There is a legal procedure in canon law in the Church. The property at Notre Dame essentially has been stolen by a group of heretics, anti-Catholics, and deviant clergy who oppose Church teachings and are abusing the property for their own twisted agenda. What should happen is canonical legal procedures should be pursued for the return of the property to lawful Catholic authorities in communion with the Church. And ALL of the anti-Catholics, heretics, liberals, and perverts should be fired and removed from the premises. That is what should happen.
Seen a lot of weird things in the Church, this was certainly one of the most embarrassing and disgraceful.
