John Kennedy (1819-1884) of Dingwall, was a Scottish preacher and theologian. He was also a staunch defender of the Reformed Faith who was, as his friend Charles Spurgeon described him, true as steel and firm as a rock.
He was educated in the parish school of Killearnan, and in 1836 went to Aberdeen University. He graduated M.A. at King's College in 1840, and in the same year entered the theological hall of the established church in Scotland. Kennedy was licensed by the established church in September 1843, but joined the free church and was inducted into a free church newly formed at Dingwall, Rosshire, February 1844. He was pastor of Dingwall Free Church congregation from 1844 until his death in 1884 at the age of 65.
Kennedy was a stalwart opponent of the drift in Scottish Presbyterianism away from the Westminster Confession, allying himself with Hugh Martin and James Begg to resist erosion of the doctrine of the particular design in Christ's atoning work, definite atonement, and to contend for the propriety of a cooperative association of church and state to promote the true religion.
