Western Rite Orthodoxy in the context of "Angelus"

The epiclesis (also spelled epiklesis; from Ancient Greek: ἐπίκλησις, lit. 'surname' or 'invocation') refers to the invocation of one or several gods. In ancient Greek religion, the epiclesis was the epithet used as the surname given to a deity in religious contexts. The term was borrowed into the Christian tradition, where it designates the part of the Anaphora (Eucharistic Prayer) by which the priest invokes the Holy Spirit (or the power of God's blessing) upon the Eucharistic bread and wine in some Christian churches. In most Eastern Christian traditions, the Epiclesis comes after the Anamnesis (remembrance of Jesus' words and deeds); in the Western Rite it usually precedes. In the historic practice of the Western Christian Churches, the consecration is effected at the Words of Institution, though during the rise of the Liturgical Movement, many denominations introduced an explicit epiclesis in their liturgies.

Latin liturgical rites, or Western liturgical rites, is a large family of liturgical rites and uses of public worship employed by the Latin Church, the largest particular church sui iuris of the Catholic Church, that originated in Europe where the Latin language once dominated and further by Western Rite Orthodoxy and Independent and Old Catholicism. Its language is now known as Ecclesiastical Latin. The most used rite is the Roman Rite.

The Latin rites were for many centuries no less numerous than the modern Eastern Catholic liturgical rites. The number of Latin rites and uses is now much reduced. In the aftermath of the Council of Trent, in 1568 and 1570 Pope Pius V suppressed the breviaries and missals that could not be shown to have an antiquity of at least two centuries in favor of the Roman Missal and Roman Breviary. Many local rites that remained legitimate even after this decree were abandoned voluntarily, especially in the 19th century, in favor of the Tridentine Mass and other Roman Rite rituals. In the second half of the 20th century, most of the religious orders that had a distinct liturgical rite chose to adopt in its place the Roman Rite as revised in accordance with the decrees of the Second Vatican Council (see Mass of Paul VI). A few such liturgical rites persist today for the celebration of Mass, since 1965–1970 in revised forms, but the distinct liturgical rites for celebrating the other sacraments have been almost completely abandoned.

Mass is the main Eucharistic liturgical service in many forms of Western Christianity. The term Mass is commonly used in the Catholic Church, Western Rite Orthodoxy, Old Catholicism, and Independent Catholicism. The term is also used in many Lutheran churches, as well as in some Anglican churches, and on rare occasion by other Protestant churches.

Other Christian denominations may employ terms such as Divine Service or worship service (and often just "service"), rather than the word Mass. For the celebration of the Eucharist in Eastern Christianity, including Eastern Catholic Churches, other terms such as Divine Liturgy, Holy Qurbana, Holy Qurobo and Badarak (or Patarag) are typically used instead.

The Ambrosian Rite (Italian: Rito Ambrosiano) is a Latin liturgical rite of the Catholic Church and the Eastern Orthodox Church (specifically The Divine Liturgy of Saint Ambrose). The rite is named after Saint Ambrose, a bishop of Milan in the fourth century. It is used by around five million Catholics in the greater part of the Archdiocese of Milan (excluding Monza, Treviglio and Trezzo sull'Adda), in some parishes of the Diocese of Como, Bergamo, Novara, Lodi, in the Diocese of Lugano, Canton of Ticino, Switzerland, less prominently in some Western Rite orthodox parishes and on special occasions of other jurisdictions.

The Ambrosian Rite has risked suppression at various points in its history. It was reformed after the Second Vatican Council (Pope Paul VI belonged to the Ambrosian Rite, having previously been Archbishop of Milan). In the 20th century, it also gained prominence and prestige from the attentions of two other scholarly Archbishops of Milan: Achille Ratti, later Pope Pius XI, and the Blessed Ildefonso Schuster, both of whom were involved in studies and publications on the rite.

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 Mozarabic Rite (Spanish: rito mozárabe, Portuguese: rito moçárabe, Catalan: ritu mossàrab), officially called the Hispanic Rite (Spanish: Rito hispánico, Portuguese: rito hispânico, Catalan: ritu hispà), and in the past also called the Visigothic Rite, is a liturgical rite of the Latin Church once used generally in the Iberian Peninsula (Hispania), in what is now Spain and Portugal. While the liturgy is often called 'Mozarabic' after the Christian communities that lived under Muslim rulers in Al-Andalus that preserved its use, the rite itself developed before and during the Visigothic period. After experiencing a period of decline during the Reconquista, when it was superseded by the Roman Rite in the Christian states of Iberia as part of a wider programme of liturgical standardization within the Catholic Church, efforts were taken in the 16th century to revive the rite and ensure its continued presence in the city of Toledo, where it is still celebrated today. It is also celebrated on a more widespread basis throughout Spain and, by special dispensation, in other countries, though only on special occasions.

In addition to its use within the Catholic Church, the rite (or elements from it) has also been adopted by Western Rite Orthodox congregations and the Spanish Reformed Episcopal Church.

Julian Joseph Overbeck (1820–1905) was a Roman Catholic priest who converted to Eastern Orthodoxy and became a pioneer of Western Rite Orthodoxy.
