Robert S. Candlish was an evangelical minister in Edinburgh. He was a key figure in the 1843 Disruption in the Church of Scotland that led to the founding of the Free Church of Scotland. He was a Calvinist who published many works of preaching, systematic theology (esp. on the atonement), and biblical exposition (Genesis, Ephesians, & 1 John). His biblical expositions are highly recommended.
