Christian Sexual Ethics: An Exegetical Study of 1 Corinthians 6:12-18

Abstract

Sexual immorality remains a serious and persistent challenge in the Church of Uganda, undermining its moral authority and public witness. Despite Uganda’s overwhelming Christian majority with approximately 85 percent of the population identifying as Christian (UBOS, 2014), the country records one of the highest teenage pregnancy rates in East Africa (UBOS & ICF International, 2018), alongside documented cases of moral failure even among church leaders. Yet empirical studies demonstrate that the Church’s moral influence on sexual behaviour is both real and significant, though it depends heavily on the theological depth and pastoral quality of its teaching. It is this need that the present study seeks to address through an exegetical investigation of 1 Corinthians 6:12-18. Employing a qualitative, library-based, historical-grammatical method, the study examines the Greek text within its historical, literary, and theological context before drawing pastoral conclusions for the Ugandan church. It is guided by two questions: what are the key theological principles regarding the body and sexual ethics in 1 Corinthians 6:12-18, and what practical strategies can promote sexual holiness in the Church of Uganda? The exegetical analysis identifies four theological principles in Paul’s argument: a resurrection-grounded theology of the body; a reframing of Christian freedom as communal service and Spirit-empowered self-mastery; the one-flesh theology of sexual union grounded in Genesis 2:24; and the urgent, continuing command to flee sexual immorality as an expression of union with Christ. Together these do not form a list of prohibitions but a compelling vision of Christian identity that renders sexual immorality theologically incompatible with belonging to Christ. The study proposes four practical strategies for fostering sexual holiness: theologically grounded preaching; discipleship and catechesis that treat sexual ethics as central to Christian identity; theologically rich premarital ministry; and communal accountability structures that hold truth and grace together. The study concludes that Paul’s word to the Corinthians remains a living and directly relevant word for the Church of Uganda today.
