§ 1. is to determine that these groups do not deny the validity and the legitimacy of the liturgical reform, dictated by Vatican Council II and the Magisterium of the Supreme Pontiffs;
§ 2. is to designate one or more locations where the faithful adherents of these groups may gather for the eucharistic celebration (not however in the parochial churches and without the erection of new personal parishes);
§ 3. to establish at the designated locations the days on which eucharistic celebrations are permitted using the Roman Missal promulgated by Saint John XXIII in 1962.  In these celebrations the readings are proclaimed in the vernacular language, using translations of the Sacred Scripture approved for liturgical use by the respective Episcopal Conferences;
§ 4. to appoint a priest who, as delegate of the bishop, is entrusted with these celebrations and with the pastoral care of these groups of the faithful. This priest should be suited for this responsibility, skilled in the use of the Missale Romanum antecedent to the reform of 1970, possess a knowledge of the Latin language sufficient for a thorough comprehension of the rubrics and liturgical texts, and be animated by a lively pastoral charity and by a sense of ecclesial communion. This priest should have at heart not only the correct celebration of the liturgy, but also the pastoral and spiritual care of the faithful;
§ 5. to proceed suitably to verify that the parishes canonically erected for the benefit of these faithful are effective for their spiritual growth, and to determine whether or not to retain them;
§ 6. to take care not to authorize the establishment of new groups.
Art. 4. Priests ordained after the publication of the present Motu Proprio, who wish to celebrate using the Missale Romanum of 1962, should submit a formal request to the diocesan Bishop who shall consult the Apostolic See before granting this authorization.
Art. 5. Priests who already celebrate according to the Missale Romanum of 1962 should request from the diocesan Bishop the authorization to continue to enjoy this faculty.
Art. 6. Institutes of consecrated life and Societies of apostolic life, erected by the Pontifical Commission Ecclesia Dei, fall under the competence of the Congregation for Institutes of Consecrated Life and Societies for Apostolic Life.
Art. 7. The Congregation for Divine Worship and the Discipline of the Sacraments and the Congregation for Institutes of Consecrated Life and Societies of Apostolic Life, for matters of their particular competence, exercise the authority of the Holy See with respect to the observance of these provisions.
Art. 8. Previous norms, instructions, permissions, and customs that do not conform to the provisions of the present Motu Proprio are abrogated.
