James Henley Thornwell - Antinomianism (1840) . . . Thornwell was one of the most influential theologians in the 19th century American Presbyterian Church. This little piece was an appendix to a reprint of Robert Traill's classic work on justification, which Thornwell published as a tract. In it, Thornwell shows how the gospel is opposed to both legalism and lawlessness, and how justification and sanctification are linked together in the plan of salvation.
