4. On a Unified Version of the Liturgical Texts

87. It is recommended that there be a single translation of the liturgical books for each vernacular language, brought about by means of coordination among the Bishops of those regions where the same language is spoken.[66] If this proves truly impossible because of the circumstances, the individual Conferences of Bishops, after consultation with the Holy See, may decide either to adapt a previously existing translation or to prepare a new one. In either case, the recognitio of their acts is to be sought from the Congregation for Divine Worship and the Discipline of the Sacraments.

88. In the case of the Order of Mass and those parts of the Sacred Liturgy that call for the direct participation of the people, a single translation should exist in a given language,[67] unless a different provision is made in individual cases.

89. Texts which are common to several Conferences, as mentioned above in nn. 87-88, are ordinarily to be approved by each of the individual Conferences of Bishops which must use them, before the confirmation of the texts is granted by the Apostolic See.[68]

90. With due regard for Catholic traditions and for all of the principles and norms contained in this Instruction, an appropriate relationship or coordination is greatly to be desired, whenever possible, between any translations intended for common use in the various Rites of the Catholic Church, especially as regards the text of Sacred Scripture. The Bishops of the Latin Church are to foster the same in a spirit of respectful and fraternal cooperation.

91. A similar agreement is desirable also with the particular non-Catholic Eastern Churches or with the authorities of the Protestant ecclesial communities,[69] provided that it is not a question of a liturgical text pertaining to doctrinal matters still in dispute, and provided also that the Churches or ecclesial communities involved have a sufficient number of adherents and that those consulted are truly capable of functioning as representatives of the same ecclesial communities. In order completely to avoid the danger of scandal or of confusion among the Christian faithful, the Catholic Church must retain full liberty of action in such agreements, even in civil law.
