Extraordinary Form

On the Extraordinary Form of the Eucharist

One of the liturgical books of the Roman rite is the Roman Missal, which developed in the city of Rome and, with the passing of the centuries, little by little took forms very similar to that it has had in recent times."It was towards this same goal that succeeding Roman Pontiffs directed their energies during the subsequent centuries in order to ensure that the rites and liturgical books were brought up to date and when necessary clarified. From the beginning of this century they undertook a more general reform." Thus our predecessors Clement VIII, Urban VIII, St. Pius X, Benedict XV, Pius XII and Blessed John XXIII all played a part.

In more recent times, Vatican Council II expressed a desire that the respectful reverence due to divine worship should be renewed and adapted to the needs of our time. Moved by this desire our predecessor, the Supreme Pontiff Paul VI, approved, in 1970, reformed and partly renewed liturgical books for the Latin Church. These, translated into the various languages of the world, were willingly accepted by bishops, priests and faithful. John Paul II amended the third typical edition of the Roman Missal. Thus Roman pontiffs have operated to ensure that "this kind of liturgical edifice . . . should again appear resplendent for its dignity and harmony."

But in some regions, no small numbers of faithful adhered and continue to adhere with great love and affection to the earlier liturgical forms. These had so deeply marked their culture and their spirit that in 1984 the Supreme Pontiff John Paul II, moved by a concern for the pastoral care of these faithful, with the special indult Quattuor abhinc annos, issued by the Congregation for Divine Worship, granted permission to use the Roman Missal published by Blessed John XXIII in the year 1962. Later, in the year 1988, John Paul II with the Apostolic Letter given as Motu Proprio, Ecclesia Dei, exhorted bishops to make generous use of this power in favor of all the faithful who so desired.

Following the insistent prayers of these faithful, long deliberated upon by our predecessor John Paul II, and after having listened to the views of the Cardinal Fathers of the Consistory of 22 March 2006, having reflected deeply upon all aspects of the question, invoked the Holy Spirit and trusting in the help of God, with these Apostolic Letters the Roman Missal promulgated by Paul VI was identified is the ordinary expression of the "Lex orandi" (Law of prayer) of the Catholic Church of the Latin rite. Nonetheless, the Roman Missal promulgated by St. Pius V and reissued by Bl. John XXIII is to be considered as an extraordinary expression of that same "Lex orandi," and must be given due honor for its venerable and ancient usage. It is, therefore, permissible to celebrate the Sacrifice of the Mass following the typical edition of the Roman Missal promulgated by Bl. John XXIII in 1962 under certain conditions as specified in the Motu Proprio Summorum Pontificum.
