John Cassian — Commentary on Scripture

Genesis 3:22

And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:

And how will that statement of the Lord stand, after the sin of the first man: “Behold, Adam is become like one of us, knowing good and evil?” For he must not to be thought to have been such before the sin that he was wholly ignorant of good. Otherwise, it must be admitted that he was created like an irrational and senseless animal; and this is quite absurd and foreign to the Catholic faith. No, rather, according to the pronouncement of the most wise Solomon, “God made man right,” that is, to enjoy continually the knowledge of good alone. But they sought many thoughts. So they were made, as it was said, “knowing good and evil.” After the fall, therefore, Adam conceived a knowledge of evil, which he did not have. But he did not lose the knowledge of good, which he did have.

Genesis 5:21-24

And Enoch lived sixty and five years, and begat Methuselah:

The mind is so caught up in this way that the hearing no longer takes in the voices outside and images of the passerby no longer come to sight and the eye no longer sees the mounds confronting it or the gigantic objects rising up against it. No one will possess the truth and the power of all this unless he has direct experience to teach him. The Lord will have turned the eyes of his heart away from everything of the here and now, and he will think of these as not transitory so much as already gone, smoke scattered into nothing. He walks with God, like Enoch. He is gone from a human way of life, from human concerns. He is no longer to be found amid the vanity of this present world. The text of Genesis relates that this actually happened to Enoch in the body: “Enoch walked with God and was not to be found because God had taken him away.” The apostle says, “Because of his faith, Enoch was taken up so that he did not have to encounter death.”

Genesis 6:1-4

And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,

As long then as there continued that separation of the lines between them, the seed of Seth, as it sprang from an excellent root, was by reason of its sanctity termed "angels of God," or as some copies have it "sons of God;" and on the contrary the others by reason of their own and their fathers' wickedness and their earthly deeds were termed "children of men." Though then there was up to this time that holy and salutary separation between them, yet after this the sons of Seth who were the sons of God saw the daughters of those who were born of the line of Cain, and inflamed with the desire for their beauty took to themselves from them wives who taught their husbands the wickedness of their fathers, and at once led them astray from their innate holiness and the single-mindedness of their forefathers...From these sons of Seth then and daughters of Cain, as we have said, there were I born still worse children who became mighty hunters, violent and most fierce men who were termed giants by reason of the size of their bodies and their cruelty and wickedness. For these first began to hara…

For these first began to harass their neighbours and to practise pillaging among men, getting their living rather by rapine than by being contented with the sweat and labour of toil, and their wickedness increased to such a pitch that the world could only be purified by the flood and deluge.

Habakkuk 2:1

I will stand upon my watch, and set me upon the tower, and will watch to see what he will say unto me, and what I shall answer when I am reproved.

If someone perseveres continually in this watchfulness, therefore, he will effectively bring to pass what is quite plainly expressed by the prophet Habakkuk: “I will stand on my watch and go upon my rock, and I will look out to see what he will say to me and what I should reply to him who reproaches me.” The laboriousness and difficulty of this is very clearly proved by the experiences of those who dwell in the desert of Calamus or Porphyrion.

Hebrews 7:3

Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.

Listen, you heretic, to the passage you have garbled: hear in full and completely, what you quoted mutilated and hacked about. The apostle wants to make clear to every one the twofold birth of God. In order to show how the Lord was born [both] in the Godhead and in flesh, he says, “Without father, without mother.” The one belongs to the birth of divinity, the other to that of the flesh. For, as he was begotten in his divine nature “without mother,” so he is in the body “without father.” Though he is neither without father nor without mother, we must believe in him “without father and without mother.” For, if you regard him as begotten of the Father, he is without mother. If you regard him as born of his mother, he is without father. And so in each of these births he has one [parent]: in both [births] together he is without each. For, the birth of divinity had no need of mother; and for the birth of his body, he was himself sufficient, without a father. Therefore says the apostle “Without [father or] mother, without genealogy.”

Hebrews 9:1-5

Then verily the first covenant had also ordinances of divine service, and a worldly sanctuary.

If you wish to achieve true knowledge of Scripture, you must hurry to achieve unshakable humility of heart. This is what will lead you not to the knowledge that puffs a person up but to the love which illuminates through the achievement of love. It is impossible for the unclean of heart to acquire the gift of spiritual knowledge. Therefore be very careful that your zeal for scriptural reading does not, because of empty pretentiousness, prove to be a cause of perdition instead of being for you the source of knowledgeable light and of the endless glory promised to the one enlightened by knowledge.Then, having banished all worldly concerns and thoughts, strive in every way to devote yourself constantly to the sacred reading, so that continuous meditation will seep into your soul and, as it were, will shape it to its image. Somehow it will form that “ark” of the Scriptures and will contain the two stone tablets, that is, the perpetual strength of the two Testaments. There will be the golden urn that is a pure and unstained memory and which will preserve firmly within itself the everlasti…

