This study explores the impact of Gen-Z identity on the formation of faith, spirituality and religiosity, focusing on their characterization as the least religious generation and being labeled as “post-Christian”. Drawing on James Emery White’s framework of the Seventh Age, The Second Fall, The Rise of the Nones, and The Squish Center, the research investigates the declining active involvement of Gen-Z traditional religious settings. Contrary to a shift towards alternative religions, the study highlights a tendency among Gen-Z to redefine and neglect traditional religious definitions. The religious identity of Gen-Z is portrayed as less rigid compared to previous generations, shaped by the secularization, privatization, and pluralization context of their lives.

Understanding the distinctive characteristics of Gen-Z marked by factors such as being recession-marked, wifi enabled, multiracial, sexuality fluid, and post-Christian, is crucial for shaping their Christian identity and faith. The study employs a quantitative approach, utilizing surveys distributed to 621 respondents among Duta Wacana Christian University students over a four-year period (2020-2023). Findings indicate that religious identity of Gen-Z significantly influences the formation of their faith, spirituality and religiosity. Key factors related to their Christian identity include personal identity, friendships, the impact of COVID-19, Bible reading behavior, and social media usage. Analyzing the collected data, it is observed that Gen-Z in Indonesia tends to align with the “The Squish Center”, characterized by a flexible and adaptive approach to their beliefs and practices. Gen-Z is described as neither overly secular nor devoutly religious, embodying a nuanced position within the religious landscape.
