Well duh!
Hopefully, the significant consequences will include bankruptcy, lawsuits and making museums out of old churches. The ultimate irony would be for TEC to sell their unused churches to moslems just to show ecumenical support for fellow brothers of the book......
There is an interesting case of one such church in Chico, California. The parish split, with one group joining the APCK. The remaining group was too small to sustain the building, so they put it up for sale -- to anyone *other* than the APCK church.
It was finally sold to a fellow who turned it into an upscale Chinese restaurant, with a bar where the altar stood, a nightclub in the Sunday School, and so on. It was designated a historic building, though, so the exterior remain unchanged except for the removal of the cross from the steeple.
Seems the good people of Chico didn't feel comfortable eating in a former church, so the place went out of business several years later. This was a huge relief to the police, because they were forever being called to the nightclub, a draw for bad elements.
The church went up for sale again.
The university eyed it for a student center, and began investigating. As it turned out, the building did not meet the university's earthquake codes and so it went on the block again...
...to be bought by the APCK church, who set about removing and selling the restaurant/nightclub accretions, restoring the church to its original function. (One of the carpenters who worked on the restoration is also a deacon in that church.) During the process they discovered, and I have seen pictures of this, crosses that had been secreted behind walls and other places by the unknown workmen who converted the church to a restaurant.
Today St. Augustine's has been fully restored as an Anglican church, with a number of outreach missions, including student outreach and a mission to Iranians in the area.
