Marrow Controversy
The Marrow Controversy was a theological dispute in the early 18th-century Church of Scotland, precipitated by the 1718 republication of Edward Fisher's The Marrow of Modern Divinity (1645), a treatise advocating a clear distinction between law and gospel, the universal offer of salvation by free grace, and assurance of faith not contingent on evidences of sanctification.[1][2] The book, reprinted by minister James Hog and endorsed by Thomas Boston of Ettrick, provoked opposition from kirk authorities who alleged it promoted antinomianism by diminishing the law's role in convicting sinners and guiding believers.[2][3] Proponents, dubbed the Marrow Brethren—including Boston, Ebenezer Erskine, and Robert Riccaltoun—contended that prevailing doctrines in the assembly veered toward legalism, erroneously tying gospel acceptance to preparatory repentance or moral preparation, thus obscuring justification by faith alone.[3][4] In 1719, the General Assembly's committee identified doctrinal errors in the text, leading to its formal condemnation in 1720, yet the debate exposed deeper tensions over neonomianism and the covenant of works' implications for assurance.[2][1] The controversy's ramifications extended to the 1733 Secession Church formation, underscoring fractures in Scottish Presbyterianism between grace-centered evangelism and conditionality in salvation.[3][4]
