Note for the presentation of the Decree Quo magis
approving seven Eucharistic Prefaces
for the forma extraordinaria of the Roman Rite


With the Decree Quo magis of 22 February 2020, the Congregation for the Doctrine of the Faith, which since January 2019 deals with those matters formerly assigned to the Pontifical Commission “Ecclesia Dei”[1], has approved the text of seven new Eucharistic Prefaces to be used ad libitum in the celebration of Mass according to the forma extraordinaria of the Roman Rite[2].

This Decree constitutes the completion of the work previously initiated by the aforementioned Pontifical Commission in order to carry out the mandate given by Pope Benedict XVI to add some additional Prefaces to the Missal of the forma extraordinaria[3].

The studies carried out lead to the selection of a limited number of texts, to be used for particular occasions such as feasts of Saints, votive Masses or ad hoc celebrations, without making any changes to the celebration of the temporal cycle. This choice was made in order to safeguard, through the unity of texts, the unanimity of sentiments and of prayer that are appropriate for the confession of the mysteries of Salvation celebrated in what constitutes the backbone of the liturgical year. In addition, the historical development of the Corpus Præfationum of the Missale Romanum up until the middle of the 20th Century shows a general movement towards the use of new prefaces for occasional celebrations rather than for celebrations of the temporal cycle.

At the same time, the opportunity was taken to extend to all those who celebrate in the Usus Antiquior the faculty to use three other Prefaces previously approved for certain places. These too are texts for determined occasional celebrations.

Four of the newly approved texts, namely the Prefaces de Angelis, de Sancto Ioanne Baptista, de Martyribus and de Nuptiis, are taken from the Missal of the forma ordinaria, and for the most part their central section, known as the “embolism”, appear in ancient liturgical sources. In order to guarantee consistency with the rest of the Corpus Præfationum of the old Missal, in three cases, the standard forms of Preface conclusion of the forma extraordinaria have been used. As indicated, the three other texts (Prefaces de Omnibus Sanctis et Sanctis Patronis, de Sanctissimo Sacramento and de Dedicatione ecclesiæ) are Prefaces previously granted to French and Belgian Dioceses, where they were in use before the post-conciliar liturgical reform. From now on, these may be used wherever Mass is celebrated in the forma extraordinaria.

Two of the seven Prefaces will allow to aptly give more prominence to liturgical celebrations in honour of certain leading figures in God’s design, as manifested in the history of Salvation, namely the Angels and St. John the Baptist, which hitherto both lacked a proper Eucharistic Preface in the Usus Antiquior. In the same vein, the Preface de Martyribus will allow to further underline the eminent character of the gift of martyrdom among the other witnesses of Sequela Christi. Indeed, the first Saints recognized as such were the Martyrs. The Prefaces de Dedicatione Ecclesiæ, de Omnibus Sanctis et Sanctis Patronis and de Sacramento, already in use in some places, will appropriately enrich the celebrations in question with a more suitable eucology than the standard Præfatio Communis. Finally, special note should be taken of the Preface de Nuptiis, which together with the long Nuptial Blessing still in use in Masses pro Sponsis, is to be found – with minor variations – in early Sacramentaries such as the Gelasianum Vetus or the Gregorianum. This ancient Preface, already existing in the forma ordinaria, may therefore now be used in the forma extraordinaria as well.

As indicated above, the use or not, in the relevant circumstances, of the newly approved Prefaces remains an ad libitum choice. Obviously, the celebrant is expected to make use of good pastoral common sense in this regard. In addition, it should be noted that the Decree does not cancel any eventual concessions of proper Prefaces granted in the past, and therefore in those particular cases where there already exists, on the basis of preceding permissions, and for the same liturgical circumstance, a different particular Preface, one may choose between that Preface and the newly approved text.
