/The Book of Discipline/ which contained an exposition of the ecclesiastical policy of the Scottish Reformers was compiled by Knox and his companions. It dealt with the preaching of the Scriptures, the two sacraments Baptism and the Eucharist, the suppression of religious houses of all kinds, the election and appointment of ministers, elders and deacons, and with the means to be provided for their support and for the maintenance of education. Though the separate congregations were left more or less free regarding the kind of religious service that should be followed, the Book of Common Prayer formerly accepted in Scotland was abolished to make way for the Calvinistic Book of Common Order. In the general assemblies of the reformed Church (December 1560-May 1561) decrees were issued for the destruction of the religious houses and of all signs of idolatry, and individuals were appointed to see that these decrees were put into immediate execution.[21] Both parties in Scotland turned instinctively to their queen. Mary had been married in 1558, and in 1559 her husband succeeded to the throne of France under the title of Francis II. A minister was dispatched to inform her of the proceedings in Parliament, but she refused to confirm the terms of the treaty with England, or to sanction the changes that had been decreed. The death of her husband Francis II. (1560) threw her into great grief and forced her to consider the question of returning at once to her kingdom. She believed that many of those who opposed her previously, lest Scotland should become a French province, might now abandon their league with Elizabeth, and welcome home their own lawful sovereign. Nor was there anything at this time to indicate that Mary had any intention of playing the part of a champion of Catholicism,[22] or of running the risk of forfeiting her throne in Scotland or her claims to the English crown by undertaking a campaign against the new religion. Her years of residence at the French court, where religious interests were only too often sacrificed to political designs, could not fail to have produced their natural effect. In February 1561 she sent commissioners to assure the lords of her forgiveness for what they had done, and to empower the Duke of Châtelherault and others to convoke a Parliament in her name. At a meeting of the nobles held in January 1561 her natural brother, Lord James Stuart, was deputed by the lords to offer Mary their allegiance, while the Catholic party including the Earls of Huntly, Atholl, Crawford, Sutherland, and some bishops, dispatched a messenger to warn her against the Congregation, and to place at her disposal a strong force in case she decided to land in the north. But Mary, distrusting the motives of Huntly and his friends, treated their offers of assistance with neglect, and welcomed as her saviour and friend the man who even then was not unwilling to act as a spy on his sister and his queen at the bidding of Elizabeth.
