The Book of Discipline refers to two works regulative of ecclesiastical order in the Church of Scotland, known as The First Book of Discipline (1560) and The Second Book of Discipline (1578), drawn up and printed in the Scottish Reformation. The first was drafted by a committee of "six Johns", including leading reformer John Knox. It set out a system of Presbyterian polity on the Geneva model, but the lack of funds meant its programme of clerical organisation and education was largely abandoned. The second book was adopted after the forced abdication of Mary Queen of Scots and was much more clearly Presbyterian in outlook. It placed church supervision fully in the hands of groups of elected church leaders in presbyteries.
In 1560, following the death of the regent Mary of Guise, who ruled on behalf of her daughter Mary, Queen of Scots who was in France and the defeat of French forces at the Siege of Leith, the reform-minded Lords of the Congregation were in the ascendency in Scotland. The Scottish Parliament met in Edinburgh 1 August 1560. Ignoring the provisions of the Treaty of Edinburgh, on 17 August, Parliament approved a Reformed Confession of Faith (the Scots Confession), and on 24 August it passed three Acts that abolished the old faith in Scotland. Under these, all previous acts not in conformity with the Reformed Confession were annulled; the sacraments were reduced to two (Baptism and Communion) to be performed by reformed preachers alone; the celebration of the Mass was made punishable by a series of penalties (ultimately death) and Papal jurisdiction in Scotland was repudiated. The Queen declined to endorse the acts that Parliament had passed and the new kirk existed in a state of legal uncertainty.
