The return of the young queen to Scotland (August, 1561) revived all the old dissensions, and introduced new elements into the strife of parties. By every opinion she held on religion, on the relations of prince and subject, on the fundamental principles of life, Mary was separated as by an abyss from the party represented by Knox. If we may judge from the language which each used of the other, Knox and she failed to find one point on which genial intercourse was possible. As the minister of St. Giles (then the only Reformed church in Edinburgh), Knox believed that Mary was his special charge. Her personal conduct, therefore, no less than her public policy, were made the subject of his most stringent criticism; and during the six years of her reign his attitude toward her was that of uncompromising insistence. The celebration of mass in Holyrood Chapel, in defiance of the late religious settlement, first roused his wrath; and a sermon delivered by him in St. Giles led to the first of those famous interviews with Mary, the record of which makes such a remarkable portion of his "History of the Reformation." The division of ecclesiastical property, by which those in actual possession received two-thirds, the reformed ministers one-third, was a further ground of quarrel with the new government. The delay of Mary to confirm the late religious settlement also gave rise to the greatest anxiety on the part of Knox and his brother ministers. In view of the precarious interests of the great cause, Knox spoke out with such frankness as to alienate the most powerful noble in the country, and the one whom he respected most--Lord James Stuart, afterward the Regent Moray. The marriage of Mary with Darnley (1565), again, however, led them to common counsels, as both saw in this marriage the most serious menace against the new religion. In the subsequent revolt, headed by Moray and the other Protestant nobles, Knox nevertheless took no part, and remained at his charge in Edinburgh. But after the murder of Rizzio, he deemed it wise, considering Mary's disposition toward him, to withdraw to Kyle, in Ayrshire, where he appears to have written the greater part of his history.
