This journal aims to explore the contextualization of theology in the development of the church in East Asia, focusing on the interaction between the teachings of the gospel and local traditional belief systems. The approach used in this study is a qualitative method. The findings of this study show that churches in East Asia attempt to integrate fundamental Christian teachings and adapt to local cultural needs and customs. The research found that despite efforts to create worship that is more relevant to local cultures, churches are still careful not to mix Christian teachings with traditions that could undermine the core teachings of the faith. In addition, the research also found that there is a difficulty in finding a balance between liturgical innovation and maintaining the holiness of Christian teachings. Too much adaptation to local cultural elements can lead to a loss of authentic Christian identity, while too little adaptation can make Christianity difficult to be accepted by society. To deal with this kind of conflict, churches in East Asia have endeavored to develop theologies rooted in their local traditions. In this way, churches in East Asia seek to create a deeper understanding of how the gospel can interact with the social, cultural and spiritual needs of local communities. One of the important findings of this study is also the importance of active congregational participation in the contextualization process. This congregational participation and diologetics help local churches to be more sensitive to existing social and cultural dynamics, as well as make a greater contribution in determining relevant forms of worship and teaching. This includes the avoidance of practices that could lead to syncretism, i.e. the mixing of Christian teachings with traditional elements that are contrary to the Christian faith.

This article examines pastoral counseling strategies for congregants whose Christian faith is weakened by sustained exposure to secular digital content. The problem is not framed as a deterministic claim that digital media directly destroys faith, but as a practical-theological concern: algorithmic personalization, secular moral imaginaries, online doubt communities, entertainment habits, and fragmented attention can reshape belief, practice, belonging, and trust in church authority. The study aims to construct a counseling model that is theologically responsible, psychologically informed, and pastorally usable in local churches. Using a conceptual qualitative design, the article synthesizes literature from digital religion studies, mediatization theory, adolescent and emerging-adult religiosity, media psychology, religious coping, and spiritually integrated counseling. The analysis identifies three main findings. First, faith degradation should be diagnosed as a layered process involving cognitive doubt, affective dryness, moral dissonance, ritual discontinuity, and communal displacement. Second, pastoral counseling must move beyond prohibition toward discerning digital habits, rebuilding spiritual attention, and restoring relational trust. Third, an integrated strategy is proposed: assessment of digital-spiritual formation, narrative and theological reconstruction, communal re-embedding, and digital rule-of-life practices. The article concludes that pastoral counseling in the digital age should function as a ministry of interpretive accompaniment rather than merely corrective instruction.

This study focuses on the concept of salvation by grace as taught in Romans 3:23-26 and its relevance to the understanding of the GKPPD congregation today. Through a literature review with a theological approach, it was found that the doctrine of salvation by grace is the core of Christian teaching. In this passage, the Apostle Paul explains that all humans have sinned and fallen short of the glory of God (Romans 3:23). However, salvation is given through redemption in Christ Jesus, not as a result of human effort, but as a gift of God alone (Romans 3:24). Salvation is given through faith in the blood of Christ which redeems and takes away sin (Romans 3:25). In the context of the congregation today, the understanding of salvation by grace remains relevant. Many GKPPD congregations are still trapped in trying to obtain salvation through or obedience to the law, even though Romans 3:23-26 emphasizes the importance of faith in Christ's redemptive work. This study highlights that teaching about God's grace should foster a sense of gratitude, humility, and commitment to living in faith, not in fear or legalism. This study confirms that the concept of salvation through grace is the center of Christian faith teachings that need to continue to be lived and conveyed in the lives of the GKPPD congregation today and increase theological knowledge about the concept of salvation and can be a reference for theology students and reading materials in the IAKN Tarutung library.
