Solemn Mass in the context of "Mass of Paul VI"

Anglo-Catholicism comprises beliefs and practices that emphasise the Catholic heritage, especially pre-Reformation roots, of the Church of England and other churches within Anglicanism. Anglo-Catholicism claims to restore liturgical and devotional expressions of church life that reflect the ancient practices of the early and medieval church.

The term was coined in the early 19th century, although movements emphasising the Catholic heritage of Anglicanism already existed. Particularly influential in the history of Anglo-Catholicism were the Caroline Divines of the 17th century, the Jacobite Nonjuring schism of the 17th and 18th centuries, and the Oxford Movement, which began at the University of Oxford in 1833 and ushered in a period of Anglican history known as the "Catholic Revival".

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.

The Sisters of the Holy Spirit (Swedish: Helgeandssystrarna) is an Evangelical-Lutheran monastic religious order of nuns of the Church of Sweden, who inhabit Alsike Convent (Swedish: Alsike kloster) in Uppsala County, Sweden. Attached to the convent is Alsike Evangelical Lutheran Church and near the convent is an Evangelical-Lutheran hermitage. The religious habit of The Sisters of the Holy Spirit includes a dove with a cross. The seven canonical hours are prayed daily at Alsike Convent. The nuns are currently three in number. In the Alsike Church, the High Mass is celebrated every Lord's Day (Sunday).

Ite, missa est (English: "Go, it is the dismissal") are the concluding Latin words addressed to the people in the Mass of the Roman Rite in the Catholic Church, as well as in the Divine Service of the Lutheran Church. Until the reforms of 1962, at Masses without the Gloria, Benedicamus Domino was said instead.

The response of the people (or, in the Tridentine Mass, of the servers at Low Mass, the choir at Solemn Mass) to either of the above is Deo gratias ("thanks be to God").

A Pontifical High Mass, also called Solemn Pontifical Mass, is a Solemn or High Mass celebrated by a bishop using certain prescribed ceremonies. Although in modern English the word pontifical is almost exclusively associated with the pope, any bishop may be properly called a pontiff. Thus, the celebrant of a Pontifical High Mass may be the pope, any bishop or any other prelate who is allowed to wear pontificals.
