Passage: While the Church of Scotland traces its roots back to the earliest Christians in Scotland, its identity was principally shaped by 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. In 1560, 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. The 1560 Reformation Settlement was not ratified by the crown, as Mary I, a Catholic, refused to do so, and the question of church government also remained unresolved. In 1572 the acts of 1560 were finally approved by the young James VI, but the Concordat of Leith also allowed the crown to appoint bishops with the church's approval. John Knox himself had no clear views on the office of bishop, preferring to see them renamed as 'superintendents' which is a translation of the Greek; but in response to the new Concordat a Presbyterian party emerged headed by Andrew Melville, the author of the Second Book of Discipline.
