"And just as He appeared before the holy Apostles in true flesh, so now He has us see Him in the Sacred Bread. Looking at Him with the eyes of their flesh, they saw only His Flesh, but regarding Him with the eyes of the spirit, they believed that He was God. In like manner, as we see bread and wine with our bodily eyes, let us see and believe firmly that it is His Most Holy Body and Blood, True and Living.
For in this way our Lord is ever present among those who believe in him, according to what He said: "Behold, I am with you all days even to the consummation of the world." (Mt. 28, 20)   - St. Francis of Assisi
