The Scottish nobles in the pay of Henry VIII. were convinced, as was Henry VIII. himself, that so long as Cardinal Beaton was alive to guide affairs in Scotland no advance could be made in the work of destroying both the religion and the independence of the kingdom. Several of the Scottish enemies of the cardinal entered into communication with Henry himself or with his agents. They offered to murder the cardinal if only Henry promised a sufficient reward, and Henry expressed his approval of the step that was in contemplation.[6] Meanwhile the cardinal was busy preparing schemes for a genuine reform of the Church to be submitted to a national synod called for January 1546, and in making a visitation of his diocese for the purpose of suppressing heresy. George Wishart, formerly a Greek master at Montrose, had returned from the Continent, and had begun to stir up religious dissension in several cities of Scotland. He was the close ally of the Scottish lords who were in the pay of Henry VIII., and he himself was the trusted messenger employed by Crichton, Lord of Brunston, to communicate to the English court the projected murder of Cardinal Beaton and the destruction of certain religious houses in Scotland.[7] The cardinal, who was probably aware of his plots as well as of his preachings, secured his arrest, and brought him to St. Andrew's, where he was tried and executed for heresy (1546). The news of the execution created considerable commotion especially in those centres where Wishart had preached, and gave new impetus to the movement for the assassination of the cardinal. In May 1546 some of the family of Leslie, who had grievances of their own to revenge, with a number of other accomplices secured an entrance to the palace of the Archbishop of St. Andrew's, put his servants and attendants to flight, and murdered him before any help could be summoned. The murder of Cardinal Beaton was an irreparable misfortune for the Catholic Church in Scotland. He was at once an able churchman and a patriot, determined to maintain the independence of his country against the group of pro-English traitors, who were determined to change the religion of Scotland at the bidding of Scotland's greatest enemy. John Knox, a fanatical priest, who had gone over to the new religion, welcomed the murder of the cardinal as a veritable triumph for the gospel and as a "godly act." He hastened to join the murderers who had taken possession of the castle of St. Andrew's, and to whom he preached as the first reformed congregation in Scotland.[8] Henry VIII., no less jubilant for the disappearance of his strongest opponent, was not slow to assist the murderers.
