John Knox

According to Rampant Scotland, on July 7, 1559, John Knox became the first Protestant minister to be appointed in Edinburgh.  Sir Walter Scott mentions this revolutionary figure, and his influence on Scottish history, several times in his "Tales of a Grandfather":

'...The prevalence of the Protestant doctrines in Scotland strengthened the Scottish nobles in their disposition to make a stand against the Queen Regent's desire to augment her power. Many great nobles, and a still greater portion of the smaller barons, had embraced the Reformed opinions; and the preaching of John Knox, a man of great courage, real, and talents, made converts daily from the Catholic faith....'

John Calvin

"...Among the attentive group which I now saw, might be distinguished various expressions similar to those of the audience in the famous cartoon of Paul preaching at Athens. Here sat a zealous and intelligent Calvinist, with brows bent just as much as to indicate profound attention ; lips slightly compressed; eyes fixed on the minister with an expression of decent pride, as if sharing the triumph of his argument; the forefinger of the right hand touching successively those of the left, as the preacher, from argument to argument, ascended towards his conclusion. Another, with fiercer and sterner look, intimated at once his contempt of all who doubted the creed of his pastor, and his joy at the appropriate punishment denounced against them. A third, perhaps belonging to a different congregation, and present only by accident or curiosity, had the appearance of internally impeaching some link of the reasoning; and you might plainly read, in the slight motion of his head, his doubts as to the soundness of the preacher's argument. The greater part listened with a calm, satisfied countenance, expressive of a conscious merit in being present, and in listening to such an ingenious discourse, although perhaps unable entirely to comprehend it..."

Walter Scott's description of the Calvinist attending kirk services appears in "Rob Roy".  John Calvin was the son of a cooper, who was supported in his schooling by a wealthy family, attending the University of Paris.  Calvin met Wolmar the Reformer while in Bruges, who inspired him toward Protestantism.  Calvin influenced Scottish religious understanding, as represented in Presbyterianism, through John Knox, who studied under Calvin in Geneva.  Calvin died on May 27, 1564, at age 55.
