The leaders in Group B are the ones that seem to question the most answers. The members in Group C, however, are the ones that take all of Group B's questions and all of Group A's answers and make their own conclusions. The leaders in Group C are often revered by both Group A and Group B. This group is where the world's greatest thinkers emerge.
Members of Group C have taken the best from both groups and have taken it a step further. Because of this, they are not afraid of either Group A or Group B. They will often identify themselves with both and can tell you what Group A's answers really mean (which most members of Group A won't even be able to do) and they can provide a reasonable answer to most all of Group B's questions (which usually leaves them struggling to think of more questions). If you were to ask a member of Group C what they believe, they will probably give you an intelligent answer that anyone could dissect and find to be valid.
Of these three groups, Group C is the group that has the ability to change the world. The other groups seem to only go as far as being known by the world (which is the only goal of some of it's members). Members of Group C are the ones that know the path of attaining the true knowledge that the world has to offer.
As for Group A, they already have all their answers, so the completely miss the knowledge that comes from the path of questioning. They have cut out the middle and gone straight to the end. It's like knowing that 4 is the answer to 2 +2, but never understanding the concept of addition. So if asked what x represents in 2 + x = 4, they will often have no idea and refuse to answer by suppressing such questions.
As for Group B, they will be slightly beyond Group A in that they welcome questions, but they never gain the knowledge from those questions because they never seek out the answers. So am I alluding that Group C has all the answers? No. In fact, Group C probably won't have any answers.
This fits into faith in that we are all faced with faith based questions and how we decide to deal with those questions ultimately determines how we walk in our faith. If you are in Group A, you will settle upon traditional answers. This is not to say that traditional answers are wrong, but it is to say that they are someone else's answers and not yours. This route keeps you stagnant in faith. It's in finding answers that questioning stops.
If questioning stops, the flow of knowledge stops with it. If your flow of knowledge stops, it is impossible to learn more about your faith, which makes it impossible to move forward in it. If you are in Group B, you will start to question your faith, but then get lost in the questions.
This means that you feel as if you are moving forward becomes you have found a path, but instead of following that path and reaping it's knowledge, you look for another path instead. Your time is wasted looking for all the different paths you can find while never following a single one all the way to the end. If you are in Group C, then you are not afraid to follow any question all the way through.
In doing so you are lead down many paths, which adds to your experience in many different things. You will also come to find out that ultimately there is one answer and that no matter which path you take, it always circles around to the same thing. This will go on to prove that if there is an ultimate truth, then no line of questioning can ever prove it wrong. When it comes to questioning, where do you stand?
