John Knox in the context of "Presbyterian Church (USA)"

Mary, Queen of Scots (8 December 1542 – 8 February 1587), also known as Mary Stuart or Mary I of Scotland, was Queen of Scotland from 14 December 1542 until her forced abdication on 24 July 1567.

The only surviving legitimate child of James V of Scotland, Mary was six days old when her father died and she inherited the throne. During her childhood, Scotland was governed by regents, first by the heir to the throne, James Hamilton, Earl of Arran, and then by her mother, Mary of Guise. In 1548, she was betrothed to Francis, the Dauphin of France, and was sent to be brought up in France, where she would be safe from invading English forces during the Rough Wooing. Mary married Francis in 1558, becoming queen consort of France from his accession in 1559 until his death in December 1560. Widowed, Mary returned to Scotland in August 1561. The tense religious and political climate following the Scottish Reformation that Mary encountered on her return to Scotland was further agitated by prominent Scots such as John Knox, who openly questioned whether her subjects had a duty to obey her. The early years of her personal rule were marked by pragmatism, tolerance, and moderation. She issued a proclamation accepting the religious settlement in Scotland as she had found it upon her return, retained advisers such as James Stewart, Earl of Moray (her illegitimate half-brother), and William Maitland of Lethington, and governed as the Catholic monarch of a Protestant kingdom.

Presbyterian or presbyteral polity is a method of church governance ("ecclesiastical polity") typified by the rule of assemblies of presbyters, or elders. Each local church is governed by a body of elected elders usually called the session (or consistory), though other terms, such as church board, may apply. Groups of local churches are governed by a higher assembly of elders known as the presbytery or classis; presbyteries can be grouped into a synod, and presbyteries and synods nationwide often join together in a general assembly. Responsibility for conduct of church services is reserved to an ordained minister or pastor known as a teaching elder, or a minister of the word and sacrament.

Presbyterian polity was developed as a rejection of governance by hierarchies of single bishops (episcopal polity), but also differs from the congregationalist polity in which each congregation is independent. In contrast to the other two forms, authority in the presbyterian polity flows both from the top down (as higher assemblies exercise limited but important authority over individual congregations, e.g., only the presbytery can ordain ministers, install pastors, and start up, close, and approve relocating a congregation) and from the bottom up (e.g., the moderator and officers are not appointed from above but are rather elected by and from among the members of the assembly). This theory of governance developed in Geneva under John Calvin and was introduced to Scotland by John Knox after his period of exile in Geneva. It is strongly associated with French, Dutch, Swiss and Scottish Reformation movements, and the Reformed and Presbyterian churches.

The Royal Burgh of Haddington (Scots: Haidintoun, Scottish Gaelic: Baile Adainn) is a town in East Lothian, Scotland. It is the main administrative, cultural and geographical centre for East Lothian. It lies about 17 miles (27 kilometres) east of Edinburgh. The name Haddington is Anglo-Saxon, dating from the sixth or seventh century AD when the area was incorporated into the Kingdom of Bernicia. The town, like the rest of the Lothian region, was ceded by King Edgar of England and became part of Scotland in the tenth century. Haddington received Burgh status, one of the earliest to do so, during the reign of David I (1124–1153), giving it trading rights which encouraged its growth into a market town.

Today, Haddington is a small town with a population of about 10,000 people, but during the High Middle Ages it was the fourth-biggest town in Scotland (after Aberdeen, Roxburgh and Edinburgh). In the middle of the town is the Haddington Town House, completed in 1745 based on a plan by William Adam. When first built, it contained markets on the ground floor, and an assembly hall on the first floor to which improvements were made in 1788, and a spire was added in 1831. Nearby is the corn exchange (1854) and the county courthouse (1833). Other notable nearby sites include: the Jane Welsh Carlyle House; Mitchell's Close; and a building on the High Street that was the birthplace of the author and government reformer Samuel Smiles and is marked by a commemorative plaque. John Knox was probably born in Haddington and Knox Academy, the local high school, is named after him.

