimately introduced, are to contain nothing that is inconsistent with the function, meaning, structure, style, theological content, traditional vocabulary or other important qualities of the texts found in the editiones typicae.
108. Sung texts and liturgical hymns have a particular importance and efficacy. Especially on Sunday, the "Day of the Lord", the singing of the faithful gathered for the celebration of Holy Mass, no less than the prayers, the readings and the homily, express in an authentic way the message of the Liturgy while fostering a sense of common faith and communion in charity. If they are used widely by the faithful, they should remain relatively fixed so that confusion among the people may be avoided. Within five years from the publication of this Instruction, the Conferences of Bishops, necessarily in collaboration with the national and diocesan Commissions and with other experts, shall provide for the publication of a directory or repertory of texts intended for liturgical singing. This document shall be transmitted for the necessary recognitio to the Congregation for Divine Worship and the Discipline of the Sacraments.
