In 1923, J. Gresham Machen published his book, Christianity and Liberalism, in response to the cultural challenges of his day. Exactly 100 years later, his words ring out as powerfully as ever as he shows that progressive Christianity is not Christianity at all. This seminar will explore the enduring effects of Machen’s life and insights to help our church understand why liberalism still remains a threat to true Christianity and how we ought to respond.
