The intersection between Christian values and political governance reveals both challenges and benefits in shaping just societies Christianity’s relationship with political authority has long been contested, shaped by theological perspectives, historical experiences, and practical concerns. This paper examines the role and benefits of Christian involvement in politics, using Constantine the Great as a central case study. Findings show that the Constantine shift marked a transformative era in which Christianity moved from a marginalised, persecuted faith to a religion of imperial favour and influence. Through this development, Christians began to participate actively in governance, legislation, and public life. Critics argue that Constantine’s adoption of Christianity introduced compromises that diluted the Church’s spiritual purity, while supporters contend that his reign demonstrated the potential benefits of Christian engagement with political authority, including religious tolerance, social cohesion, and moral influence on statecraft. The study adopts critical analysis as methodology which will be used to analyse the historical, theological, and political dimensions of Constantine’s involvement in governance of his day. This will highlights the complex but fruitful relationship between Christianity and political power. Thus the stand of this research is that responsible Christian involvement in politics can contribute positively to societal order, ethical governance, and social justice when aligned with core biblical values. Drawing from Constantine’s example, the study provides insights into the enduring question of how Christians should engage political authority in diverse socio-political contexts.
