John Knox was first called to the Protestant ministry at St. Andrews, which was throughout his life intimately associated with the Reformer's career. There appears to have been no regular ordination. Of course, he had been already ordained as a priest in the Church of Rome. A detailed account of the whole proceedings connected with his call to the ministry, together with a report of the first sermon he delivered in St. Andrews, will be found in Konx’s most famous book, “The History of the Reformation in Scotland”.
