Athanasius of Alexandria : What advancement, then, was it to the Immortal to have assumed the mortal? Or what promotion is it to the Everlasting to have put on the temporal? What reward can be great to the everlasting God and King in the bosom of the Father? Do you not see that this too was done and written because of us and for us, that the Lord, having become a human being, might make immortal us who are mortal and temporal and bring us into the everlasting kingdom of heaven? Do you Arians not blush, speaking lies against the divine oracles? For when our Lord Jesus Christ was among us, we indeed were promoted, as rescued from sin; but he is the same, nor did he change when he became man, but, as has been written, "the Word of God abides forever." Surely as, before he became human, he, the Word, dispensed to the saints the Spirit as his own, so also when made human, he sanctifies all by the Spirit and says to his disciples, "Receive the Holy Spirit." — Discourses Against the Arians 1.12.48 Augustine of Hippo : Wonder not that you will be a sharer of [Christ's] eternity. For he first became a sharer of your flesh, which is like grass. Will he who assumed from you what was lowly deny to you what is exalted with respect to you?… How great, then, is the hope of the grass since the Word has been made flesh? He who abides forever has not disdained to assume grass, that the grass might not despair of itself. — EXPLANATIONS OF THE Psalms 103:19-21 Augustine of Hippo : So those flourishing, wicked people are like grass, sprouting in winter, drying up in summer. Take care that you, though, fix your roots in the Word of God, which abides forever, and that you are a tree living in a hidden way. "For you are dead, and your life is hidden with Christ in God." That is where your root is; that is where you are alive. That, you see, is where you have placed your hope.… So do not let the winter time get you down. In the winter many prolific fruit trees lack the ornament of leaves and without the grace of fruit are like withered trees, and yet they are not in fact withered. When the grass is flourishing, they haven't even got leaves … the summer is the judge … the sun of justice is the judge. — SERMON 25A.1 Augustine of Hippo : Both what is being thought of by intelligence and what is sounding out loud in speech is changeable and dissimilar. The first will not remain when you have forgotten it, nor will the second when you stop speaking. But "the Word of the Lord remains forever" and abides unchanged and unchangeable. — SERMON 187:3 Basil of Caesarea : "The voice of the Lord is on the waters." In many places you might find the word voice occurring. Therefore, for the sake of understanding what the voice of the Lord is, we should gather, as far as we are able, from the divine Scripture what has been said about the voice; for instance, in the divine warning to Abraham: "And immediately the voice came to him: He shall not be your heir." And in Moses: "And all the people saw the voice and the flames." Again in Isaiah: "The voice of one saying, Cry." With us, then, voice is either air that has been struck or some form that is in the air against which he who is crying out wishes to strike. Now, what is the voice of the Lord? Would it be considered the impact on the air? Or air, which has been struck reaching the hearing of him to whom the voice comes? Or neither of these but that this is a voice of another kind, namely, an image formed by the mind of people whom God wishes to hear his own voice, so that they have this representation corresponding to that which frequently occurs in their dreams? Indeed, just as, although the air is not struck, we keep some recollection of certain words and sounds occurring in our dreams, not receiving the voice through our hearing but through the impression on our heart itself, so also we must believe that some such voice from God appeared in the prophets. — HOMILIES ON THE Psalms 13:3 (Psalms 28) Basil of Caesarea : I want the marvel of creation to gain such complete acceptance from you that, wherever you may be found and whatever kind of plants you may chance on, you may receive a clear reminder of the Creator. First, then, whenever you see a grassy plant or a flower, think of human nature, remembering the comparison of the wise Isaiah, that "all flesh is as grass, and all the glory of humanity as the flower of the grass." For the short span of life and the briefly enduring pleasure and joy of human happiness have found a most apt comparison in the words of the prophet. Today he is vigorous in body, grown fleshy from delicacies, with a flowerlike complexion, in the prime of life, fresh and eager, and irresistible in attack. Tomorrow that same one is piteous or wasted with age or weakened by disease. — HOMILIES ON THE HEXAMERON 5:2 Bede : Let all who long to be refreshed by the sweetness of the living bread, all who love to be renewed by the banquet of heavenly grace, sit down on the grass. Let them trample on the bloom of the grass. Let them chastise the body and subject it to slavery. — Homilies on the Gospels 2:2 Cyril of Alexandria : The Word of the Father dwells in our hearts through faith. When we receive the riches of his divine Spirit, then we have him in ourselves as that which is most worth having, since he is the giver of eternal life. For when the Word dwells in us, he remains there forever, sustaining and enlivening us. Now if anyone wishes to know from the Word of God his commandment, then we say that this is immeasurably useful. For God guards both the commandment and those who observe it for the life which is yet to come. As was said by the Lord himself, "Truly I tell you, that if anyone keeps my word, he shall not see death." — COMMENTARY ON Isaiah 3:4.40:6-8 Eusebius of Caesarea : This is the nature of all flesh and of the human who bears the image of the earthly; I mean the body-lover who lives according to the flesh. In like manner the grass of the earth and the beautiful flowers rise up and bloom for a short time, but soon they wither through their unstable nature.