Catholic Church in Scotland in the context of "Scottish Enlightenment"

Christianity is the largest religion in the United Kingdom. Results of the 2021 Census for England and Wales showed that Christianity is the largest religion (though it makes up less than half of the population at 46.2%), followed by the non-religious (37.2%), Islam (6.5%), Hinduism (1.7%), Sikhism (0.9%), Buddhism (0.5%), Judaism (0.5%), and others (0.6%). Among Christians, Anglicanism is the most common denomination, with 53% of Christian believers in the UK identifying with this denomination as of 2023, followed by Catholicism, Presbyterianism, Methodism, Unitarianism, and Baptists. Results for the 2022 census in Scotland indicated that the majority (51%) had no religion, but that 38.8% of the Scottish population identified as Christian (of which 20% identified with the Church of Scotland and 13% with the Catholic Church). In Northern Ireland, Christianity is the largest religion (79.7%) followed by non-religious (17.4%), other religions (1.3%), and not stated (1.5%), as of 2021.

The Scalan was a Scottish Catholic seminary and one of the few places where underground education by the Catholic Church in Scotland was kept alive during the anti-Catholic persecutions of the 16th-19th century.

John Geddes (9 September 1735 – 11 February 1799) was a Scottish Catholic prelate who served as Coadjutor Vicar Apostolic of the Lowland District from 1779 to 1797. He was also rector of the Royal Scots College, Valladolid, from 1771 to 1780. In addition to his published writings about the history of the Catholic Church in Scotland and efforts to achieve Catholic Emancipation, Geddes is particularly important for his partially extant diary of Edinburgh intellectual life during the Scottish Enlightenment and for his friendship with Scottish national poet Robert Burns, from whom he received the now priceless volume known as The Geddes Burns.

As of the 2022 census, "None" was the largest category of belief in Scotland, chosen by 51.1% of the Scottish population when asked: "What religion, religious denomination or body do you belong to?" This represented a significant increase from the 2011 figure of 36.7%. 38.8% identified as Christian with most of them declaring affiliation with the Church of Scotland (52.5% of Christians; 20.4% of the total population) and the Catholic Church (34.3% of Christians; 13.3% of the total population). The only other religious persuasions with more than 1% affiliation were 'Other Christian' and Muslim at 5.1% and 2.2% of the total population, respectively.

The Church of Scotland, a Presbyterian denomination often known as The Kirk, is recognised in law as the national church of Scotland. It is not an established church and is independent of state control. The Catholic Church is especially important in West Central Scotland and parts of the Highlands. Scotland's third largest church is the Scottish Episcopal Church. There are also multiple smaller Presbyterian churches, all of which either broke away from the Church of Scotland or themselves separated from churches which previously did so. The 2019 Scottish Household survey had a rate of the proportion of adults reporting not belonging to a religion of 56%. The trend of declining religious belief coincided with a sharp decrease since 2009 in the proportion of people who report that they belong to the Church of Scotland, from 34% to 20% of adults.

John Knox (c. 1514 – 24 November 1572) was a Scottish minister, Reformed theologian, and writer who was a leader of the country's Reformation. He was the founder of the Church of Scotland.

Born in Giffordgate, a street in Haddington, East Lothian, Knox is believed to have been educated at the University of St Andrews and worked as a notary-priest. Influenced by early church reformers such as George Wishart, he joined the movement to reform the Scottish Church. He was caught up in the ecclesiastical and political events that involved the murder of Cardinal David Beaton in 1546 and the intervention of the regent Mary of Guise. He was taken prisoner by French forces the following year and exiled to England on his release in 1549.

The Archdiocese of St Andrews (originally the Diocese of St Andrews) was a territorial episcopal jurisdiction of the Catholic Church in early modern and medieval Scotland. It was the largest, most populous and wealthiest diocese of the medieval Scottish Catholic church, with territory in eastern Scotland stretching from Berwickshire and the Anglo-Scottish border to Aberdeenshire.

Although not an archdiocese until 1472, St Andrews was recognised as the chief see of the Scottish church from at least the 11th century. It came to be one of two archdioceses of the Scottish church, from the early 16th century having the bishoprics of Aberdeen, Brechin, Caithness, Dunblane, Dunkeld, Moray, Orkney and Ross as suffragans.
