The support it needs above all is common sense.
The veneration of the Virgin in a hermitage in empty Spain with no inhabitants in its locality or in the surrounding ones is absolute nonsense. That hermitage would be empty every single day. Whereas thousands of people come to the church where she is now venerated, located just a few meters from the hermitage. People who also venerate that Virgin.
So that foolish bishop who wants to present himself as the great defender of the Virgin of Torreciudad, if what he intends is accepted, will achieve that no one comes to the Virgin in an empty hermitage.
If he barely has priests in his diocese to dedicate one to a devotion that no one will attend in an empty hermitage that only the dust will visit.
