The name of John McLeod Campbell (1800–1872) is well-known among historians of Scottish church history. A pastor who spent most of his life in Glasgow, Campbell is remembered best for his deposition from the Church of Scotland in 1831 because of the preaching of unlimited atonement and of assurance as belonging to the essence of faith. Among historians of doctrine, Campbell's notoriety stems from his later work, The Nature of the Atonement. The book aroused controversy from the moment of its publication. Among the highly original themes set forth by Campbell, one continues to stand out as the most perplexing and controversial: Campbell's teaching on Christ as providing a ‘perfect response’, a ‘perfect repentance’, a ‘perfect sorrow’ and a ‘perfect contrition’ before the judgment of the Father on the sins of humanity.
