However, there are few pure religious or political systems as set out above.
Many religions borrow from political methods to foster and maintain belief and behavior.
Likewise, many political systems borrow from religious methods to encourage belief systems that bring about proper inter-personal behavior. Oddly, the first examples that come to mind of each of these crossovers are totalitarian. Consider the Roman Catholic church's former inquisitions and other attacks against perceived heresy. Consider the modern example of Arab nations freely mixing religion and politics to enforce belief and behavior. On a lesser scale there are more humane examples.
