the Articles of Leith signed 25 July 1559, and Mary of Guise promised freedom of conscience. Knox knew that the Queen Regent would ask for help from France, so he negotiated by letter under the assumed name John Sinclair with William Cecil, Elizabeth's chief adviser, for English support. Knox sailed secretly to Lindisfarne, off the northeast coast of England at the end of July, to meet James Croft and Sir Henry Percy at Berwick upon Tweed. Knox was indiscreet and news of his mission soon reached Mary of Guise. He returned to Edinburgh telling Croft he had to return to his flock, and suggested that Henry Balnaves should go to Cecil.

A week later, the Parliament passed three acts in one day: the first abolished the jurisdiction of the Pope in Scotland, the second condemned all doctrine and practice contrary to the reformed faith, and the third forbade the celebration of Mass in Scotland. Before the dissolution of Parliament, Knox and the other ministers were given the task of organising the newly reformed church or the Kirk. They would work for several months on the Book of Discipline, the document describing the organisation of the new
