The Supreme Court case in Mount Tabor should already have provided the circuit court the proper boundary to prevent it from overstepping its jurisdiction.
Now, the Supreme Court has denied cert to another case, this time involving the Archdiocese of Saint Louis, and thus has upheld the proper sphere of authority of the Church.
As an aside, do you want to know my favorite cringeworthy line from the St. Stan's decision? One that really shows a subtle understanding of the essence of the Church -- "The Archbishop may own the souls of wayward St. Stanislaus parishioners, but the St. Stanislaus Parish Corporation owns its own property."
If, and I say if, there is any justice, the Missouri Court of Appeals should be applying a rolled-up newspaper to the trial court fairly quickly.
