Robert H. Schuller's Crystal Cathedral in Garden Grove, California, appeared to be the model of growth and stability among megachurches—until it imploded. Drawing on archival material and interviews, this article demonstrates how the seeming success of Schuller's church growth philosophy was built on a precarious structure that demanded the continual management of flows of capital. In Schuller's vision, a church's capacity must always exceed a leader's projected plan for growth. Large capital projects stimulate revenue, yet borrowed funds are required to accommodate growth in membership that will produce income to pay off loans later. As new members join, however, structures expand, placing increased strain on mobilizing the loyalty of a wider constituency to uphold the charisma-bearing enterprise. Ensuring the credibility of pastoral charisma requires ever expanding infrastructure, which, in turn, demands increased funding for programs, staff, and buildings—a vicious spiral, exacting enormous strains for sustaining the entire ministry.
