But there was no need for him to throw his life away as a gratuitous sacrifice, and therefore, when he was compelled to seek safety from his persecutors by removing from place to place, and out of weariness was minded to go to Germany, he consented, at the earnest solicitations of the parents of his pupils, to find protection in the Castle of St. Andrews. Let it be noted, however, that he did not enter that stronghold until the 10th of April, 1547, that is, more than ten months after Beaton's murder, and therefore he is not to be reckoned among those who had concocted and carried out the assassination of that prelate. He was at that date in too obscure a station to be in any way, even the most remote, associated with those who had committed that foul murder, and he went to St. Andrews simply that he might be able to carry on uninterruptedly the education of his pupils. Accordingly, so soon as he was fairly settled there, he resumed the regular routine of his work with them. What that was he has himself informed us in these words: "Besides their grammar and other humane authors" (that is, authors in what were then called the humanity classes) "he read unto them a catechism, an account whereof he caused them to give publicly in the parish church of St. Andrews. He read moreover unto them the Gospel of John proceeding where he" (had) {15} "left" (off) "at his departing from Longniddry where before his residence was, and that lecture he read in the chapel within the castle at a certain hour." These public exercises attracted to them a large number of those who were then sojourning in the castle, among whom were Henry Balnaves of Halhill, a distinguished jurist, who had been already, and was to be again, one of the judges of the court of session, and John Rough, who was the stated preacher to the congregation within the castle. These men were greatly impressed alike with the matter, the method, and the manner of delivery of the lectures, and seeing his fitness for the work, they earnestly entreated Knox to enter at once upon the office of the ministry. But he declared that "he would not run where God had not called him," and peremptorily refused to accede to their request. Upon this they took counsel with Sir David Lindsay, of the Mount, and others, and ultimately agreed that Rough, without giving any formal warning that he was about to do anything of the kind, should address to Knox a special public call in the name and before the face of the congregation. Accordingly, in the presence of the people, and after having preached a sermon on the election of ministers, Rough turned to Knox and said, "Brother, ye shall not be offended, albeit that I speak unto you that which I have in charge even from all those that are here present, which is this: In the name of God and of His Son Jesus Christ, and in the name of these that presently call you by my mouth, I charge you that ye refuse {16} not this holy vocation, but that, as ye tender
