St. Alphonsus Liguori
“The servant of God and great Sicilian missionary-father, Louis La Nusa, was, even in his youth and as a layman, so enamoured of Jesus Christ, that he seemed unable to tear himself from the presence of his beloved Lord; and such were the joys which he there experienced, that his director, having commanded him, in virtue of obedience, not to remain there for more than an hour; when that time had elapsed, he showed in obeying (says the author of his life), that in tearing himself from the bosom of Jesus Christ, he had to do himself just such violence as a child which has to detach itself from its mother’s breast in the very moment in which it is satiating itself with the utmost avidity; and when he had to do this, we are told that he remained standing with his eyes cast on the altar, making repeated inclinations, as if he knew not how to quit his Lord, whose presence was so sweet and gracious to him.”
