The Supreme Court agreed on Thursday to decide whether a zoning board can stop a church from building a religious structure on land the church already owns.

The case comes out of Park Hills, Kentucky. The Missionaries of St. John the Baptist, an order of Catholic priests, wanted a prayer grotto next to their church.

The plan was modest by any measure. A structure sixteen feet by thirty-nine feet, roughly six hundred square feet in all, holding a shrine to the Virgin Mary, a plaza, a walking path and a retaining wall.

The city approved it. The Park Hills Board of Adjustment granted the conditional-use permit in April 2021.

Then two neighbors sued. Joel and Elizabeth Frederic challenged the permit in Kentucky state court, and the litigation has now outlived the approval by more than five years.

The trial court sided with the priests. The Kentucky Court of Appeals reversed, holding that the board had exceeded its authority, and the Kentucky Supreme Court affirmed that reversal in December 2025. That left the grotto dead and the order out of options in its own state.

What the priests have left is a federal statute. The Religious Land Use and Institutionalized Persons Act, passed in 2000, bars government from placing a substantial burden on religious exercise through land-use rules unless it can clear a high bar.

The question the justices agreed to answer is narrow on its face and enormous underneath. Whether telling a religious institution it may not build a religious structure on its own property is a substantial burden under that law.

The order is represented by First Liberty Institute. Senior counsel Ryan Gardner told Fox News what he believes is at stake.

“This is a massive case for religious liberty because it has the potential to impact every single zoning law in this country,” Gardner said.

He is not overstating the reach. Zoning is how most disputes over churches, synagogues and mosques actually get settled in America, and they get settled in county buildings rather than courtrooms.

A parish wants a larger sanctuary. A congregation wants to meet in a storefront. A ministry wants to feed people in a parking lot. Each one runs into a code, a setback, a permit and a board.

Almost none of those disputes ever reach a federal judge. They end when the applicant gives up, which is why a ruling on what counts as a substantial burden would reach far beyond one grotto in a town of three thousand people.

The Washington Times reported the grant as part of a religious liberty docket the Court is assembling for this term.

Argument has not been scheduled. A decision is expected by the end of the term.
