15 From the point of view of ecclesiastical property, this law is a law of spoliation and confiscation, and it has completed the stripping of the Church. Although her Divine Founder was born poor in a manger, and died poor on the Cross, although she herself has known poverty from her cradle, the property that came to her was nonetheless hers, and no one had the right to deprive her of it. Her ownership, indisputable from every point of view, had been, moreover, officially sanctioned by the state, which could not consequently violate it. From the point of view of the exercise of worship, this law has organized anarchy; it is the consecration of uncertainty and caprice. Uncertainty whether places of worship, always liable to be diverted from their purpose, are meanwhile to be placed, or not placed, at the disposition of the clergy and faithful; uncertainty whether they shall be reserved from them or not, and for how long; whilst an arbitrary administrative regulates the conditions of their use, which is rendered eminently precarious. Public worship will be in as many diverse situations as the other. On the other hand, there is an obligation to meet all sorts of heavy charges, whilst at the same time there are draconian restrictions upon the resources by which they are to be met. Thus, though but of yesterday, this law has already evoked manifold and severe criticisms from men belonging indiscriminately to all political parties and all shades of religious belief. These criticisms alone are sufficient judgment of the law.
