If so, it's the same thing in the Diocese of Joliet. Our parish had to borrow from the Diocese to complete its Parish Life Center, and is paying it back with interest.
A trustee may hold title but that does not make it the owner. It holds title in trust for the beneficiaries. If anyone here has his home in a land trust, I don't think he or she would be happy if the trustee went bankrupt and its creditors take your house to pay the trustee's debts. But because the trustee is not the real owner of the asset, a creditor cannot seize it.
It may also be the case that the diocese, not as trustee but as the leader of area parishes, has oversight over how a parish handles its assets, just as a land trustee can also be a mortgage holder on the same property. In neither situation does the trustee actually "own" or even "control" the asset, and in neither situation can a creditor of the trustee seize the asset. I have not read the Portland decision, but perhaps the court found that the oversight component was sufficient to override the beneficial interest component. If so, that's an appealable issue.
As for St. Louis, that is completely different case with different issues and should not be compared with Portland. And if I remember correctly, the Archdiocese of St. Louis is not demanding that St. Stanislaus turn over its assets to the Archdiocese; it is merely requesting the same oversight that any diocese is entitled to over any parish.
