2 Accordingly, Venerable Brethren, it has seemed good to Us to address you on certain points connected with this same mystery, for the defence and honour of which the solicitude of the Church has been so constantly engaged, for which Martyrs have given their lives, which has afforded to men of the highest genius a theme to be illustrated by their learning, their eloquence, their skill in all the arts; and this We will do in order to render more clearly evident and more widely known those special characteristics by virtue of which it is so singularly adapted to the needs of these our times. It was towards the close of His mortal life that Christ our Lord left this memorial of His measureless love for men, this powerful means of support "for the life of the world" (St. John vi., 52). And precisely for this reason, We, being so soon to depart from this life, can wish for nothing better than that it may be granted to us to stir up and foster in the hearts of all men the dispositions of mindful gratitude and due devotion towards this wondrous Sacrament, wherein most especially lie, as We hold, the hope and the efficient cause of salvation and of that peace which all men so anxiously seek.
