With the ascendency of Protestantism in Scotland, a revolutionary Parliament was convened at Edinburgh, 1560, and commissioned John Knox to compile a new creed. Knox based his work on the Swiss Confessions. Known as the "Scottish Confession" it was ratified by Parliament and imposed as the religion of Scotland. It is of a Calvinistic nature, and remained until superseded by the Westminster Confession. James VI, 1581, commissioned James Craig to draw up a condemnation of papistry. Known as the "King's Confession," or the "Scotica Secunda," later as the "National Covenant," it endorses the Confession of 1560 and proceeds with a vituperation of Catholicity. It remained for generations favored by the Scots.
