Claim. The “seeker service” — a regularly scheduled, high-quality, deliberately church-jargon-stripped weekly service designed specifically for irreligious/unchurched visitors rather than the already-convinced — was crystallized by Bill Hybels at South Park Church (Chicago suburbs, mid-1970s) and became the foundational pattern of Willow Creek Community Church.
Elaboration. From iii-willow-creek-community-church: the moment of crystallization came after a service where Hybels read the crucifixion story, asked who wanted to receive Christ, and ~300 people stood. Walking out afterward in tears, Hybels recalls hearing God’s voice: “Where would those kids who received Christ tonight be if there hadn’t been a service designed just for them, a safe place where they could come week after week and hear the dangerous, life-transforming message of Christ?”
Hybels’s resulting pledge — “always make sure that our strategy includes a regularly scheduled, high-quality, Spirit-empowered outreach service where irreligious people can come and discover that they matter to You and that Christ died for them” — is what Hendricks identifies as “a good definition of the seeker service.”
Key design features: designed FOR the unchurched (not for the convinced bringing friends); high-quality production (music, drama, multimedia); Spirit-empowered conversion goal (not entertainment); regularly scheduled (not special-event); stripped of church-insider jargon.
UC analog: Hendricks describes the Unification movement as “in the process of building” guest-oriented evangelical programs (per growth-in-american-churches). The seeker-service template would make the Sunday primary service itself guest-friendly, not just one outreach program among many.