Anti-Catholicism in the United Kingdom dates back to the martyrdom of Saint Alban in the Roman era. Attacks on the Church from a Protestant angle mostly began with the English and Irish Reformations which were launched by King Henry VIII and the Scottish Reformation which was led by John Knox. Within England, the Act of Supremacy 1534 declared the English crown to be "the only supreme head on earth of the Church in England" in place of the Pope. Any act of allegiance to the latter was considered treasonous because the papacy claimed both spiritual and political power over its followers. Ireland was brought under direct English control starting in 1536 during the Tudor conquest of Ireland. The Scottish Reformation in 1560 abolished Catholic ecclesiastical structures and rendered Catholic practice illegal in Scotland. Today, anti-Catholicism remains present in the United Kingdom, particularly in Scotland and Northern Ireland.

Anti-Catholicism among many of the English was grounded in the fact that the Holy See sought not only to regain its traditional religious and spiritual authority over the English Church, but was also covertly backing regime change in alliance with Philip II of Spain as a means to ending the religious persecution of Catholics throughout the British Isles. In 1570, Pope Pius V declared Elizabeth I who ruled England and Ireland deposed and excommunicated with the papal bull Regnans in Excelsis, which also released all Elizabeth's subjects from their allegiance to her. This rendered conditions impossible even for Elizabeth's subjects, like Richard Gwyn and Robert Southwell, who were completely apolitical but persisted in their allegiance to the Catholic Church in England and Wales, as the Queen and her officials refused to accept that her subjects could maintain both allegiances at once. The Recusancy Acts, legally coercing English, Welsh, and Irish citizens to conform to Anglicanism and attend weekly services on pain of prosecution for high treason, date from Elizabeth's reign. Later, regicide and decapitation strike plots organized by persecuted Catholics were heavily exploited by the Crown for propaganda and further fuelled anti-Catholicism in England. In 1603, James VI of Scotland became also James I of England and Ireland.

St Giles' Cathedral (Scottish Gaelic: Cathair-eaglais Naomh Giles), also known as High Kirk of Edinburgh, is one of three cathedrals in Edinburgh, Scotland. The existing building was begun in the 14th century and extended until the early 16th century; significant alterations were undertaken in the 19th and 20th centuries, including the addition of the Thistle Chapel. St Giles' is closely associated with many events and figures in Scottish history, including John Knox, who served as the church's minister after the Scottish Reformation. The cathedral is administered by the Church of Scotland.

It was probably founded in the 12th century and dedicated to Saint Giles. The church was elevated to collegiate status by Pope Paul II in 1467. In 1559, the church became Protestant with John Knox, the foremost figure of the Scottish Reformation, as its minister. After the Reformation, St Giles' was internally partitioned to serve multiple congregations as well as secular purposes, such as a prison and as a meeting place for the Parliament of Scotland. In 1633, Charles I made St Giles' the cathedral of the newly created Diocese of Edinburgh. Charles' attempt to impose doctrinal changes on the presbyterian Scottish Kirk, including a Prayer Book causing a riot in St Giles' on 23 July 1637, which precipitated the formation of the Covenanters and the beginnings of the Wars of the Three Kingdoms. St Giles' role in the Scottish Reformation and the Covenanters' Rebellion has led to its being called "the Mother Church of World Presbyterianism".

The Scottish Reformation was the process whereby Scotland broke away from the Catholic Church, and established the Protestant Church of Scotland. It forms part of the wider European 16th-century Protestant Reformation.

From the first half of the 16th century, Scottish scholars and religious leaders were influenced by the teachings of the Protestant reformer, Martin Luther. In 1560, a group of Scottish nobles known as the Lords of the Congregation gained control of government. Under their guidance, the Scottish Reformation Parliament passed legislation that established a Protestant creed, and rejected Papal supremacy, although these were only formally ratified by James VI in 1567.
