Employing an interdisciplinary methodology integrating biblical, historical, systematic, and practical theology, this research reestablishes the theological foundations of worship through the Psalms and David's tabernacle model, investigates the communal nature of worship from Old Testament sacrificial systems through New Testament ecclesiology, and conducts comparative case studies of the Taizé Community, Anglican liturgical tradition, and the Royal School of Church Music (RSCM). These three models, despite their diverse origins, converge on shared principles: God-centeredness, communal integrity, and a dynamic balance between tradition and renewal.

The study also addresses lessons from online worship during the COVID-19 pandemic. Practical proposals include Psalm-centered worship recovery, theological filtering of worship music, integrated traditional-contemporary worship models, restructuring for communal participation, and leadership education for worship renewal. The core contribution lies in diagnosing the Korean worship crisis as a theological identity crisis rather than a mere stylistic dispute, offering biblically grounded and actionable pathways for revitalization.
