Curriculum reform in Indonesia has repeatedly emphasized flexibility, deep learning, and student-centered instruction. Nevertheless, many reforms have not been translated effectively into classroom practice. Existing studies tend to focus on teacher competence and policy readiness, while the deeper dimension of teacher beliefs remains underexplored. This study aims to unpack how teacher beliefs shape responses to curriculum reform and to identify the belief-related factors that influence the success or failure of curriculum innovation. A qualitative descriptive design was employed using pre-Delphi reflective questionnaires and Focus Group Discussion data involving senior secondary school teachers and educational stakeholders. Data were analyzed thematically to identify recurring patterns of belief, challenge, and adaptation. The findings reveal that teacher beliefs constitute the most decisive factor in curriculum implementation. Three major themes emerged: (1) a persistent gap between curriculum policy and classroom practice, (2) the difficulty of transforming teachers’ mindsets from fixed to growth-oriented perspectives, and (3) the construction of an ideal teacher identity characterized by reflection, adaptability, collaboration, and moral commitment. More importantly, teachers viewed curriculum change not merely as a technical demand, but as a moral and spiritual responsibility. Curriculum reform will remain ineffective unless it addresses teachers’ internal beliefs. Sustainable transformation requires professional development that integrates cognitive, emotional, and spiritual dimensions of teaching.      

This article examines the pastoral phenomenon among the faithful, who firmly believe in the truth and infallibility of the Scriptures without feeling the need to interpret or explain the texts themselves. Based on limited interviews conducted, this study finds that this phenomenon does not arise from a lack of faith but rather from the Church’s teaching that emphasizes the authority of the Scriptures without allowing space for personal interpretation. The results of these interviews are combined with patristic sources and modern theological discussions to delve deeper into the integration of the truth of the Scriptures into the daily practice of the faithful. A tendency toward clerical interpretation has been found to hinder the sensus fidei, or the communal sense of faith, leading to an exaggerated fear of possibly misinterpreting the Scriptures. Therefore, an inclusive pastoral approach is needed, including through digital and catechetical media, to encourage the faithful to engage with the Scriptures within the bounds of ecclesiastical unity. This aims to ensure that the faith of the faithful is not only a matter of belief but is also practiced with true and comprehensive understanding.
