Is Behavior Based on Reason, or Tradition? And Is Belief Based on Reason or Tradition?

I wrote a post a few days ago about belonging was the ideal for faith, as it affirm all people as made in God's image and affims a humanitarian view of religion. But, as my thinking has "matured" these past few days, I understand they way I categorized belief and behavior as only one way of understanding; where belief was based on tradition and behavior was based on reason.

This is true if one wants to believe that all belief systems are limited ways to understand "god" and therefore, all relgions are man's attempt to interpret "god". The history of traditions area would affirm this way of thinking.

But, can't belief also be based on reason? Reason is useful in any attempt within a particular tradition to understand "faith". This way of thinking would be affirmed by the philosophy of traditions approach.

Behavior can be viewed as cultural (tradition) or theological (reason). If one undestands the culture's tradition and the way that culture defines worship, then behavior reinforces the tradition's understanding of "truth". This way of thinking is understood by the psychology of religion approach...

So, whether one understands behavior or belief in a cultural or reasoned way, both are "ways of life", a "way of understanding" and a "cultural framework".
