The intersection of theistic religion and politics sparks continued controversy, particularly when addressing complex social issues like immigration. When religious ideologies influence political decisions, they can lead to policies that are less informed by empirical evidence and more driven by doctrinal beliefs. The consequences are not only detrimental to the integrity of policymaking but also to the well-being of communities affected by such policies. Critical examination of the impacts of theistic religion on political discourse and immigration is necessary to advocate for improved, evidence-based approaches to policymaking. Detriments of Theistic Religion in Politics and Its Effect on the Immigration Problem explores the effects of religious influences in government policies related to immigration. Aspects of theology, ethics, and morality related to policy and law creation are explored, along with effective solutions to solve issues of immigration in the Unites States. This book covers topics such as theology, ethics and morality, and political science, and is a useful resource for politicians, policymakers, government officials, economists, religious organizations, business owners, academicians, researchers, and scientists.
