Gillespie is best known for his two major works on worship and the relationship between church and state, A Dispute Against the English Popish Ceremonies (1637) and Aaron’s Rod Blossoming (1646). The first is in print in a recent critical edition, while the latter, Gillespie’s largest single work, and a masterpiece in Scottish ecclesiastical theology (James Walker), awaits such careful treatment. However, in addition to his two main works, Gillespie’s shorter writings and sermons amount to material twenty percent larger than the two larger works combined and includes his more succinct and some of his best writing. This three-volume set will present all of Gillespie’s known shorter works, carefully edited for the most accurate texts, including newly transcribed manuscript material and writings not included in the 19th century edition of his works.
