A court may resolve the dispute when the case can be decided solely on the application of neutral principles of law, without reference to any religious principle. The court must apply objective, well-established principles of secular law, and may rely on internal church governing documents only to the extent that they do not require the interpretation of ecclesiastical doctrine.
