Secular humanism has taken the world by storm – including the realm of African politics. Believing that religion is irrelevant, humanism asserts that men and women need no divine help in knowing what is right or wrong, valid or invalid, good or bad, as they are mature moral agents in their own rights. Integrity in Nigerian Politics challenges this assertion, providing an introduction to Christian political ethics and offering a powerful argument for its relevance in the complex moral terrain of today’s political affairs. Rooted specifically in Nigeria’s political history, and the social, religious, and economic challenges it has faced, this study explores the role of integrity in practical politics and the implications of its neglect. Establishing that it is the character of God that is the foundation for successful governance, Dr Aghawenu demonstrates that it is ineffective, impractical, and ultimately dangerous to ignore the ethical insights Christianity has to offer the political realm. This important work challenges the church to overcome the sacred-secular divide that so often permeates its public engagement and to recognize that it has what it needs to transform the nature of democratic politics in Nigeria, in Africa, and throughout the world.
