On The Two Forms Of The Roman Rite (In Latin and English)

Art. 1. Missale Romanum a Paulo VI promulgatum ordinaria expressio “Legis orandi” Ecclesiae catholicae ritus latini est. Missale autem Romanum a S. Pio V promulgatum et a B. Ioanne XXIII denuo editum habeatur uti extraordinaria expressio eiusdem “Legis orandi” Ecclesiae et ob venerabilem et antiquum eius usum debito gaudeat honore. Hae duae expressiones “legis orandi” Ecclesiae, minime vero inducent in divisionem “legis credendi” Ecclesiae; sunt enim duo usus unici ritus romani.

Art 1. The Roman Missal promulgated by Paul VI 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 honour for its venerable and ancient usage. These two expressions of the Church’s Lex orandi will in no any way lead to a division in the Church’s ‘Lex credendi’ (Law of belief). They are, in fact two usages of the one Roman rite.

Proinde Missae Sacrificium, iuxta editionem typicam Missalis Romani a B. Ioanne XXIII anno 1962 promulgatam et numquam abrogatam, uti formam extraordinariam Liturgiae Ecclesiae, celebrare licet. Conditiones vero a documentis antecedentibus “Quattuor abhinc annos” et “Ecclesia Dei” pro usu huius Missalis statutae, substituuntur ut sequitur:

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 and never abrogated, as an extraordinary form of the Liturgy of the Church. The conditions for the use of this Missal as laid down by earlier documents ‘Quattuor abhinc annos’ and ‘Ecclesia Dei,’ are substituted as follows:
