Final answer:
Religion continues to play a role in reinforcing or maintaining political authority in the 21st century, through both state religion arrangements and influencing political views of individuals.
Step-by-step explanation:
In the 21st century, religion continues to play a role in reinforcing or maintaining political authority in various ways. In some countries, such as Iran, religious leaders head the political structure, while in others there is an explicit separation between religion and state. However, even in secular states like the United States, religious institutions receive favors from the government, such as tax-exempt status and access to resources.
Religion can also influence political views and actions of individuals. When people attend religious ceremonies, they are socialized to adopt beliefs that can affect their political stance on issues like abortion, euthanasia, social services, and military involvement. Additionally, political candidates often speak at religious institutions to appeal to like-minded voters.
Overall, the extent to which religion reinforces or maintains political authority in the 21st century varies depending on the country and the relationship between religion and state.
