4 However We, who embrace the Eastern Church with no less solicitude and charity than our predecessors, truly rejoice, now that the frightful war is ended. We rejoice that many in the Eastern community have achieved liberty and wrested their holy things from the control of the laity. They are now striving to set the nation in order, consistent with the character of its people and the established customs of their ancestors. We propose, appropriately, a splendid example of sanctity, learning, and paternal love for them to diligently imitate and nurture. We speak of St. Ephrem the Syrian, whom Gregory of Nyssa compared to the River Euphrates because he "irrigated by his waters the Christian community to bring forth fruits of faith a hundred-fold." We speak of Ephrem, whom all the inspired orthodox Fathers and Doctors, including Basil, Chrysostom, Jerome, Francis of Sales, and Alphonsus Liguori, praise. We are pleased to join these heralds of truth, who though separated from each other in talent, in time and place, nevertheless perfect a harmony modulated by "one and the same spirit."
