How does the struggle between religious and secular authority affect society

Both religious and secular authorities bear a great importance in most people's lives. On the one hand, the moral and spiritual concerns that people feel (this is, a number of things than cannot be grasped by the five senses) are addressed by religion, which provides guidance and lessens the sense of uncertainty (Will I have a job tomorrow? Will my family be all right? Will my heath remain well for a long time?) resulting from the random nature of life events. On the other hand, secular authorities take care of concrete issues in the lives of people within the community by guaranteeing solutions to issues such as security, public health, education, public works, etc.

When secular and religious authorities agree over each other's duties and privileges, they bring about a high degree of well-being and prosperity for a community or even a nation. However, when they struggle to overstep the boundaries of the other's prerogatives, a likely violent conflict breaks out, and each side tries to gain the favor of as many people in the community to support their cause. This, in turn, weakens and damages the social fabric as its gets family members opposing other family members by taking sides with the secular cause, and the same goes for friends, neighbors, co-workers, etc. In summary, communities and nations become divided into two opposing groups supporting either the religious or the secular causes, which may lead to extreme violence and mistrust for the people defending the opposite cause lasting for eve a long time after the conflict has ended.
