We have no details concerning his conversion from the Romish to the Protestant faith. According to one authority it was Thomas Guillaume who was "the first to give Mr. Knox a taste of the truth." That eloquent preacher,—a native of East Lothian, who had risen to a high place in the order of the Dominicans,—had through the influence of the party of progress been appointed chaplain to the Regent Arran at the time when that weak ruler was favouring the Reformers. Knox himself has described him as "a man of solid judgment, reasonable letters (as for that age), and of prompt and good utterance; his doctrine was wholesome without great vehemency against superstition." It does not appear, however, from anything he says that he ever came personally into contact with him, though it is possible that some of those clear expositions of Scripture for which Guillaume was so esteemed may have been heard by him, and may have produced a deep impression on his mind. But beyond all question George Wishart was the true spiritual father of John Knox. The preaching and companionship of that earnest man during that journey through the Lothians, which ended in his apprehension at Ormiston, did more for Knox than any other human instrumentality whatever. They wrought conviction in him, and brought him out into decision, so that from the moment when these two men parted from each other for the last time at the church of Haddington, it was no longer possible for Knox to return into the position of comparative obscurity from which he had emerged to become the body-guard of Wishart. He had come prominently out on the side of the Reformation, and the martyrdom of his teacher would only deepen his determination that he should not go back.
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) "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 not this holy vocation, but that, as ye tender the glory of God, the increase of Christ's kingdom, the edification of your brethren, and the comfort of me whom you understand well enough to be oppressed by the multitude of labours, that ye take upon you the public office and charge of preaching even as ye look to avoid God's heavy displeasure, and desire that He shall multiply His graces with you." Then turning to the congregation he said, "Was not this your charge to me?" They answered, "It was, and we approve it." The combined suddenness and solemnity of this appeal completely unmanned Knox. He burst into tears and hastened to his closet, where we may well believe that he sought light from God; and the result Was that he was led to take up that ministry which he laid down only with his life. Not from the impulse of caprice, or because he desired the position of a preacher, but because he could not otherwise meet the responsibility which God had laid upon him, did he enter upon that high and honourable vocation. He was to do a work for his countrymen not unlike that which Moses did for his kinsmen, and so like Moses he was called to it in the full maturity of his powers, and entered upon it with the conviction that God had given him his commission, and he dared not disobey.
Nor did he tarry long before he began to preach, for the call of Providence came almost simultaneously with that of the church. It happened just then that Mr. Rough was engaged in a controversy with a popish dean named Annand. For such a discussion Rough was but poorly furnished, since, as McCrie says, though he was sound in doctrine, his literary acquirements were only moderate. In his emergency he had been much assisted by Knox, who made such good use of the pen that he beat back his adversary from all his defences. As a last resort Annand took refuge in the authority of the Church, upon which Knox at once exclaimed, in the hearing of those who were present at the discussion, that a distinction must be drawn between the true spouse of Christ and the Church of Rome, and offered to prove by word or writing that the Papal Church had degenerated from that of primitive times more than the Jews who crucified the Saviour had fallen from the ordinances of Moses. On hearing this, the people alleged that they could not all read his writings, but could all listen to his preaching, and therefore insisted, in the name of God, that he would let them hear his proof of the assertion which he had made. Such an appeal was not to be resisted, and therefore on the very next Sunday Knox entered the pulpit, and preached (from the text Daniel vii. 24, 25) a sermon, in which, after having given the true marks of the Church, he went on to expose the corruptions of the Romish clergy in their lives, the erroneous doctrine taught by them, especially in the matter of justification, and the enslaving laws enjoined by them in regard to days, and meats, and marriage. In particular he inveighed against the blasphemies of popery. He identified the Papal Church with the Babylonian harlot in the book of the Revelation, and concluded by demanding the most thorough investigation of all the statements which he had made, and the most minute examination of the authorities whom he had cited. This discourse was listened to by a large assembly, among whom was John Major, his old Glasgow principal, and it produced a great effect upon all. Some said, "Others lopped off the branches of the papistry, but he strikes at the root to destroy the whole." Others predicted that he would meet the fate of Wishart, who had never spoken quite so plainly as Knox had done that day. The new archbishop of St. Andrews, not yet consecrated to his office, expostulated with the vicar-general of the diocese for allowing such heretical doctrines to be promulgated without opposition, and that led to the calling of a convention of the learned men of the abbey and the university, before which Rough and Knox were summoned to make answer to nine articles, involving heresies, which had been drawn from their sermons. But nothing more serious resulted from that meeting than a debate between Knox and a friar named Arbuckle, whose arguments Knox easily refuted, and that too with a considerable mixture of the grim humour which ever and anon laughs outright in the pages of his history. Clearly, therefore, it would be a perilous thing for the Church to let such a man do all the preaching to the people; and so orders were issued that each of the learned men in the abbey and university should preach in his own turn on the Sundays in the parish church. This deprived Knox of the opportunity of addressing the congregation on those days when the greatest numbers were in attendance; but he continued his ministry on the other days of the week, and that with such success that although it lasted in all at this time not more than three months, many of the inhabitants of the town renounced popery, and made confession of the Protestant faith by partaking of the Lord's Supper in the reformed manner, the first occasion on which the ordinance was publicly administered in Scotland after that fashion.
Thus the beginning of Knox's work marks a distinct stage in the history of the Scottish Reformation. At first, and under what has been called by Lorimer the Hamilton period, peculiar emphasis was laid upon the truths which were revived in the teaching of Luther; under the Wishart period the doctrine of the sacraments came into prominence, and then first the influence of Switzerland began to be felt by Scotland; but under Knox attention was directed especially to the nature and constitution of the church, and the first sermon which he preached, and of which we have given the barest outline, had already in it "the promise and the potency" of the great work which he was yet to accomplish for his native land.
