This chapter of the Evangelist, which I should like to read with you entire, concludes with an exhortation to watch and pray in order to shun all these misfortunes, and in truth, it is proper indeed that when the danger is continual the prayer should be continual also.
For this purpose I send the prayers which were asked of me; it is now three an the afternoon. Since your departure, a miracle has been performed upon a nun of Pontoise, who, without leaving her convent, has been cured of an extraordinary headache by an act of devotion to the holy Thorn. I will tell you more about it another time. But I must quote to you, in respect to this, an excellent saying of St. Augustine, very consoling to certain persons, that those alone really see miracles whom the miracles benefit; for they are not seen at all if they do not benefit.
I am under obligations that I cannot sufficiently express for the present which you have made me; I did not know what it could be, for I unfolded it before reading your letter, and I afterwards repented for not having rendered to it at first the respect that was due to it. It is a truth that the Holy Spirit reposes invisibly in the relics of those who have died in the grace of God, until they shall appear visibly in the resurrection, and this it is that renders the relics of the saints so worthy of veneration. For God never abandons his own, even in the sepulchre in which their bodies, though dead to the eyes of men, are more than ever living in the sight of God, since sin is no more in them; whilst it constantly resides in them during life, at least in its root, for the fruits of sin are not always in them; and this fatal root, which is inseparable from them in life, causes it to be forbidden us during life to honor them, since they are rather worthy of detestation. It is for this that death becomes necessary to mortify entirely this fatal root, and this it is that renders it desirable. But it is of no use to tell you what you know so well; it would be better to tell it to the other persons of whom you speak, but they would not listen to it.