Somehow it will form that “ark” of the Scriptures and will contain the two stone tablets, that is, the perpetual strength of the two Testaments. There will be the golden urn that is a pure and unstained memory and which will preserve firmly within itself the everlasting manna, that is, the eternal, heavenly sweetness of spiritual meanings and of that bread which belongs to the angels. The branch of Aaron is the saving standard of our exalted and true high priest, Jesus Christ. It leafs out forever in the greenness of undying memory. This is the branch that was cut from the root of Jesse and which after death comes more truly alive.
Now all of these things are covered over by the two cherubim, that is, by the plentitude of historical and spiritual lore. “Cherubim” means knowledge in abundance. They provide an everlasting protection for that which appeases God, namely, the calm of your heart, and they will cast a shadow of protection against all the attacks of malignant spirits.
And thus your soul will not only become the ark of God’s testament, but it will be carried forward into a priestly realm. And, by its unfailing love of purity, its concentration upon the disciplines of the spirit, it will implement the priestly command imposed by the lawgiver, “He will not emerge from the holy place, lest he profane the sanctuary of God.” That is, he will not depart from his own heart, where the Lord promised to live continuously when he said, “I will live and walk among them.”

Hosea 2:6-7

Therefore, behold, I will hedge up thy way with thorns, and make a wall, that she shall not find her paths.

Through the prophet Hosea the divine word well expressed God’s concern and providence toward us. He speaks of the image of Jerusalem as a prostitute who is drawn with wicked ardor to the worship of idols. She says, “I will go after my lovers, who give me my bread and my water, my wool and my flax, my oil and my drink.” The divine condescension replies, with a view to her salvation and not to her will, “Behold, I will hedge in her paths with thorns, and I will hedge her in with a wall, and she will not find her ways. And she will pursue her lovers and not lay hold of them, and she will seek them and not find them, and she will say, ‘I will return to my first husband, because then it was better for me than it is now.’ ”

Hosea 2:19-20

And I will betroth thee unto me for ever; yea, I will betroth thee unto me in righteousness, and in judgment, and in lovingkindness, and in mercies.

The sixth degree of chastity is that he not be deluded by the alluring images of women even when asleep. For although we do not believe that this delusion is sinful, nonetheless it is an indication of a desire that is still deeply ingrained. It is evident that this delusion can occur in a number of ways. For each person is tempted, even while asleep, according to how he behaves and thinks while awake. Those who have known sexual intercourse are led astray in one way, those who have had no part in union with a woman in another way. The latter are usually disturbed by simpler and purer dreams, such that they can be cleansed more easily and with less effort. But the former are deceived by filthier and more explicit images until, gradually and according to the measure of chastity for which each is struggling, even the mind that has fallen asleep learns to hate what it used to find pleasurable, and, through the prophet, the Lord grants it what is promised to brave men as the highest reward for their labors: “I will destroy the bow and the sword and war from your land, and I will make you…

Hosea 4:12

My people ask counsel at their stocks, and their staff declareth unto them: for the spirit of whoredoms hath caused them to err, and they have gone a whoring from under their God.

“It is written in the law: ‘You shall not commit fornication.’ ” This is kept in a beneficial way according to the simple sound of the letter by the person who is still entangled in the passions of fleshly impurity. It is necessarily observed in spiritual fashion, however, by one who has already left behind this filthy behavior and impure disposition. This person also rejects not only all idolatrous ceremonies but also every superstition of the Gentiles and the observance of auguries and omens, and of all signs and days and times, and is certainly not engaged in the divination of particular words or names. [This] befouls the wholesomeness of our faith. Jerusalem is said to have been debauched by this fornication, having fornicated “on every high hill and under every green tree.” And the Lord, rebuking [Jerusalem], says by the prophet: “Let the astrologers stand and save you, who gazed on the stars and counted the months, so that from them they might announce the things that are to happen to you.” Concerning this fornication the Lord reproaches them elsewhere when he says, “The spirit…

Hosea 7:9

Strangers have devoured his strength, and he knoweth it not: yea, gray hairs are here and there upon him, yet he knoweth not.

Not content with these words, the blessed Anthony entered upon a wider field of discussion, and he said, “This way of life and this most lukewarm condition not only causes you the loss that I have spoken of, even though you yourself may not feel it now. You may even somehow say in keeping with a sentence from Proverbs: ‘They strike me, but I did not grieve, and they mocked me, but I was unaware.’ And remember what is said by the prophet Hosea: ‘Aliens devoured his strength, and he himself did not even recognize it.’ ”

Hosea 7:13

Woe unto them! for they have fled from me: destruction unto them! because they have transgressed against me: though I have redeemed them, yet they have spoken lies against me.

If [birds] do not hold to the narrow path with cautious and careful restraint as they go their way, making their airy progress through the void, thanks to their marvelous skill, the earth, which is as it were the natural mooring for everyone and the most solid and safe foundation for all, becomes for them a present and manifest danger—not because its nature is changed but because they fall precipitously upon it by the weight of their body. Similarly, the unwearying goodness of God and his unchangeable substance itself certainly hurt no one, but we ourselves bring death upon ourselves by falling from the heights to the depths. For this very fall means death for the one who falls. For it is said: “Woe to them, for they have departed from me. They shall be destroyed, for they have transgressed against me.”

