Questioning the teaching helps to lead to further study and exploration of life, which leads to firmer and stronger faith. In Buddhism faith is actually enhanced by questions and practicing. Faith is one part questioning and another part practicing and applying. I personally believe that we should flee from anyone or any teaching that tries to lie outside the realm of questions. Refusing to answer questions or implying that questioning is wrong or unfaithful should be an automatic warning that something just isn’t quite right.
