10 In addition to the wrongs and injuries to which we have so far referred, the Law of Separation also violates and tramples under foot the rights of property of the Church. In defiance of all justice, it despoils the Church of a great portion of a patrimony which belongs to her by titles as numerous as they are sacred; it suppresses and annuls all the pious foundations consecrated, with perfect legality, to divine worship and to suffrages for the dead. The resources furnished by Catholic liberality for the maintenance of Catholic schools, and the working of various charitable associations connected with religion, have been transferred to lay associations in which it would be idle to seek for a vestige of religion. In this it violates not only the rights of the Church, but the formal and explicit purpose of the donors and testators. It is also a subject of keen grief to Us that the law, in contempt of all right, proclaims as property of the State, Departments or Communes the ecclesiastical edifices dating from before the Concordat. True, the Law concedes the gratuitous use, for an indefinite period, of these to the associations of worship, but it surrounds the concession with so many and so serious reserves that in reality it leaves to the public powers the full disposition of them. Moreover, We entertain the gravest fears for the sanctity of those temples, the august refuges of the Divine Majesty and endeared by a thousand memories to the piety of the French people. For they are certainly in danger of profanation if they fall into the hands of laymen.
