Here are some of the cases discussed in the posts linked. It is a good discussion for someone trying to get a handle on some of the legal issues. I have improved some of the links:
SERBIAN ORTHODOX DIOCESE v. MILIVOJEVICH, 426 U.S. 696 (1976)

Jones v. Wolf , 443 U.S. 595 (1979)
http://laws.findlaw.com/us/443/595.html
I haven't found a good public link to Norfolk Presbytery v. Bollinger, 214 Va. 500, 1974, but would note that it should be relied upon with caution in that it predates Jones v. Wolf.
Scotts Church v. Conference of African Union First Colored Methodist Protestant Church
