from Venerable Louis of Granada:
Indeed the greatest proof of Christ’s love for his disciples at the Last Supper was the institution of the Blessed Sacrament . . . O great mystery which is deserving of being impressed on the very core of our hearts! If a prince were to love a slave and take her as his bride and make her queen of all that he possessed, we would acknowledge that such a love is indeed great. And if, after marriage, the slave’s love were to grow cold, and the prince were to go in search of something to re-awaken her love, this would be proof that his love is exceedingly great. So also, the King of glory took as his spouse our souls, which were slaves of the devil, and seeing how cold they were in love, he gave them this mysterious food which has the power to transform souls into himself which has the power to transform souls into himself and make them burn with the living flames of love. Nothing so manifests love as the desire to be loved, and he so desired our love that he invented this wonderful means of arousing it.
The Bridegroom had to absent himself from his spouse and since love will not tolerate a separation nor the absence of the beloved, he wished to depart from his spouse in such a way that he would not be separated from her completely; to leave her and yet somehow remain with her. He could no longer remain with her. He could no longer remain with her and she could not as yet accompany him, but although he was to go and she would remain, they would never henceforth be separated, thanks to this great Sacrament.
