There is a diversity of religions in Lesotho with Christianity being a dominant religion. The unique religious landscape along with pressing social justice challenges provide a backdrop for the study that explores an innovative approach to domesticating Christianity within the secondary school education system in Lesotho. The primary goal of this study is to foster social justice competences by adapting Christianity to address prevalent societal issues unique to Lesotho. Instead of teaching orthodox Christianity, the study suggests a process of domestication, promoting enduring competences that are relevant to the specific challenges in Lesotho. The study recommends an interfaith approach that accommodates all students while retaining their convictions. The study advocates for teacher training, community engagement, and a focus on universal principles of love, compassion, and justice, rather than specific Christian doctrine, to empower students to address real-world social issues while preserving religious and cultural diversity. In addition to presenting the proposed approach, the study highlights key considerations, including inclusivity and consultation with relevant stakeholders. These elements are essential to ensure the success of this innovative approach, which aims to harmoniously align Christianity with Lesotho's unique cultural and religious context while cultivating social justice competences.
