Let the world shake…

Let the whole world of mankind tremble the whole world shake and the heavens exult when Christ, the Son of the living God, is on the altar in the hands of a priest. O admirable heights and sublime lowliness! O sublime humility! O humble sublimity! That the Lord of the universe, God and the Son of God, so humbles Himself that for our salvation He hides Himself under the little form of bread! Look, brothers, at the humility of God and pour out your hearts before Him! Humble yourselves, as well, that you may be exalted by Him. Therefore, hold back nothing of yourselves for yourselves so that He Who gives Himself totally to you may receive you totally.
–Saint Francis of Assisi (1181–1226)
