Nicholas Taleb helps us understand why tradition is helpful::
Consider the role of heuristic (rule-of-thumb) knowledge embedded in traditions. Simply, just as evolution operates on individuals, so does it act on these tacit, unexplainable rules of thumb transmitted through generations— what Karl Popper has called evolutionary epistemology. But let me change Popper’s idea ever so slightly (actually quite a bit): my take is that this evolution is not a competition between ideas, but between humans and systems based on such ideas. An idea does not survive because it is better than the competition, but rather because the person who holds it has survived! Accordingly, wisdom you learn from your grandmother should be vastly superior (empirically, hence scientifically) to what you get from a class in business school (and, of course, considerably cheaper). My sadness is that we have been moving farther and farther away from grandmothers.

Now, in Christianity tradition includes, but is not limited to Scripture. The idea is that Scripture is the measuring rod against which other traditions are judged. Scripture takes pride of place whether the church is examining practices, beliefs, or ways of speaking about God. But this does not mean that traditions are always wrong.
Socrates is right that everything should be questions. Postmodernists are wrong that they should be rejected.
