Do you know the condition of the soul who receives unworthily? She is like a candle on which water has fallen, which can do nothing but crackle when brought near the flame, for no sooner has the fire touched it, than it is extinguished, and nothing remains but smoke; so this soul has cast the water of guilt within her mind upon the candle which she received in holy baptism, which has drenched the wick of the grace of baptism, and, not having heated it at the fire of true contrition and confession, goes to the table of the altar to receive this Light with her body, and not with her mind, wherefore the Light, since the soul is not disposed as she should be for so great a mystery, does not remain by grace in that soul, but leaves her, and, in the soul, remains only greater confusion, for her light is extinguished and her sin increased by her darkness. Of the Sacrament she feels nothing but the crackling of a remorseful conscience, not through the defect of the Light Itself, for that can receive no hurt, but on account of the water that was in the soul, which impeded her proper disposition so that she could not receive the Light. See, therefore, that in no way can this Light, united with its heat and its color, be divided, either by the scanty desire of the soul when she receives the Sacrament, or by any defect which may be in the soul, or by any defect of him who administers it, as I told you of the sun which is not defiled by shining on anything foul, so the sweet Light of this Sacrament cannot be defiled, divided, or diminished in any way, nor can it be detached from its orbit.
“If all the world should receive in communion the Light and Heat of this Sun, the Word, My only-begotten Son, would not be separated from Me—the True Sun, His Eternal Father—because in His mystical Body, the holy Church, He is administered to whoever will receive Him. He remains wholly with Me, and yet you have Him, whole God and whole man, as I told you, in the metaphor of the light, that, if all the world came to take light from it, each would have it entire, and yet it would remain whole.”
