13 In this hard trial of France, if all those who wish to defend with all their power the supreme interests of their country work as they ought to do in union among themselves with their Bishops and with Ourselves for the cause of religion, far from despairing of the welfare of the Church of France, it is to be hoped, on the contrary, that she will be restored to her former prosperity and dignity. We in no way doubt that the Catholics will fully comply with Our directions, and conform with Our desires: and We shall ardently seek to obtain for them by the intercession of Mary, the Immaculate Virgin, the aid of the Divine goodness.
