18 Moreover, from the causes of hope and rejoicing which We have made known to you We cannot separate those tokens of love and obedience which you, venerable brethren, in these first days of Our pontificate, have shown Our lowliness, and with you so many of the clergy and the faithful, who by letters sent, by offerings given, by pilgrimages undertaken, and by other works of love, have made it clear that the devotion and charity which they manifested to Our most worthy predecessor still lasts, so strong and steadfast and unchanged as not to slacken toward the person of a successor so much inferior. For these splendid tokens of Catholic piety We humbly confess to the Lord that He is good and gracious, while to you, venerable brothers, and to all Our beloved children from whom We have received them, We publicly, from the bottom of Our heart, avow the grateful feelings of Our soul, cherishing the fullest confidence that, in the present critical state of things and in the difficulties of the times, this your devotion and love and the devotion and love of the faithful will never fail Us. Nor have We any doubt that these conspicuous examples of filial piety and Christian virtue will be of such avail as to make Our most merciful God, moved by these dutiful deeds, look with favor on His flock and grant the Church peace and victory. But as We are sure that this peace and victory will more quickly and more readily be given Us, if the faithful are unremitting in their prayers and supplications to obtain it, We earnestly exhort you, venerable brothers, to stir up for this end the zeal and ardor of the faithful, taking the Immaculate Queen of Heaven as their intercessor with God, and having recourse as their advocates to St. Joseph, the heavenly patron of the Church, and to Sts. Peter and Paul, the Princes of the Apostles. To the powerful patronage of all these We humbly commit Our lowliness, all ranks of the ecclesiastical hierarchy, and all the flock of Christ our Lord.