… The voice in the desert prophesying about God the Word is John teaching about Christ, as only from then on will it stand forever, and it guards those who stand with it and run with it as those who are becoming models of its salvation. — COMMENTARY ON Isaiah 2:16 Jerome : (Verse 6 and following) The voice of one saying, Cry out. And I said, What shall I cry out? All flesh is grass, and all its glory is like the flower of the field. The grass withers, the flower falls; because the breath of the LORD blows upon it. Truly the people are grass. The grass withers, the flower falls; but the word of our God will stand forever. (LXX: The voice of one saying, Cry out. And I said, What shall I cry out? All flesh is grass, and all the glory of man is like the flower of grass.) The grass withers, and the flower falls; because the breath of the Lord blows upon it. Surely the people are grass. The grass withers, the flower falls. But the word of our God remains forever. This portion marked with asterisks is added from the Hebrew and Theodotion's edition. From this it is clear that it was either omitted by the LXX or gradually lost through the error of scribes, since both the preceding and following verses end with 'flower'. Above we have read, the Prophet saying: And I heard the voice of the Lord saying: Whom shall I send, and who will go to this people? And I said: Here I am, send me; and he said: Go and tell this people: Hearing you will hear, and will not understand: and seeing you will see, and will not perceive, and so on. After enduring a harsh preaching, now the voice of the Lord saying, he asks what he should shout, fearing similar things; and starting from the general, All flesh is grass, and all its glory like the flower of the grass, he comes to the particular, so that he may still say about the people: Truly the people are grass. And in truth, if anyone were to consider the frailty of the flesh, and how we grow and decline in a matter of hours, and do not remain in the same state: and that which we speak, dictate, and write, passes quickly from our lives: he will not hesitate to call the flesh hay, and its glory as the flower of hay, or the meadows of the fields. For the one who was recently an infant suddenly becomes a child; the child suddenly becomes a young person; and throughout the uncertain passage of time, he is transformed into old age; and he realizes himself to be old before he marvels at no longer being young. A beautiful woman who drew after her flocks of young men, is contracted in her countenance: and she who was once for love, afterwards is for disdain. Which an excellent orator among the Greeks writes: The beauty of the body either fails with time, or is consumed by sickness. Therefore the flesh is withered, and the beauty is fallen off; because the spirit of the madness of God and of his sentence has blown upon her (that I may return from a general discourse to the order of the Scripture), of him who bears the image of the earthly, and serves vices and luxury; and he is like hay and a passing flower. But whoever has and keeps the image of the heavenly, that person is the flesh which sees the salvation of the Lord, which is daily renewed in knowledge according to the image of the Creator, and receiving an incorruptible and immortal body, changes glory, not nature. But the word of our Lord, and those who are associated with the word, endure forever. — Commentary on Isaiah Jerome : We are still alive, but part of us has already perished in old age. Even though our soul is the same, nevertheless, we who suffer the loss of the pristine vigor of youth are, in a real sense, other than we were. — HOMILIES ON THE PSALMS, ALTERNATE SERIES 67 (Psalms 89) Jerome : And in truth, if anyone were to consider the frailty of the flesh, and how we grow and decline in a matter of hours, and do not remain in the same state: and that which we speak, dictate, and write, passes quickly from our lives: he will not hesitate to call the flesh hay, and its glory as the flower of hay, or the meadows of the fields. For the one who was recently an infant suddenly becomes a child; the child suddenly becomes a young person; and throughout the uncertain passage of time, he is transformed into old age; and he realizes himself to be old before he marvels at no longer being young. A beautiful woman who drew after her flocks of young men, is contracted in her countenance: and she who was once for love, afterwards is for disdain. Which an excellent orator among the Greeks writes: The beauty of the body either fails with time, or is consumed by sickness. Therefore the flesh is withered, and the beauty is fallen off; because the spirit of the madness of God and of his sentence has blown upon her (that I may return from a general discourse to the order of the Scripture), of him who bears the image of the earthly, and serves vices and luxury; and he is like hay and a passing flower. But whoever has and keeps the image of the heavenly, that person is the flesh which sees the salvation of the Lord, which is daily renewed in knowledge according to the image of the Creator, and receiving an incorruptible and immortal body, changes glory, not nature. But the word of our Lord, and those who are associated with the word, endure forever. — Commentary on Isaiah Origen of Alexandria : And [Christ] commanded all the multitudes to sit down on the grass because of what is said in Isaiah, "All flesh is grass." That is to say, he commanded them to subjugate the flesh and to keep in subjection "the mind of the flesh," so that one might be able to partake of the loaves that Jesus blesses. — COMMENTARY ON Matthew 11:3 Philoxenus of Mabbug : And again in another place the same prophet saith, "He said to me, Cry. And I said, What shall I cry? All flesh is grass, and all the glory thereof is like the grass of the field". Yea, "like the grass" and like the herb which drieth up before the sun, which when once its natural juiciness and moisture have dried up neither the rain nor all the watering of the fountains can make grow green again, even so became the nation which was dead to all the vivification of the Spirit, and like grass and straw it became dry and withered by reason of the noonday heat of error, and by the hotness of evil things. The soul dieth without the remembrance of God, and when it dieth all its discretion dieth therewith, and all its emotions of thought of heavenly things are annihilated therefrom. — 13 Ascetic Discourses, Discourse 1 -- Prologue
