This post contains two short videos about J Gresham Machen; the first is on his book Christianity and Liberalism. Therein, Stephen Nichols explains the controversy which led Machen to write his book. In the course of his explanation, Nichols provided basic teaching on modernism, liberalism, the Scopes monkey trial, and Christian fundamentalism…. If you know nothing of these things, you should hear this video because it will give you insight into origins of current struggles in the church. The second video, 7-minutes, is an answer to a question submitted to Ligonier Ministries. This video is also on Machen but is more of an overview and covers different things.
