9 Nor may we permit to pass unnoticed the especial Providence of God displayed in this devotion; for through the lapse of time religious fervour has sometimes seemed to diminish in certain nations, and even this pious method of prayer has fallen into disuse; but piety and devotion have again flourished and become vigorous in a most marvellous manner, when, either through the grave situation of the commonwealth or through some pressing public necessity, general recourse has been had-more to this than to even other means of obtaining help - to the Rosary, whereby it has been restored to its place of honour on the altars. But there is no need to seek for examples of this power in a past age, since we have in the present a signal instance of it. In these times - so troublous (as we have said before) for the Church, and so heartrending for ourselves - set as We are by the Divine will at the helm, it is still given Us to note with admiration the great zeal and fervour with which Mary's Rosary is honoured and recited in every place and nation of the Catholic world. And this circumstance, which assuredly is to be attributed to the Divine action and direction upon men, rather than to the wisdom and efforts of individuals, strengthens and consoles Our heart, filling Us with great hope for the ultimate and most glorious triumph of the Church under the auspices of Mary.
