The Marrow Brethren, also called Marrowmen, were a group inside Presbyterianism.
[1] The leading figures of the Marrow Brethren included Thomas Boston, Robert Riccaltoun, James Hog, John Williamson, James Bathgate, and Ebenezer Erskine along with the author of the Marrow, Edward Fisher.
[8] The Marrow Brethren, though rejecting universal atonement, held to a strong view of common grace and that in some way God desires the salvation of all.
[10][11] They saw high Calvinism as "misguided" and sought to defend the free offer of the gospel against the Assembly.
[19] R. Scott Clark, a professor in Westminster Seminary California has defended the Marrow Brethren, saying: "The Marrow of Modern Divinity was regarded by the orthodox Reformed, in the 17th century, as a good summary of the orthodox view of law and gospel, justification, sanctification, and the third (normative) use of the law in the life of the Christian.
