Sempiternus Rex Christus §39

³⁹ When the recent war was waging and producing its fruits of famine, want and disease, we made no distinction between them and those who are accustomed to call us Father, but sought everywhere to relieve the increasing misery; we strove to help widows, children, old people and the sick. We would have been happier truly had our means been equal to our desires! Let those then who, through the calamities of time, have been cut off, not be slow to pay due respect to this divinely erected and unbroken rock, this Apostolic See for whom to rule is to serve. Let them bear in mind and imitate Flavian, that second John Chrysostom, in his sufferings for justice; and the fathers of Chalcedon, those most worthy members of the Mystical Body of Christ; and Marcian, that strong, gentle and wise ruler; and Pulcheria, that resplendent lily of inviolate royal beauty. From such a return to the unity of the Church we foresee that there would flow a rich fountain of blessings unto the common good of the whole Christian world.
