There is a certain peculiarity which is attached to this word. For when it calls the soul to itself, it excites a congealing power in everything which is earthly, or corporeal, or under the influence of the external senses. On which account it is said to be "like the hoar-frost on the Earth." For when the man who beholds God, meditates a flight from the passions, "the waves are frozen," that is to say, the impetuous rush, and the increase, and the haughty pride of the waves are arrested, in order that he who might behold the living God might then pass over the Passion. Therefore the souls inquire of one another, those, that is, that have clearly felt the influence of the word, but which are not able to say what it is. For very often, when sensible of a sweet taste, we are nevertheless ignorant of the flavour which has caused it, and when we smell sweet scents, we still do not know what they are. And in the same manner also the soul very often, when it is delighted, is yet unable to explain what it is that has delighted it; but it is taught by the hierophant and prophet Moses, who tells it, "This is the bread, the food which God has given for the Soul," explaining that God has brought it, his own word and his own reason; for this bread which he has given us to eat is this word of his.
25 When they found him on the other side of the lake, they said to him, “Rabbi, when did you get here?” 26 Jesus replied, “I tell you the solemn truth, you are looking for me not because you saw miraculous signs, but because you ate all the loaves of bread you wanted. 27 Do not work for the food that disappears, but for the food that remains to eternal life—the food which the Son of Man will give to you. For God the Father has put his seal of approval on him.”
28 So then they said to him, “What must we do to accomplish the deeds God requires?” 29 Jesus replied, “This is the deed God requires—to believe in the one whom he sent.” 30 So they said to him, “Then what miraculous sign will you perform, so that we may see it and believe you? What will you do? 31 Our ancestors ate the manna in the wilderness, just as it is written, ‘He gave them bread from heaven to eat.’”
32 Then Jesus told them, “I tell you the solemn truth, it is not Moses who has given you the bread from heaven, but my Father is giving you the true bread from heaven. 33 For the bread of God is the one who comes down from heaven and gives life to the world.” 34 So they said to him, “Sir, give us this bread all the time!”
35 Jesus said to them, “I am the bread of life. The one who comes to me will never go hungry, and the one who believes in me will never be thirsty. 36 But I told you that you have seen me and still do not believe. 37 Everyone whom the Father gives me will come to me, and the one who comes to me I will never send away. 38 For I have come down from heaven not to do my own will but the will of the one who sent me. 39 Now this is the will of the one who sent me—that I should not lose one person of every one he has given me, but raise them all up at the last day. 40 For this is the will of my Father—for everyone who looks on the Son and believes in him to have eternal life, and I will raise him up at the last day.”
