1 We have already had the opportunity on several occasions during Our Pontificate of bearing public testimony to that confidence and devotion towards the Blessed Virgin which We imbibed in Our tenderest years, and have endeavoured to cherish and develop all our life long. For, having fallen upon times of calamity for Christendom and perils for the nations, We have realised how prudent it is to warmly recommend this means of safe-guarding happiness and peace which God has most mercifully granted to Mankind in His August Mother, and which bath ever been celebrated in the annals of the Church. The manifold zeal of Christian people has responded to Our desires and exhortations, most particularly in exciting a devotion to the Rosary; and a plentiful harvest of excellent fruits has not been wanting. Still we can never be satisfied with celebrating the Divine Mother, who is in truth worthy of all praise, and in urging love and affection towards her who is also the mother of mankind, who is full of mercy, full of grace . Yea, Our soul, wearied with the cares of the Apostolate, the nearer it feels the time of Our departure to be at hand, with the more earnest confidence looks up to her from whom, as from a blessed dawn, arose the Day of happiness and joy that was never to set. It is pleasant to us to remember, Venerable Brethren, that We have in other letters issued from time to time extolled the devotion of the Rosary; for it is in many ways most pleasing to her in whose honour it is employed, and most advantageous to those who properly use it. But it is equally pleasant to be able now to insist upon and confirm the same fact. Herein we have an excellent opportunity to paternally exhort men's minds and hearts to an increase of religion, and to stimulate within them the hope of eternal reward.
