No zoning ordinance or site plan review regulation shall prohibit, regulate, or restrict the use of land or structures primarily used for religious purposes; provided, however, that such land or structures may be subject to objective and definite regulations concerning the height of structures, yard sizes, lot area, setbacks, open space, and building coverage requirements as long as said requirements are applicable regardless of the religious or non-religious nature of the use of the property and do not substantially burden religious exercise.
