The Intergenerational Integration Question

Over the past half-century, Adventist churches have progressively separated young people from the broader congregation — creating youth Sabbath Schools, youth churches, youth events, and youth programmes that operate as parallel institutions alongside (rather than within) the adult church. This age-segregation model, adopted largely from North American evangelical youth ministry culture, was intended to make church more relevant and engaging for young people. But a growing body of evidence suggests it may have had the opposite effect: by separating youth from the intergenerational community, age-segregated programming may have inadvertently weakened the relational bonds, identity formation, and sense of belonging that keep young people connected to the church long-term. This Living Research Project examines the evidence on intergenerational integration versus age-segregated programming, drawing on the Fuller Youth Institute's Sticky Faith and Growing Young research, Effective Ministry's Australian literature synthesis, peer-reviewed studies from Christian Education Journal and Archive for the Psychology of Religion, and cross-denominational data. The evidence points toward a consistent conclusion: churches that intentionally integrate young people into the life of the whole congregation demonstrate better retention outcomes than those that primarily separate them into age-specific tracks. The global Adventist retention context makes this question urgent. In 2023, approximately 836,905 people left the church, with a net loss rate of 42.5% over the past 60 years (GC ASTR 2023 data). Meanwhile, new Barna data (September 2025) shows Gen Z and Millennials now leading a resurgence in churchgoing, with younger generations moving from "just over one weekend per month in 2020 to nearly two in 2025" ([Barna Group, 2025](https://www.barna.com/research/young-adults-lead-resu
