Patron saint in the context of "Florence Baptistery"

Christianity has been the largest religion in Ireland since the 5th century. After a pagan past of Antiquity, missionaries (most famously including Saint Patrick) converted the Irish tribes to Christianity in quick order. This produced a great number of saints in the Early Middle Ages, as well as a faith interwoven with Irish identity for centuries since − though less so in recent times.

Most Christian churches are organized on an "all-Ireland" basis, including both the Republic of Ireland and Northern Ireland. In the 2022 census, 76.1% of residents in the Republic of Ireland identified as Christians: 69.1% as Catholics, 4.2% as Protestants, 2.1% as Orthodox Christians and 0.7% as other Christians. In the 2021 Northern Irish census, 79.7% of residents identified as Christians: 42.3% as Catholics, 16.6% as Prebysterian, 11.5% as Church of Ireland members, 2.4% as Methodist and 6.9% as other Christians. Orthodoxy has been the fastest growing branch of Christianity in Ireland since 1991.

Cluj-Napoca (/ˈkluːʒnæˌpoʊkə/ KLOOZH-na-POH-kə; Romanian: [ˈkluʒ naˈpoka] ), or simply Cluj (Hungarian: Kolozsvár [ˈkoloʒvaːr] , German: Klausenburg), is a city in northwestern Romania. It is the second-most populous city in the country and the seat of Cluj County. Geographically, it is roughly equidistant from Bucharest (445 km; 277 mi), Budapest (461 km; 286 mi) and Belgrade (483 km; 300 mi). Located in the Someșul Mic river valley, the city is considered the unofficial capital of the historical province of Transylvania. For some decades prior to the Austro-Hungarian Compromise of 1867, it was the official capital of the Grand Principality of Transylvania.

As of 2021, 286,598 inhabitants live in the city. The Cluj-Napoca metropolitan area had a population of 411,379 people, while the population of the peri-urban area is approximately 420,000. According to a 2007 estimate, the city hosted an average population of over 20,000 students and other non-residents each year from 2004 to 2007. The city spreads out from St. Michael's Church in Unirii Square, built in the 14th century and named after the Archangel Michael, Cluj's patron saint. The municipality covers an area of 179.52 square kilometres (69.31 sq mi).

The Society of Jesus (Latin: Societas Iesu; abbreviation: S.J. or SJ), also known as the Jesuit Order or the Jesuits (/ˈdʒɛʒuɪts, ˈdʒɛzju-/ JEZH-oo-its, JEZ-ew-; Latin: Iesuitae), is a religious order of clerics regular of pontifical right for men in the Catholic Church headquartered in Rome. It was founded in 1540 by Ignatius of Loyola and six companions, with the approval of Pope Paul III. The Society of Jesus is the largest religious order in the Catholic Church and has played a significant role in education, charity, humanitarian acts and global policies. The Society of Jesus is engaged in evangelization and apostolic ministry in 112 countries. Jesuits work in education, research, and cultural pursuits. They also conduct retreats, minister in hospitals and parishes, sponsor direct social and humanitarian works, and promote ecumenical dialogue.

The Society of Jesus is consecrated under the patronage of Madonna della Strada, a title of the Blessed Virgin Mary, and it is led by a superior general. The headquarters of the society, its general curia, is in Rome. The historic curia of Ignatius is now part of the Collegio del Gesù attached to the Church of the Gesù, the Jesuit mother church.

According to the canonical Gospels, Joseph was a 1st-century Jewish man of Nazareth who was married to Mary, the mother of Jesus, and was the legal father of Jesus.

