12 And yet that is precisely what was done in the matter of the associations cultuelles . They were organized under the law in such a way that its dispositions on this subject ran directly counter to those rights which, derived from her constitution, are essential to the Church, notably as affecting the ecclesiastical hierarchy, the inviolable base given to His work by the Divine Master himself. Moreover, the law conferred on these associations powers which are the exclusive prerogative of ecclesiastical authority both in the matter of the exercise of worship and of the proprietorship and administration of property. And lastly, not only are these associations withdrawn from ecclesiastical jurisdiction but they are made judicially answerable to the civil authority. These are the reasons which have driven Us in Our previous Encyclicals to condemn these associations cultuelles in spite of the heavy sacrifices which such condemnation involved.
