13. Diocesan Bishops, according to Canon Law, are to monitor liturgical matters in order to guarantee the common good and to ensure that everything is proceeding in peace and serenity in their Dioceses(5), always in agreement with the mens of the Holy Father clearly expressed by the Motu Proprio Summorum Pontificum.(6) In cases of controversy or well-founded doubt about the celebration in the forma extraordinaria, the Pontifical Commission Ecclesia Dei will adjudicate.
a.) Every Catholic priest who is not impeded by Canon Law(7) is to be considered idoneus (“qualified”) for the celebration of the Holy Mass in the forma extraordinaria.
21. Ordinaries are asked to offer their clergy the possibility of acquiring adequate preparation for celebrations in the forma extraordinaria. This applies also to Seminaries, where future priests should be given proper formation, including study of Latin(8) and, where pastoral needs suggest it, the opportunity to learn the forma extraordinaria of the Roman Rite.
25. New saints and certain of the new prefaces can and ought to be inserted into the 1962 Missal(9), according to provisions which will be indicated subsequently.
