This post is a crash-course in the decline of the Christian church since the late 19th century. The purpose herein is to help you assess the quality of your own faith as you come understand the unbiblical impact of Christian Liberalism. The first two videos surround a figure of the Presbyterian church in the early 20th century, J Gresham Machen. [Although Machen was a Presbyterian, his fight against the unbiblical movement of Christian liberalism is relevant to the whole of Christianity.] Two posts from this blog are linked because they provide necessary information about unbiblical evangelism and C H Spurgeon’s fight against liberalism, narrated by John MacArthur.
