Exponential documents a working lease-cost split: the coffee shop covers roughly six-sevenths of total costs, the church covers one-seventh, based on weekly hours of use.[8] They also note clearly: it is not sustainable for one person to serve as both café operator and church pastor. Constant operational demands require full attention from each. Basilea's model separates these roles from the beginning.
There's a legal dimension too. When a coffee shop operated by a religious organization becomes indistinguishable from an ordinary for-profit business, it can lose its tax-exempt status — a real outcome that's been documented.[11] The café must be excellent, and it must remain mission-aligned. Both matter.
