their clansmen against the old religion by holding up the bishops and clergy as the friends of France and the enemies of Scottish independence. National patriotism was now utilised to help forward the cause of Protestantism, by the very men who a few years before had agreed to betray their country for English gold, and had striven with all their might to make Henry VIII. the protector of Scotland. Some Protestant refugees from England were soon at work in different centres of the country, and encouraged by the regent's policy of neutrality, the man, who was destined to be the apostle of the Reformation, returned to his native land (1555). John Knox,[12] who had shown his devotion to the Gospel by applauding the murder of Cardinal Beaton as a "godly act," and who had founded the first reformed congregation among the murderers gathered in the castle of St. Andrew's, having been released from the French galleys, became a pensioner of Edward VI., and took up his residence in some of the northern towns of England. In a short time he was appointed royal chaplain, and might have had the Bishopric of Rochester had he not expressed the view that such an office was incompatible with devotion to the true evangelical religion. On the accession of Queen Mary he fled from England to Geneva, from which he returned to Scotland in 1555. His violent and overbearing manner, his extravagant denunciations of his opponents, his misrepresentations of their actions and policy, and his readiness both as a speaker and as a writer, qualified him perfectly for the leadership of a revolutionary party, were it not that at certain critical moments his anxiety to avoid personal danger was calculated to shake the confidence of his followers. He was welcomed by many of the discontented nobles, amongst others by Lord Erskine afterwards Earl of Mar, Lord Lorne and his father the Earl of Argyll, Maitland Lord of Lethington, the Earl of Glencairn, and Lord James Stuart prior of St. Andrew's, who as Earl of Moray was soon to betray his sister, Mary Queen of Scots.
