That is the motto of Answers in Genesis:
When you start with ‘believing it’ as the first principle, you encourage groupthink. What one person thinks is what everyone else must think. We follow this by defense. Not examination. Not reformation. Not reforming or renewal. Only defense. This is the root of fundamentalism wherein there is no examination of the belief, only the requirement to believe it and then to defend it. As Peter Enns suggest for believers like Albert Mohler, theology should never be examined, only defended.
This is a pitiful excuse for ‘apologetics’ and indeed, a pitiful method of actual exegesis.
God help us never to be that locked into our own doctrines and beliefs that we never hear the Spirit calling….
