15 Therefore, God, who has "exalted the humble," bestows great glory on blessed Ephrem and proposes him to this age as a doctor of heavenly wisdom and an example of the choicest virtues. And the appropriateness of his example is truly singular today. The frightful war is over and there is something of a new order for many nations, especially in the East. We, along with you and all good men, must endeavor to restore in Christ whatever remains of human and civil culture and to recall the erring society of men to God and to His Holy Church. Though our ancestors' institutions failed, public affairs are in tumult, and everything human is confused, the Catholic Church alone never vacilates, but instead looks confidently to the future. She alone is born for immortality, trusting in the words addressed to Blessed Peter: "Upon this rock I will build my Church and the gates of hell will not prevail against her."
