Robert Bruce (1554 – 27 July 1631) was Moderator of the General Assembly of the Church of Scotland which was called on 6 February 1588 to prepare defences against a possible invasion by the Spanish Armada. King James VI was so sensible of the valuable services of the church in preserving public tranquillity, during his absence in Norway (part of Denmark at the time) on the occasion of his marriage, that in his letters to Bruce he declared that he was "worth the quarter of his kingdom." John Livingstone, the preacher at the Kirk of Shotts revival, said of Bruce "in my opinion never man spake with greater power since the apostles' dayes".
