"the Christian movement at its inception was not just a way of life in the modern sense, but a way of life founded upon a message. It was based, not upon mere feeling, not upon a mere program of work, but upon an account of facts. In other words it was based upon doctrine...Paul was not interested merely in the ethical principles of Jesus; he was not interested merely in general principles of religion or of ethics. On the contrary, he was interested in the redeeming work of Christ and its effect upon us."
-J. Gresham Machen. Christianity and Liberalism. pg 21, 25
