16. In the case of a priest who presents himself occasionally in a parish church or an oratory with some faithful, and wishes to celebrate in the forma extraordinaria, as foreseen by articles 2 and 4 of the Motu Proprio Summorum Pontificum, the pastor or rector of the church, or the priest responsible, is to permit such a celebration, while respecting the schedule of liturgical celebrations in that same church.
17.1. In deciding individual cases, the pastor or the rector, or the priest responsible for a church, is to be guided by his own prudence, motivated by pastoral zeal and a spirit of generous welcome.
17.2. In cases of groups which are quite small, they may approach the Ordinary of the place to identify a church in which these faithful may be able to come together for such celebrations, in order to ensure easier participation and a more worthy celebration of the Holy Mass.
18. Even in sanctuaries and places of pilgrimage the possibility to celebrate in the forma extraordinaria is to be offered to groups of pilgrims who request it (cf. Motu Proprio Summorum Pontificum, art. 5 - 3), if there is a qualified priest.
19. The faithful who ask for the celebration of the forma extraordinaria must not in any way support or belong to groups which show themselves to be against the validity or legitimacy of the Holy Mass or the Sacraments celebrated in the forma ordinaria or against the Roman Pontiff as Supreme Pastor of the Universal Church.
Sacerdos idoneus ("Qualified Priest") (cf. Motu Proprio Summorum Pontificum, art 5 - 4)
20. With respect to the question of the necessary requirements for a priest to be held idoneus ("qualified") to celebrate in the forma extraordinaria, the following is hereby stated:
a. Every Catholic priest who is not impeded by Canon Law is to be considered idoneus ("qualified") for the celebration of the Holy Mass in the forma extraordinaria.
b. Regarding the use of the Latin language, a basic knowledge is necessary, allowing the priest to pronounce the words correctly and understand their meaning.
c. Regarding knowledge of the execution of the Rite, priests are presumed to be qualified who present themselves spontaneously to celebrate the forma extraordinaria, and have celebrated it previously.
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 and, where pastoral needs suggest it, the opportunity to learn the forma extraordinaria of the Roman Rite.
22. In Dioceses without qualified priests, Diocesan Bishops can request assistance from priests of the Institutes erected by the Pontifical Commission Ecclesia Dei, either to the celebrate the forma extraordinaria or to teach others how to celebrate it.
23. The faculty to celebrate sine populo (or with the participation of only one minister) in the forma extraordinaria of the Roman Rite is given by the Motu Proprio to all priests, whether secular or religious (cf. Motu Proprio Summorum Pontificum, art. 2). For such celebrations therefore, priests, by provision of the Motu Proprio Summorum Pontificum, do not require any special permission from their Ordinaries or superiors.
Liturgical and Ecclesiastical Discipline
24. The liturgical books of the forma extraordinaria are to be used as they are. All those who wish to celebrate according to the forma extraordinaria of the Roman Rite must know the pertinent rubrics and are obliged to follow them correctly.
25. New saints and certain of the new prefaces can and ought to be inserted into the 1962 Missal, according to provisions which will be indicated subsequently.
26. As foreseen by article 6 of the Motu Proprio Summorum Pontificum, the readings of the Holy Mass of the Missal of 1962 can be proclaimed either solely in the Latin language, or in Latin followed by the vernacular or, in Low Masses, solely in the vernacular.
27. With regard to the disciplinary norms connected to celebration, the ecclesiastical discipline contained in the Code of Canon Law of 1983 applies.
28. Furthermore, by virtue of its character of special law, within its own area, the Motu Proprio Summorum Pontificum derogates from those provisions of law, connected with the sacred Rites, promulgated from 1962 onwards and incompatible with the rubrics of the liturgical books in effect in 1962.
Confirmation and Holy Orders
29. Permission to use the older formula for the rite of Confirmation was confirmed by the Motu Proprio Summorum Pontificum (cf. art. 9 - 2). Therefore, in the forma extraordinaria, it is not necessary to use the newer formula of Pope Paul VI as found in the Ordo Confirmationis.
30. As regards tonsure, minor orders and the subdiaconate, the Motu Proprio Summorum Pontificum does not introduce any change in the discipline of the Code of Canon Law of 1983; consequently, in Institutes of Consecrated Life and Societies of Apostolic Life which are under the Pontifical Commission Ecclesia Dei, one who has made solemn profession or who has been definitively incorporated into a clerical institute of apostolic life, becomes incardinated as a cleric in the institute or society upon ordination to the diaconate, in accordance with canon 266 - 2 of the Code of Canon Law.
31. Only in Institutes of Consecrated Life and Societies of Apostolic Life which are under the Pontifical Commission Ecclesia Dei, and in those which use the liturgical books of the forma extraordinaria, is the use of the Pontificale Romanum of 1962 for the conferral of minor and major orders permitted.
32. Art. 9 - 3 of the Motu Proprio Summorum Pontificum gives clerics the faculty to use the Breviarium Romanum in effect in 1962, which is to be prayed entirely and in the Latin language.
The Sacred Triduum
33. If there is a qualified priest, a coetus fidelium ("group of faithful"), which follows the older liturgical tradition, can also celebrate the Sacred Triduum in the forma extraordinaria. When there is no church or oratory designated exclusively for such celebrations, the parish priest or Ordinary, in agreement with the qualified priest, should find some arrangement favourable to the good of souls, not excluding the possibility of a repetition of the celebration of the Sacred Triduum in the same church.
The Rites of Religious Orders
34. The use of the liturgical books proper to the Religious Orders which were in effect in 1962 is permitted.
Pontificale Romanum and the Rituale Romanum
35. The use of the Pontificale Romanum, the Rituale Romanum, as well as the Caeremoniale Episcoporum in effect in 1962, is permitted, in keeping with n. 28 of this Instruction, and always respecting n. 31 of the same Instruction.
The Holy Father Pope Benedict XVI, in an audience granted to the undersigned Cardinal President of the Pontifical Commission Ecclesia Dei on 8 April 2011, approved this present Instruction and ordered its publication.
Given at Rome, at the Offices of the Pontifical Commission Ecclesia Dei, 30 April, 2011, on the memorial of Pope Saint Pius V.
