Quo primum (from the first) is the incipit of an Apostolic constitution in the form of a papal bull issued by Pope Pius V on 14 July 1570. It promulgated the Roman Missal, and made its use obligatory throughout the Latin Church of the Catholic Church, except where there existed a different Mass liturgy of the Latin Church of at least two hundred years standing.
The declared reason for this measure was this: "It is most becoming that there be in the Church... only one rite for the celebration of Mass." However, he made the exception mentioned, which permitted the survival, within limited areas or in celebrations by members of certain religious orders, of Latin liturgical rites other than the Roman Rite, rites such as the Ambrosian and Mozarabic Rites, that of the Diocese of Lyon and certain Catholic Order Rites. Some of these dioceses and religious orders have since decided to adopt the Roman Rite. Others preferred not to avail themselves of the exemption to which they were entitled and instead to adopt the Roman Missal immediately.
Thus, although the bull Quo primum contained expressions such as "Let all everywhere adopt and observe what has been handed down by the Holy Roman Church, the Mother and Teacher of the other Churches, and let Masses not be sung or read according to any other formula than that of this Missal published by Us. This ordinance applies henceforth, now, and forever, throughout all the provinces of the Christian world", exceptions were allowed from the start, and not all priests—even those within Latin Rites—were obliged to adopt the Missal of Pius V.[1]
In the bull Pope Pius V declared:
"By this present Constitution, which will be valid henceforth, now, and forever, We order and enjoin that nothing must be added to Our recently published Missal, nothing omitted from it, nor anything whatsoever be changed within it."And he concluded:
"No one whosoever is permitted to alter this notice of Our permission, statute, ordinance, command, precept, grant, indult, declaration, will, decree, and prohibition. Should anyone dare to contravene it, let him know that he will incur the wrath of Almighty God and of the Blessed Apostles Peter and Paul."By this, he forbade alterations by other authorities, ecclesiastical or civil, or by private individuals. He gives a list of ecclesiastical dignitaries who, he says, may not alter his Missal, even of the level of cardinal, or another ("each and every patriarch, administrator, and all other persons or whatever ecclesiastical dignity they may be, be they even cardinals of the Holy Roman Church, or possessed of any other rank or pre-eminence"). Pius V himself instituted a minor inclusion of a Feast day after the victory of Lepanto in the following year, he added to it the feast of Our Lady of Victory. In 1585, Pope Sixtus V restored the feast of the Presentation of the Virgin Mary, which Pope Pius V had removed from the Missal. Only 34 years after the publication of Quo primum, Pope Clement VIII made a general revision of the Roman Missal, as did Pope Urban VIII 30 years later. These additions of Feast days and revision were not an abrogation of Quo Primum, but rather, within its purview, and affirmations of, its theological underpinnings.
Further editions of the Roman Missal were published in 1884 by Pope Leo XIII, in 1920 by Pope Benedict XV and in 1962 by Pope John XXIII with certain differences.
The apostolic constitution Missale Romanum of Pope Paul VI replaced the Tridentine Mass with the new Mass of Paul VI, as requested by the Second Vatican Council through the Constitution Sacrosanctum Concilium. In Missale Romanum, Paul VI states that the new liturgical norms are to be "firm and effective, now and in the future, notwithstanding, to the extent necessary, the apostolic constitutions and ordinances issued by Our predecessors, and other prescriptions, even those deserving particular mention and derogation."[2]
In his motu proprio Summorum Pontificum, Pope Benedict XVI liberalised the use of the 1962 version of the Roman Missal, stating that it was never abrogated and was thus to be considered as the "extraordinary form of the Roman Rite", whereas the Mass of Paul VI was to be considered as the "ordinary form of the Roman Rite".[3]
These provisions were later reversed by Pope Francis in his motu proprio Traditionis custodes, stating that "the liturgical books promulgated by Saint Paul VI and Saint John Paul II, in conformity with the decrees of Vatican Council II, are the unique expression of the lex orandi of the Roman Rite" and that all provisions contrasting with that were abrogated.[4]
