George Gillespie
1613–1648
Youngest divine at Westminster; demolished the Erastian case in *Aaron’s Rod Blossoming*.
Biography
Only 30 when he arrived in London, Gillespie was the youngest commissioner and quickly emerged as the sharpest debater. His famous extempore reply to Selden on the keys (1645) became Westminster lore; *Aaron's Rod Blossoming* (1646) is the canonical Reformed refutation of Erastianism. He returned to Scotland exhausted, was elected Moderator of the General Assembly in 1648, and died of consumption later that year aged only 35.

Scottish Commissioner
Under the Solemn League and Covenant (1643) the Church of Scotland sent commissioners — ministers and ruling elders — to sit with the Assembly. They had voice in debate but no formal vote, yet their influence on the Standards, especially on worship and presbyterian polity, was decisive. Alexander Henderson, Samuel Rutherford, George Gillespie, and Robert Baillie were the leading ministerial commissioners.
