About the same time Quintin Kennedy, Benedictine Abbot of Crossraguel, conferred an immense service on religion by his written apology[17] for the Catholic Church. Starting with the Bible and its relation to ecclesiastical authority, he undertook to show that from the very nature of the case such a book required the presence of a divinely appointed official interpreter, that the reading of the Scriptures was not necessary for salvation though in many cases it might be useful, and that the authority of the Church should not be overthrown even though the existence of scandals among churchmen could not be denied. Turning to his adversaries, he demanded what was the source of all the abuses and scandals which they charged against the Church? Was it not, he asked, the unwarrantable interference of the nobles in the nominations to ecclesiastical benefices, an interference that was responsible for having even children who were too young to hold an apple in their hands appointed to the charge of populous parishes, in order that the relatives of these children might grow rich on the revenues, and was it not the very men who were guilty of such conduct who were loudest in their denunciation of the Church?

As the year (1559) advanced the state of affairs in Scotland became daily more alarming. Preachers were everywhere at work under the protection of the lords. The regent and the French authorities, who had shown a fatal apathy in their dealings with Scottish heretics, began to wake up to the political danger involved in such a movement. A French agent, M.

On their refusal to submit she summoned them to appear at Stirling for trial (10th May). Encouraged by the return of Knox who had landed at Leith early in the same month, and by the armed forces placed at their disposal by some of their principal patrons, they refused to attend and were outlawed. A number of the reforming lords immediately took possession of Perth, and destroyed several Catholic churches in the city. When news of this rising reached the regent she assembled her forces and marched against Perth, but as neither side was anxious for civil war at the time, a truce was agreed upon, and the forces of the regent were allowed to occupy the town. From Perth the reforming lords retreated to St. Andrew's, where they burned and destroyed the altars, pictures, statues, and even the sacred vessels used for religious worship. The abbey church of Scone, in which a long line of Scottish kings had been crowned, was destroyed; Perth and Stirling were seized, and before the
