James Buchanan

Overview

James Buchanan (1804-1870) was a Scottish Presbyterian theologian who spent the last two decades of his teaching career at New College, Edinburgh, first as professor of apologetics and then, from 1847, as professor of systematic theology, succeeding Thomas Chalmers.¹ He is best known for The Doctrine of Justification (1867), an exposition of the doctrine’s biblical basis and post-Reformation history that grew out of lectures he delivered the previous year.¹

Life and Ministry

Buchanan was born in Paisley, Scotland, on April 14, 1804, and educated at Paisley Grammar School before studying at the Universities of Glasgow and Edinburgh.¹ Licensed to preach by the Presbytery of Paisley in 1826, he was ordained a Church of Scotland minister at Roslin in November 1827 and translated to North Leith Parish Church in September 1828.¹ In 1840 he was called to a second charge at St Giles Cathedral in Edinburgh.¹

At the Disruption of 1843, Buchanan left the established Church of Scotland for the newly formed Free Church of Scotland, becoming the first minister of the Free High Church of Edinburgh.¹ Two years later New College, the Free Church’s Edinburgh divinity hall, appointed him professor of apologetics, a post he combined from 1845 with the ministry of St Stephen’s Free Church, Stockbridge.¹ In 1847 he succeeded Thomas Chalmers in New College’s chair of systematic theology, a post he held until his retirement in 1868.¹ Princeton awarded him an honorary doctorate of divinity in 1844 and the University of Glasgow an honorary doctorate of laws in 1852.¹ He was married twice, to Elizabeth Cochrane, who died in 1832, and to Mary Morison, who survived him.¹ Buchanan died in Edinburgh on April 19, 1870, at the age of sixty-six.¹

Theological Contribution

Buchanan’s best-known work, The Doctrine of Justification: An Outline of Its History in the Church and of Its Exposition from Scripture, began as the inaugural Cunningham Lectures at New College in 1866 before its publication the following year.¹ The book divides into two parts, a historical survey of the doctrine’s development in the church followed by a biblical exposition of its scriptural basis.² Surveying the Council of Trent’s response to the Reformation, Buchanan judged that the Roman theologians gathered there had been

much perplexed in dealing with the subject. It was felt to be singularly important, as all the errors of Luther resolved themselves into his doctrine concerning it; and also singularly difficult, since Justification by faith was regarded by many as a doctrine which had never been thought of by any School-writer, and therefore never discussed or confuted before.³

He read Trent’s condemnations of the Reformation doctrine as more dogmatic than the council’s own positive statement of justification, taking that imbalance as evidence that the Reformers had introduced a clarity into the church’s teaching that Rome’s own theologians had not yet worked out for themselves.³

Two of the book’s lectures trace the seventeenth-century English dispute between neonomians, who treated the gospel as a milder law that faith and obedience together satisfy, and antinomians, who denied any continuing role for the law in the believer’s life; Herman Bavinck’s dogmatics directs readers to these lectures specifically for further information on that controversy.⁴ Within his biblical exposition, Buchanan also defended the Reformed teaching that Christ’s own obedience to the law, and not only his suffering, is imputed to the believer in justification, though he gave the point comparatively brief treatment.²

Historical Significance

Samuel Waldron’s dissertation on sola fide quotes Buchanan’s own assessment of the confusion at Trent as evidence for the Reformation’s contribution to the doctrine’s development.³ Micah McCormick’s study of the active obedience of Christ cites the specific pages of Buchanan’s book that take up the doctrine.² Herman Bavinck’s Reformed Dogmatics points readers to Buchanan’s own lectures 6 and 7 for further information on the neonomian and antinomian controversy.⁴
