Professionalism in Faith-Based Teaching: Cultivating Integrity through Genesis 39:21–23 in SDS Methodist-12 Medan

Abstract

This study explores the role of professionalism in faith-based teaching in cultivating student integrity through the biblical narrative of Genesis 39:21-23. Situated within the context of SDS Methodist-12 Medan, the research examines how Christian teachers integrate scriptural values into pedagogical practice to support character formation. Employing a Systematic Literature Review (SLR) method, the study synthesizes recent scholarly works on teacher professionalism, faith-based education, and integrity development to construct a conceptual understanding of how moral values are effectively transmitted in classroom settings. The findings reveal that professionalism in Christian education encompasses not only pedagogical competence but also moral authenticity and spiritual consistency. Teachers who demonstrate coherence between belief and action create relational trust that enhances students’ receptivity to value-based learning. The story of Joseph in Genesis 39:21-23 serves as a theological framework for understanding integrity as steadfast faithfulness in challenging circumstances. When integrated through dialogical and reflective teaching strategies, this narrative enables students to connect biblical principles with real-life ethical decision-making. The review further indicates that integrity formation is strengthened through experiential learning, reflective discussion, and a supportive institutional culture. Professional teachers function as moral models whose conduct becomes a living curriculum that shapes student character. In addition, school environments that reinforce shared ethical commitments amplify the impact of integrity-centered teaching. The study concludes that professionalism in faith-based teaching is a holistic practice that integrates competence, character, and calling. By embodying and contextualizing biblical values, Christian educators play a critical role in nurturing students who are intellectually capable, spiritually grounded, and ethically responsible.
