Today we hear of the council’s opinion on “radical” adaptation:
In some places and circumstances, however, an even more radical adaptation of the liturgy is needed, and this entails greater difficulties. Wherefore:
1) The competent territorial ecclesiastical authority mentioned in Art. 22, 2, must, in this matter, carefully and prudently consider which elements from the traditions and culture of individual peoples might appropriately be admitted into divine worship. Adaptations which are judged to be useful or necessary should when be submitted to the Apostolic See, by whose consent they may be introduced.
Again, the council sees the leadership and initiation taken by bishops’ conferences. Taken with care and prudence, of course.
2) To ensure that adaptations may be made with all the circumspection which they demand, the Apostolic See will grant power to this same territorial ecclesiastical authority to permit and to direct, as the case requires, the necessary preliminary experiments over a determined period of time among certain groups suited for the purpose.
3) Because liturgical laws often involve special difficulties with respect to adaptation, particularly in mission lands, (those) who are experts in these matters must be employed to formulate them.
Consulting experts is important, too.
This all seems clear and well-defined. Any thoughts?
