“O inestimable charity! Even as You, true God and true man, gave Yourself entirely to us, so also You left Yourself entirely for us, to be our food, so that during our earthly pilgrimage we would not faint with weariness, but would be strengthened by You, our Celestial Bread. O man, what has your God left you? He has left you Himself, wholly God and wholly man, concealed under the whiteness of bread. O fire of love! Was it not enough for You to have created us to Your image and likeness, and to have recreated us in grace through the Blood of Your Son, without giving Yourself wholly to us as our food, O God, Divine Essence? What impelled You to do this? Your charity alone.” — St. Catherine of Siena
