Christian realism is a theological perspective that emphasizes the importance of understanding human nature and society through a realistic lens. It acknowledges the presence of sin and moral ambiguity in the world, advocating for a pragmatic approach to ethics and politics. This viewpoint often draws on the teachings of Reinhold Niebuhr, who argued that idealism alone is insufficient for addressing complex social issues. The core of Christian realism lies in the belief that faith should inform action in the world, while also recognizing the limitations of human efforts. It encourages believers to engage with societal problems, promoting justice and compassion while remaining aware of the inherent flaws in human institutions.
