Pope John XXIII in the context of "Papal consistory"

The Second Ecumenical Council of the Vatican, commonly known as the Second Vatican Council or Vatican II, was the 21st and most recent ecumenical council of the Catholic Church. The council met each autumn from 1962 to 1965 in St. Peter's Basilica in Vatican City for sessions of 8 and 12 weeks.

Pope John XXIII convened the council because he felt the Church needed "updating" (Italian: aggiornamento). He believed that to better connect with people in an increasingly secularized world, some of the Church's practices needed to be improved and presented in a more understandable and relevant way.

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.

Domenico Tardini (29 February 1888 – 30 July 1961) was a longtime aide to Pope Pius XII in the Secretariat of State. Pope John XXIII named him Cardinal Secretary of State and, in this position the most prominent member of the Roman Curia in Vatican City.

Martín de Porres Velázquez OP (9 December 1579 – 3 November 1639) was a Peruvian lay brother of the Dominican Order who was beatified in 1837 by Pope Gregory XVI and canonized in 1962 by Pope John XXIII. He is the patron saint of Black people, mixed-race people, barbers, innkeepers, public health workers, all those seeking racial harmony, and animals.

He was noted for his work on behalf of the poor, establishing an orphanage and a children's hospital. He maintained an austere lifestyle, which included fasting and abstaining from meat. Among the many miracles attributed to him were those of levitation, bilocation, miraculous knowledge, instantaneous cures, and an ability to communicate with animals.

Ravenna Cathedral or Metropolitan Cathedral of the Resurrection of Our Lord Jesus Christ (Italian: Cattedrale metropolitana della Risurrezione di Nostro Signore Gesù Cristo; Duomo di Ravenna) is a Roman Catholic cathedral dedicated to the Resurrection of Jesus Christ in the city of Ravenna, Italy. Formerly the archiepiscopal seat of the Archdiocese of Ravenna, it is now the seat of the archbishops of Ravenna-Cervia.

It was granted the status of a minor basilica by Pope John XXIII on 7 October 1960. It is the seat of the parish of San Giovanni in Fonte belonging to the Urban Vicariate of the archdiocese of Ravenna-Cervia.

Sotto il Monte (Bergamasque: Sóta 'l Mut; "Under the Mountain"), officially Sotto il Monte Giovanni XXIII, is a comune in northern Italy. Located in the Province of Bergamo in the Region of Lombardy, the town's official name, much like that of Riese Pio X, commemorates the town's most famous son: Angelo Giuseppe Roncalli, who later became Pope John XXIII (Italian: Giovanni XXIII).

The Apostolic Nunciature to Turkey is an ecclesiastical office of the Catholic Church in Turkey. It is a diplomatic post of the Holy See, whose representative is called the Apostolic Nuncio with the rank of an ambassador. The Apostolic Nuncio to Turkey is usually also the Apostolic Nuncio to Azerbaijan and Turkmenistan upon his appointment to said nations.

Papal representation in the area that later became Turkey was initiated with the creation of the Apostolic Delegation to Constantinople in 1868, at a time when the Holy See had largely ceded the management of Church affairs in the region to the French Catholic Church. It was renamed the Apostolic Delegation to Turkey in 1930. In anticipation of the establishment of diplomatic relations, Pope John XXIII created the Apostolic Internunciature to Turkey on 29 February 1960. Pope Paul VI raised it to the full status of Apostolic Nunciature on 30 August 1966.

The Cathedral-Basilica Minore and Parish of the Immaculate Conception, commonly known as Malolos Cathedral, is a Roman Catholic minor basilica and cathedral in the city of Malolos, Bulacan in the Philippines. The cathedral is the see of the Bishop of Malolos, a suffragan of the Archdiocese of Manila. The shrine is dedicated to the Blessed Virgin Mary of the Immaculate Conception.

Pope John XXIII granted the decree Christi Fidelium Consulere which elevated the shrine as a Cathedral on 25 November 1962. Pope John Paul II later raised the shrine to the status of Minor Basilica via decree on 9 April 1999. Pope Benedict XVI granted a decree of Pontifical decree of coronation towards its enshrined Marian image on 11 May 2011. The rite of coronation was executed on 10 March 2012.
