The thrust of this interdisciplinary study is the theological examination of megachurches’ original contemporary congregational songs (CCS). This study aims to analyse and compare the sung theology of New Creation Church, Singapore (NCC) and Hillsong Church, Australia (Hillsong), specifically focusing on their original songs’ alignment with the fivefold Pentecostal theology. Employing a fivefold full gospel framework and utilising textual analysis, the research systematically evaluates core Pentecostal tenets in the CCS. The primary goal is to scrutinise NCC’s sung theology, while the secondary objective is to explore similarities and differences in the Christocentric theology of both churches, emphasising key aspects such as salvation, sanctification, the Holy Spirit’s baptism, healing, and the Second Coming of Christ. Examining a dataset of twenty-five original songs from each megachurch spanning 2014 to 2020, the study employs textual analysis to compare the lyrical content and theological themes. It also highlights parallels and distinctions in the sung theology of these geographically separated churches, shedding light on their unique theological emphases. This interdisciplinary exploration holds significance for understanding CCS and theology, especially in Asia, where a substantial Christian population and thriving megachurches exist. The study’s hypothesises is that despite both churches sharing a strong Pentecostal ethos, cultural differences will contribute to distinct expressions in song lyrics.

Both NCC and Hillsong underscore themes of love, God’s redemption, and the centrality of Christ’s atoning death and resurrection in their songs. Linguistically, cultural distinctions influence how God’s love is expressed by multilingual Singaporean songwriters compared with their native English-speaking Australian counterparts. Cultural differences between Asian and Australian churches are validated, with NCC prioritising personal righteous identity and spiritual growth, while Hillsong emphasises believers’ liberation and freedom in Christ. This research significantly contributes to understanding sung theology, offering insights into the nuanced theological expressions in megachurch congregational songs, particularly in diverse cultural contexts. Theological findings reveal that NCC focuses on the roles of Saviour, Sanctifier, Divine Healer, and Coming King, with limited attention to the Holy Spirit. In contrast, Hillsong emphasises the Saviour, Spirit Baptiser, and Coming King, with less emphasis on the Sanctifier and Divine Healer. NCC’s theological implication centres on the individual believer’s spiritual transformation towards conforming to Christ’s image, leaning towards Eastern orthodoxy. Hillsong expresses a more Western perspective, implicating the cosmic involvement of the Spirit in the broader redemptive narrative. This fundamental difference in pneumatological views underscores the distinct theological orientations of the two churches, with Trinitarian references present in Hillsong’s corpus but absent in NCC’s songs.
