Mass of Paul VI in the context of "Latin liturgical rites"

A missal is a liturgical book containing instructions and texts necessary for the celebration of Mass throughout the liturgical year. Versions differ across liturgical tradition, period, and purpose, with some missals intended to enable a priest to celebrate Mass publicly and others for private and lay use. The texts of the most common Eucharistic liturgy in the world, the Catholic Church's Mass of Paul VI of the Roman Rite, are contained in the 1970 edition of the Roman Missal.

Missals have also been published for earlier forms of the Roman Rite and other Latin liturgical rites. Other liturgical books typically contain the Eucharistic liturgies of other ritual traditions, but missals exist for the Byzantine Rites, Eastern Orthodox Western Rites, Lutheran and Anglican liturgies.

The Tridentine Mass, also known as the Extraordinary Form of the Roman Rite, the usus antiquior (Latin for 'more ancient use'), the Vetus Ordo ('Old Order'), the Traditional Latin Mass (TLM), or the Traditional Rite, is the form of Mass found in the Roman Missal of the Catholic Church codified in 1570 and published thereafter with amendments up to 1962. Celebrated almost exclusively in Ecclesiastical Latin, it was the most widely used Eucharistic liturgy in the world from its issuance in 1570 until its replacement by the Mass of Paul VI promulgated in 1969 (with the revised Roman Missal appearing in 1970).

"Tridentine" is derived from the Latin Tridentinus, lit. 'relating to the city of Trent', where the Council of Trent was held at the height of the Counter-Reformation. In response to a decision of that council, Pope Pius V promulgated the 1570 Roman Missal, making it mandatory throughout the Latin Church, except in places and religious orders with rites or uses from before 1370.

Traditionalist Catholicism is a movement that emphasizes beliefs, practices, customs, traditions, liturgical forms, devotions and presentations of teaching associated with the Catholic Church before the Second Vatican Council (1962–1965). Traditionalist Catholics particularly emphasize the Tridentine Mass, the Roman Rite liturgy largely replaced in general use by the post-Second Vatican Council Mass of Paul VI.

Many traditionalist Catholics disliked the liturgical changes that followed the Second Vatican Council, and prefer to continue to practice pre-Second Vatican Council traditions and forms. Some also see present teachings on ecumenism as blurring the distinction between Catholics and other Christians. Traditional Catholicism is often more conservative in its philosophy and worldview, promoting a modest style of dressing and teaching a complementarian view of gender roles.

The Canon of the Mass (Latin: Canon Missæ), also known as the Canon of the Roman Mass and in the Mass of Paul VI as the Roman Canon or Eucharistic Prayer I, is the oldest anaphora used in the Roman Rite of Mass. The name Canon Missæ was used in the Tridentine Missal from the first typical edition of Pope Pius V in 1570 to that of Pope John XXIII in 1962 to describe the part of the Mass of the Roman Rite that began after the Sanctus with the words Te igitur. All editions preceding that of 1962 place the indication "Canon Missae" at the head of each page from that point until the end of the Mass; that of 1962 does so only until the page preceding the Pater Noster and places the heading "Ordo Missae" on the following pages.

Before 1962, there were divergent opinions about the point where the Canon of the Mass ended. Some considered that it ended where indicated in the 1962 Roman Missal, others where indicated in the earlier editions from 1570 onwards (the end of Mass), others at the conclusion of the Embolism (Libera nos...) that expands on the final "Sed libera nos a malo" petition of the Pater Noster.

Solemn Mass (Latin: missa solemnis) is the full ceremonial form of a Mass, predominantly associated with the Tridentine Mass where it is celebrated by a priest with a deacon and a subdeacon, requiring most of the parts of the Mass to be sung, and the use of incense. It is also called High Mass or Solemn High Mass.

These terms distinguish it from a Low Mass and Missa cantata. The parts assigned to the deacon and subdeacon are often performed by priests in vestments proper to those roles. A Solemn Mass celebrated by a bishop has its own particular ceremonies and is referred to as a Solemn Pontifical Mass. Within the Roman Rite, the history of the Solemn Mass has been traced to the 7th century in the Gregorian Sacramentary and Ordo Romanus Primus, followed by several centuries of adapting these pontifical liturgies. Eventually, the proliferation of multiple parish churches within the same cities saw these liturgies further adapted so that the average priest could celebrate them. By the 13th century, those Masses with ceremonial more closely following that of the pontifical liturgies were identified as "Solemn" or "High Masses" in contrast with simpler "Low Masses". In the Catholic Church, since the promulgation of the 1969 Roman Missal, much of the Solemn Mass's ceremonial has fallen into obsolescence and disuse.

A Requiem (Latin: rest) or Requiem Mass, also known as Mass for the dead (Latin: Missa pro defunctis) or Mass of the dead (Latin: Missa defunctorum), is a Mass of the Catholic Church offered for the repose of the souls of the deceased, using a particular form of the Roman Missal. It is usually celebrated in the context of a funeral (where in some countries it is often called a Funeral Mass).

Musical settings of the propers of the Requiem Mass are also called Requiems, and the term has subsequently been applied to other musical compositions associated with death, dying, and mourning, even when they lack religious or liturgical relevance.

The gradual (Latin: graduale or responsorium graduale) is a certain chant or hymn in liturgical Christian worship. It is practiced in the Catholic Mass, Lutheran Divine Service, Anglican service and other traditions. It gets its name from the Latin gradus (meaning "step") because it was once chanted on the step of the ambo or altar. It is customarily placed after a reading of scripture.

In the Tridentine Mass, it is sung after the reading or chanting of the epistle and before the Alleluia, or, during penitential seasons, before the tract. In the Mass of Paul VI, the gradual is usually replaced with the responsorial psalm. Although the Gradual remains an option in the Mass of Paul VI, its use is extremely rare outside monasteries. The gradual is part of the proper of the Mass.
