Devotion to the Blessed Sacrament is the queen of all devotions. It is the central devotion of the Church. All others gather round it, and group themselves there as satellites; for others celebrate his mysteries; this is Himself. It is the universal devotion. No one can be without it, in order to be a Christian. How can a man be a Christian who does not worship the living Presence of Christ?