Hosea 10:12

Sow to yourselves in righteousness, reap in mercy; break up your fallow ground: for it is time to seek the LORD, till he come and rain righteousness upon you.

Therefore, if you are concerned to attain to the light of spiritual knowledge not by the vice of empty boastfulness but by the grace of correction, you are first inflamed with desire for that blessedness about which it is said, “Blessed are the pure of heart, for they shall see God.” [Thus] you may also attain to that about which the angel said to Daniel: “Those who are learned shall shine like the splendor of the firmament, and those who instruct many in righteousness like the stars forever.” And in another prophet: “Enlighten yourselves with the light of knowledge while there is time.”

Hosea 14:8

Ephraim shall say, What have I to do any more with idols? I have heard him, and observed him: I am like a green fir tree. From me is thy fruit found.

Holy people have never testified that they attained by their effort the right path to travel on as they made their way to the increase and perfection of virtue. Rather they would plead to the Lord and say, “Direct me in your truth,” and, “Direct my way in your sight.” Another one declares that it is not by faith alone but also by experience and, as it were, in the very nature of things that he has seized upon this, [saying], “I have known, O Lord, that a person’s way is not in him, nor is it in a man to walk and to direct his own steps.” And the Lord himself says to Israel, “I will direct him like a green fir tree; from me your fruit has been found.”

Isaiah 1:19

If ye be willing and obedient, ye shall eat the good of the land:

Who understands clearly how the sum of salvation is attributed to our will?…What does this all mean except that in each of these cases both the grace of God and our freedom of will are affirmed, since even by his own activity a person can occasionally be brought to a desire for virtue, but he always needs to be helped by the Lord.

Isaiah 1:20

But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.

Moreover, we know that even holy people have been given over bodily to Satan or to great sufferings on account of some slight sins. For the divine clemency does not permit the least blemish or stain to be found in them on the day of judgment. According to the words of the prophet, which are in fact God’s, he purges away all the dross of their uncleanness in the present so that he may bring them to eternity like fire-tried gold or silver, in need of no penal cleansing.

Isaiah 1:25-26

And I will turn my hand upon thee, and purely purge away thy dross, and take away all thy tin:

This occurs for the sake of cleansing, however, when he humbles his righteous ones for their small and as it were insignificant sins or because of their proud purity, giving them over to various trials in order to purge away now all the unclean thoughts … which he sees have collected in their inmost being, and in order to submit them like pure gold to the judgment to come, permitting nothing to remain in them that the searching fire of judgment might afterwards find to purge with penal torment.

Isaiah 9:7

Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.

Surely the coming of God in the flesh could not remain hidden from humanity, since the prophet had openly said about him, as though to the whole human race: “behold your God,” and “this is your God,” and again “the mighty God, Father of the coming world, Prince of peace,” and “of his kingdom there will be no end.” Once God had come, however, did his coming remain hidden from those who openly confessed? Was Peter ignorant of the advent of God when he said, “You are Christ, the Son of the living God”? Did Martha not know the one in whom she believed or the meaning of what she was saying when she declared, “Lord, I believe that you are Christ, the Son of the living God who has come into the world”? Finally, was not everyone who asked him to heal diseases or to replace lost limbs or to raise the dead petitioning God’s omnipotence rather than humanity’s weakness?

Isaiah 10:14

And my hand hath found as a nest the riches of the people: and as one gathereth eggs that are left, have I gathered all the earth; and there was none that moved the wing, or opened the mouth, or peeped.

And so God, the Creator and Healer of all, knowing that pride is the cause and fountain head of evils, has been careful to heal opposites with opposites, that those things which were ruined by pride might be restored by humility. For the one says, “I will ascend into heaven,” and the other, “My soul was brought low even to the ground.” … The one says, “As eggs are gathered together which are left, so have I gathered all the earth”; the other says, “I am like a pelican of the wilderness … and am become as a sparrow dwelling alone on a roof.” … If we look at the reason for our original fall and the foundations of our salvation, and [if we] consider by whom and in what way the latter were laid and the former originated, we may learn, either through the fall of the devil, or through the example of Christ, how to avoid so terrible a death from pride.

Isaiah 11:2-3

And the spirit of the LORD shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the LORD;

About this text you should first take care to observe that Isaiah does not say that “the spirit of fear shall rest upon him” but “shall fill him.” The power of it is so abundant that if once it possesses a person in its strength, it possesses his mind to the exclusion of all else. Linked with the charity that never fails, it fills and permanently possesses the soul whom it has seized, and it cannot be lessened by the temptations of any this-worldly happiness.

Isaiah 14:13-14

For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:

And because he “loved the words of ruin,” with which he had said, “I will ascend into heaven,” and the “deceitful tongue,” with which he had said of himself, “I will be like the Most High,” and of Adam and Eve, “You shall be as gods,” therefore “shall God destroy him forever and pluck him out and remove him from his dwelling place and his root out of the land of the living.” Then “the just,” when they see his ruin, “shall fear, and shall laugh at him and say” (what may also be most justly aimed at those who trust that they can obtain the highest good without the protection and assistance of God): “Behold the man that did not make God his helper but trusted in the abundance of his riches and prevailed in his vanity.”
