The Church of Scotland (The Kirk o Scotland; Eaglais na h-Alba) is the national church in Scotland.
The Church of Scotland was principally shaped by John Knox, in the Reformation of 1560, when it split from the Catholic Church and established itself as a church in the reformed tradition. The church is Calvinist Presbyterian, having no head of faith or leadership group and believing that God invited the church's adherents to worship Jesus. The annual meeting of its general assembly is chaired by the Moderator of the General Assembly of the Church of Scotland. The Church of Scotland celebrates two sacraments, Baptism and the Lord's Supper, as well as five other rites, such as Confirmation and Matrimony. The church adheres to the Bible and the Westminster Confession of Faith, and is a member of the World Communion of Reformed Churches.
According to traditional Scottish historiography, first Christians in Scotland were converted by Saint Ninian around 400 CE. Early Christian missionaries included Saint Columba, who founded a mission at Iona two centuries later. In 1192, the Papal bull Cum universi separated the Scottish church from the Archbishopric of York, creating an independent national church with no higher authority except the Pope.
The Church of Scotland in its current form traces its origins to the Scottish Reformation of 1560. At that point, many in the then church in Scotland broke with Rome, in a process of Protestant reform led, among others, by John Knox. It reformed its doctrines and government, drawing on the principles of John Calvin which Knox had been exposed to while living in Geneva, Switzerland. An assembly of some nobles, lairds and burgesses, as well as several churchmen, claiming in defiance of the Queen to be a Scottish Parliament, abolished papal jurisdiction and approved the Scots Confession, but did not accept many of the principles laid out in Knox's First Book of Discipline, which argued, among other things, that all of the assets of the old church should pass to the new.
