The voice of Jerome summons those Christian nations which have unhappily fallen away from Mother Church to turn once more to her in whom lies all hope of eternal salvation. Would, too, that the Eastern Churches, so long in opposition to the See of Peter, would listen to Jerome’s voice. When he lived in the East and sat at the feet of Gregory and Didymus, he said only what the Christians of the East thought in his time when he declared that “If anyone is outside the Ark of Noë he will perish in the overwhelming flood.” Today this flood seems on the verge of sweeping away all human institutions — unless God steps in to prevent it. And surely this calamity must come if men persist in sweeping on one side God the Creator and Conserver of all things! Surely whatever cuts itself off from Christ must perish! Yet He Who at His disciples’ prayer calmed the raging sea can restore peace to the tottering fabric of society. May Jerome, who so loved God’s Church and so strenuously defended it against its enemies, win for us the removal of every element of discord, in accordance with Christ’s prayer, so that there may be “one fold and one shepherd.” Encyclical Letter Spiritus Paraclitus of Pope Benedict XV.
