Edward Irving (1792-1834) was a dynamic and controversial Scottish preacher. After serving as assistant to Thomas Chalmers in Glasgow (1819-22), Irving was called to the Caledonian Church, London, where his speaking brought him much attention. As his preaching began to emphasize the supernatural and the imminence of the second coming of Christ, criticism arose, especially over his views on the human nature of Christ. In 1832 he was debarred from the Regent Square Church; in 1833 he was deposed from the ministry of the Church of Scotland.
Irving had, from 1826, been meeting with a group gathered together by Henry Drummond to study the prophecies of the Scriptures. From this "school of the prophets" was developed the Catholic Apostolic Church, of which Irving was a bishop.
