John Gerstner was the mentor of the late R C Sproul, in case you’ve never heard of him. I excerpted a 7-minute, 35-second portion from one of Gerstner’s teaching videos on the WCF. He was reading and explaining the chapters 6-8. Therein, he made a statement that the Westminster Divines would have opposed ‘modern Dispensationalism.’ He went on to explain that salvation, since the fall, has only been by God’s grace through Christ’s atoning work, noting that this biblical view is not held by Dispensationalists.