Joseph is venerated as Saint Joseph in the Catholic Church, Eastern Orthodox Church, Oriental Orthodox Church, Anglicanism and Lutheranism. In Catholic traditions, Joseph is regarded as the patron saint of workers and is associated with various feast days. The month of March is dedicated to Saint Joseph. Pope Pius IX declared him to be both the patron and the protector of the Catholic Church, in addition to his patronages of the sick and of a holy death, due to the belief that he died in the presence of Jesus and Mary. Joseph has become patron of various dioceses and places. Being a patron saint of virgins, he is venerated as "most chaste". The veneration of the pure and most Chaste Heart of Joseph has, in contrast to the Most Sacred Heart of Jesus and the Immaculate Heart of Mary, no liturgical cultus, but is a private devotion.

Joan of Arc (French: Jeanne d'Arc [ʒan daʁk] ; Middle French: Jehanne Darc [ʒəˈãnə ˈdark]; c. 1412 – 30 May 1431) is a patron saint of France, honored as a defender of the French nation for her role in the siege of Orléans and her insistence on the coronation of Charles VII of France during the Hundred Years' War. Claiming to be acting under divine guidance, she became a military leader who gained recognition as a savior of France.

Joan was born to a propertied peasant family at Domrémy in northeast France. In 1428, she requested to be taken to Charles VII, later testifying that she was guided by visions from the archangel Michael, Saint Margaret, and Saint Catherine to help him save France from English domination. Convinced of her devotion and purity, Charles sent Joan, who was about seventeen years old, to Orléans as part of a relief army. She arrived at the city in April 1429, wielding her banner and bringing hope to the demoralized French army. Nine days after her arrival, the English abandoned the siege. Joan encouraged the French to aggressively pursue the English during the Loire Campaign, which culminated in another decisive victory at Patay, opening the way for the French army to advance on Reims unopposed, where Charles was crowned as the king of France with Joan at his side. These victories boosted French morale, paving the way for their final triumph in the Hundred Years' War several decades later.

A patronal feast or patronal festival (Spanish: fiesta patronal; Catalan: festa patronal; Portuguese: festa patronal; Italian: festa patronale; French: fête patronale) is a yearly celebration dedicated – in countries influenced by Christianity – to the 'heavenly advocate' or 'patron' of the location holding the festival, who is a saint or virgin. The day of this celebration is called patronal feast day, patronal day or patron day of said location.

Patronal festivals may reflect national holidays (e.g. the feast of Saint George, patron saint of England, Georgia, Bulgaria, Romania, Portugal, and various regions of Spain), but they usually reflect the celebration of a single city or town.In larger cities, there may even be several festivals, usually about the patron saint of the local parish.

The Patriarchal Cathedral Basilica of Saint Mark (Italian: Basilica Cattedrale Patriarcale di San Marco), commonly known as St Mark's Basilica (Italian: Basilica di San Marco; Venetian: Baxéłega de San Marco), is the cathedral church of the Patriarchate of Venice; it became the episcopal seat of the Patriarch of Venice in 1807, replacing the earlier cathedral of San Pietro di Castello. It is dedicated to and holds the relics of Saint Mark the Evangelist, the patron saint of the city.

The church is located on the eastern end of Saint Mark's Square, the former political and religious centre of the Republic of Venice, and is attached to the Doge's Palace. Prior to the fall of the republic in 1797, it was the chapel of the Doge and was subject to his jurisdiction, with the concurrence of the procurators of Saint Mark for administrative and financial affairs.

The Guild of Saint Luke was the most common name for a city guild for painters and other artists in early modern Europe, especially in the Low Countries. They were named in honor of the Evangelist Luke, the patron saint of artists, who was identified by John of Damascus as having painted the Virgin's portrait.

One of the most famous such organizations was founded in Antwerp. It continued to function until 1795, although by then it had lost its monopoly and therefore most of its power. In most cities, including Antwerp, the local government had given the Guild the power to regulate defined types of trade within the city. Guild membership, as a master, was therefore required for an artist to take on apprentices or to sell paintings to the public. Similar rules existed in Delft, where only members could sell paintings in their city or have a shop. The early guilds in Antwerp and Bruges, setting a model that would be followed in other cities, even had their own showroom market stall from which members could sell their paintings directly to the public.
