Here's another response to a student from the first on-line Christian Beliefs course from June 2010. The question was about whether it is okay to just accept what has been traditional taught and believed. Here is my response:
About your question of whether we should then question all the beliefs we have always known and accepted as true. I'm not sure we need to go back and look at all of our family's or church's beliefs and question them without a good reason to do so. On the other hand, as questions arise, especially as we interact with people from other Christian traditions or other belief systems, we should not just accept them (or our positions) hands down, but learn to listen carefully, ask questions, not get too quickly scared of uncertainty, and not settle for easy answers. God will be faithful and walk with us as we learn more about Him (and what we believe or need to believe about Him.
