St. Alphonsus Liguori
“My Lord, would it not have been enough hadst Thou remained in this Sacrament only during the day, when Thou couldst have had adorers of Thy presence to keep Thee company; but why remain also the whole night, when the churches are all closed, and when men retire to their homes, leaving Thee quite alone? Ah, yes! I already understand Thee: love has made Thee our prisoner; the excessive love which Thou nearest us has so bound Thee down on earth, that neither night nor day canst Thou leave us. Ah, most amiable Saviour, this refinement of love alone should oblige all men ever to stay with Thee in the sacred ciboriums, and to remain with Thee until forcibly compelled to leave Thee; and when they do so, they should all leave at the foot of the altar their hearts and affections inflamed with love towards an Incarnate God, who remains alone and enclosed in a tabernacle, all eyes to see and provide for them in their necessities, and all heart to love them, and who awaits the coming day to be again visited by His beloved souls.”
