HAKIKAT, FUNGSI, DAN MISI GEREJA: KAJIAN TEOLOGI SISTEMATIKA DAN RELEVANSINYA BAGI GEREJA MASA KINI

Abstrak

Artikel ini mengkaji hakikat, fungsi, dan misi gereja dalam perspektif teologi sistematika serta relevansinya bagi kehidupan gereja masa kini. Studi eklesiologi yang bersifat komprehensif dan berbasis Alkitab masih sangat diperlukan di tengah meningkatnya tantangan sekularisme, pluralisme, dan transformasi digital yang dihadapi gereja di Indonesia. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi pustaka (library research) dan analisis teologi sistematis terhadap sumber-sumber primer berupa teks Alkitab dan karya-karya teolog eklesiologi dari Erickson, Berkhof, Grudem, Bosch, dan Stott. Hasil kajian menunjukkan bahwa (1) gereja memiliki hakikat ganda: ilahi sebagai karya Allah melalui Kristus dan Roh Kudus, sekaligus manusiawi sebagai komunitas orang percaya; (2) fungsi gereja mencakup empat dimensi yang saling terintegrasi, yaitu koinonia (persekutuan), marturia (kesaksian), diakonia (pelayanan), dan leiturgia (ibadah); serta (3) misi gereja bersumber dari missio Dei yang melampaui dimensi penginjilan semata, mencakup transformasi sosial dan pemeliharaan ciptaan. Kontribusi utama penelitian ini terletak pada sistematisasi keempat fungsi gereja dalam satu kerangka terpadu yang aplikatif, serta tawaran model eklesiologi kontekstual yang responsif terhadap tantangan gereja di Indonesia kontemporer.

This article examines the nature, functions, and mission of the church from the perspective of systematic theology and their relevance to contemporary church life. A comprehensive and biblically grounded study of ecclesiology remains highly necessary amid the increasing challenges of secularism, pluralism, and digital transformation faced by churches in Indonesia. This study employs a qualitative approach using library research and systematic theological analysis of primary sources, including biblical texts and ecclesiological works by Erickson, Berkhof, Grudem, Bosch, and Stott. The findings reveal that: (1) the church possesses a dual nature—divine as the work of God through Christ and the Holy Spirit, and human as a community of believers; (2) the functions of the church encompass four integrated dimensions, namely koinonia (fellowship), marturia (witness), diakonia (service), and leiturgia (worship); and (3) the mission of the church originates from missio Dei, extending beyond mere evangelism to include social transformation and the stewardship of creation. The primary contribution of this study lies in the systematization of the four functions of the church within an integrated and applicable framework, as well as the proposal of a contextual ecclesiological model that is responsive to the challenges faced by contemporary churches in Indonesia.
