John Duncan (theologian)

The Rev Prof John Duncan (1796 – 26 February 1870), also known as 'Rabbi' Duncan, was a minister of the Free Church of Scotland, a missionary to the Jews in Hungary, and Professor of Hebrew and Oriental Languages at New College, Edinburgh. He is best remembered for his aphorisms.

Duncan was born in Gilcomston, Aberdeen, the son of a shoemaker. He studied at Marischal College in the University of Aberdeen and obtained an MA in 1814. Duncan embarked upon theological study while still an atheist, first through the Anti-burgher Secession Church and then the Established Church. He completed his studies in 1821 and subsequently became a theist, but according to his later testimony was not yet converted when he was licensed to preach in 1825. Duncan was converted in 1826 through the ministry of César Malan, and in 1830 commenced ministry at Persie in Perthshire. The following year he moved to Glasgow, and was finally ordained as the minister of Milton parish church on 28 April 1836.

On the occurrence of a vacancy in the chair of oriental languages in the University of Glasgow, he offered himself as a candidate, stating in his application that he knew Hebrew, Syriac, Arabic, Persian, Sanscrit, Bengali, Hindostani, and Mahratti; while in Hebrew literature he professed everything, including grammarians, commentators, law books, controversial books, and books of ecclesiastical scholastics, and of belles-lettres. His application failed, but his college gave him the degree of LL.D. in 1840.
