Supreme Court to hear Kentucky prayer grotto case with potential nationwide zoning implications

The Supreme Court has agreed to take up a case that began with a modest proposal: a Catholic church in Park Hills, Kentucky, wanted to build a prayer grotto on its own property. The structure—a 16-by-39-foot shrine to the Virgin Mary, complete with a plaza, walking path, and retaining wall—would occupy roughly 600 square feet, about the size of a swimming pool. But this small devotional space has landed before the nation's highest court with implications that could reshape how zoning laws interact with religious freedom across the country.

The Missionaries of St. John the Baptist submitted their application for a conditional-use permit and variance in March 2021. The church building itself had occupied the property for nearly a century, predating the town's zoning ordinance by decades. The local Board of Adjustment approved the permit in April 2021. But the fight was not over. Two neighboring property owners, Joel and Elizabeth Frederic, objected and challenged the decision in Kentucky state court.

What followed was a legal reversal. A trial court sided with the church, but the Kentucky Court of Appeals overturned that ruling, concluding the board had exceeded its authority and finding no violation of federal religious land-use law. The Kentucky Supreme Court affirmed that decision in December 2025, leading the church to petition the U.S. Supreme Court for review. The justices agreed to hear the case, though they narrowed the question they would consider: Does prohibiting a religious institution from building a religious structure on its own property constitute a "substantial burden" on religious exercise under federal law?

At the heart of the dispute lies the Religious Land Use and Institutionalized Persons Act, or RLUIPA, enacted by Congress in 2000. The law was designed to protect religious organizations from certain government restrictions on how they use their property. Ryan Gardner, senior counsel at First Liberty Institute, which represents the church, told Fox News that the implications extend far beyond one Kentucky grotto. "This is a massive case for religious liberty because it has the potential to impact every single zoning law in this country," he said.

The problem Gardner identifies is fragmentation. Since RLUIPA's passage, federal and state courts have developed different approaches to determining what counts as a "substantial burden" under the law. Religious organizations face different levels of protection depending on where their disputes arise. The Supreme Court now has an opportunity to establish a clearer, nationwide standard. Gardner argues that zoning regulations, while serving legitimate local purposes, remain subject to federal protections for religious exercise—a principle that reaches well beyond this single case.

The Frederics disputed this characterization in their opposition brief, arguing that appellate courts generally apply similar factors and that different outcomes often reflect different facts. They also contended that the church failed to demonstrate that no alternative locations existed for the grotto. An attorney for the Frederics did not respond to requests for comment.

The case sits at the intersection of two constitutionally significant areas: religious liberty and local government authority over property use. Gardner warned that an overly narrow interpretation of RLUIPA could have "dire consequences" for religious land use nationwide. A ruling in the church's favor could affect disputes involving churches, synagogues, ministries, and other religious organizations seeking to use their properties for worship or religious activities. The Supreme Court's decision will likely establish precedent that shapes how communities balance zoning regulations against the religious exercise rights of institutions within their borders.
