John Knox (c. 1514 – 24 November 1572) was a Scottish minister, theologian, and writer, who is considered the father of the Presbyterian Church of Scotland. Knox's most significant contribution to Scottish religious reform is his work on 'The Scots Confession of Faith' (1560), which reflects the Calvinist doctrine that was influential during the Protestant Reformation. It was ratified by the Parliament of Scotland and became the doctrinal standard for the church. Known for his robust preaching and unwavering commitment to reformed ecclesiology, Knox's influence extended beyond theology into the political sphere, advocating for the overthrow of the Roman Catholic Church and the Papacy in Scotland. His literary style was direct and fervent, mirroring his passionate religious convictions. Knox's other major works include 'The First Blast of the Trumpet Against the Monstrous Regiment of Women' (1558) and his 'History of the Reformation in Scotland'. Despite his controversial stance against female monarchs, Knox's role as a leader of the Scottish Reformation remains his enduring legacy, shaping the Presbyterian faith and contributing to the formation of a distinctly Scottish Protestant identity.
