Do Christians have to change their message to meet the needs of today's world? This question is as pressing for us as it was for J. Gresham Machen in 1923. With all the modern advancements of the early twentieth century, people wondered about the relevance of the church. Many church leaders set aside foundational Christian truths to create a more socially acceptable faith. This crisis drove Machen to draw a line in the sand with his classic book Christianity and Liberalism. In this teaching series, Dr. Stephen Nichols tells Machen's story and the timeless message of his book. There is only one true, uncompromising Christian faith, and it alone provides the ultimate answers to our world's problems.
