William J. Brennan, Jr., Presbyterian Church in the United States v…
“ Even if the general church had attempted to apply the state standard, the civil courts could not review and enforce the church decision without violating the Constitution. The First Amendment prohibits a State from employing religious organizations as an arm of the civil judiciary to perform the function of interpreting and applying state standards. See School District of Township of Abington, Pa. v. Schempp, supra. Thus, a civil court may no more review a church decision applying a state departure-from-doctrine standard than it may apply that standard itself. ”
