Black and White Morality

Problem context
Every person and society deals with the issue of morality.  Morality seems to be an intrinsic part of humanity, and we can see similarities across many different civilizations.  If there is one thing that can be said for morality, is that it is never stright forward.  There are always extenuating circumstances, interpersonal contexts, etc. that affect what we would consider right and wrong.  The problem is that in an attempt to make moral decisions easier, we sometimes resort to making black and white statements about right and wrong.  While these can make instantaneous decisions easier, it would seem they sometimes lead to a decrease in morality.

Behavior over time
At a hypothetical church, the current pastor has establashed a reputation for being conservative.  He is a "fire and brimstone" preacher that has instilled a healthy fear of damnation into his congregation, and has a knack for making things black and white.  As he ages, a new pastor is being brough in to take his place.  In an effort to be the most effective leader possable, the new pastor is evaluating how he wants to deal with morality in the congregation. 

Policies now in place or under consideration
The current policy has been to make morality black and white to ensure the congretion stays on the straight and narrow.  Although the membership numbers are good, there seems to be a waning percentage of youth in the congregation.  The new pastor is considering how to manage the morality of the congregation.

Issues and concerns with the current situation or policies
Although people seem to live essentally moral lives, the new pastor wonders if the existing black and white view is alienating some of the more "open minded" youth.  He wonders if the lack of middle ground or the ability to deal with "grey areas" is affecting the membership numbers.  He is also concerned that while the congregation is living morally, they may not have the mental maturity to deal with tough or complex issues due to the dictation of morals.

Study purpose and questions to be addressed
The new pastor, being the savy systems modeler that he is, puts together a model to study the situation.  Specificly, he aims to determine if the black and white stance reduces membership, affects the percentage of "moral decisions", and affects the congregation's ability to deal with "grey areas".
