There are roughly two parts to Christian fundamentalism: a commitment to the fundamental truths of the Bible, and a strong impulse to separate from the surrounding culture. Aaron and Chuck talk about what’s biblical and what’s unbiblical with this definition of Christianity, and discuss Aaron’s background in a particular version of American Christian fundamentalism.
The difference between biblical Christianity and fundamentalist Christianity is not in the details of what is believed, but in biblical Christianity’s insistence that Jesus calls the Christian Church to love the world by living in it, living with it, communicating with it, speaking the truth of the gospel in language that is understandable, etc.
