Pedagogical Professionalism and Spiritual Identity Formation: Interpreting Exodus 19:4 within Christian Religious Education at SMA Swasta Masehi GBKP Berastagi

Abstract

This study investigates the relationship between pedagogical professionalism and students’ spiritual identity formation within the context of Christian Religious Education at SMA Swasta Masehi GBKP Berastagi. Grounded in a theological interpretation of Book of Exodus 19:4, which portrays divine initiative as the foundation of covenantal identity, the research conceptualizes teacher professionalism as a formative agent in shaping students’ spiritual self-understanding. Pedagogical professionalism was operationalized into four dimensions: theological competence, pedagogical competence, relational-ethical integrity, and vocational commitment. Spiritual identity formation was measured through indicators of divine belonging, spiritual self-awareness, moral responsibility, and communal faith participation. The study employed a quantitative correlational design involving 240 students selected through proportionate stratified random sampling from a population of 600 Christian students. Data were collected using validated Likert-scale questionnaires and analyzed using descriptive statistics, Pearson’s Product-Moment Correlation, and simple linear regression. The results revealed a strong positive correlation between pedagogical professionalism and spiritual identity formation (r = 0.71, p < 0.001). Regression analysis indicated that pedagogical professionalism significantly predicted students’ spiritual identity, accounting for 50.4% of the variance (R² = 0.504). The findings suggest that professional competence in Christian education extends beyond instructional technique to encompass theological coherence, relational authenticity, and vocational dedication. Interpreted through the covenantal imagery of Exodus 19:4, pedagogical professionalism functions as a mediating structure through which students internalize spiritual identity. This study contributes empirically to the discourse on holistic Christian education by demonstrating that teacher professionalism plays a decisive role in shaping students’ spiritual formation within faith-based schooling contexts
