12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
The mouth of the Son of God is a sharp sword because “the Word of God is living and active, sharper than any two-edged sword.” … The metaphor is especially appropriate, since he did not come to bring peace on earth—that is, on the things which are corporeal and perceived by the senses—but a sword. And since he cuts, so to speak, the harmful association of soul and body that the soul may give itself to the Spirit, which wars against the flesh, and become a friend of God. This is why, according to the prophetic word, he has a mouth which is a “sword” or “like a sharp sword.”
Jesus endured the cross, disregarding the shame, and therefore is seated at the right hand of God. And those who imitate him by disregarding the shame shall sit with him and rule in the heavens with him, who came not to bring peace upon the earth but upon the souls of his followers and to bring a sword upon the earth. Since “the Word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and spirit, of joints and marrow, and discerning the thoughts and intentions of the heart,” this word above all now bestows on our souls the prize of that peace which surpasses all understanding, which he left to his apostles. And it brings a sword between the earthly image and the heavenly in order that when he receives our heavenly image we may be made fully heavenly, if we are worthy not to be cut in two.
And Scripture calls by the name of “sword” the Word which has the power of trying and of discerning thoughts and which “extends even to the division of soul and spirit, of joints and marrow.” … Every soul at the time of the passion was subjected to a sort of test, as it were, according to the words of the Lord, who said, “You will all fall away because of me.” Simeon prophesies concerning Mary that, standing beside the cross and looking at what was happening and hearing his words—even after the testimony of Gabriel, after the secret knowledge of her divine conception, after the great showing of miracles—“Even you will flee,” he says, “a certain perplexity about your soul.” For the Lord must taste of death for the sake of all, and, being made a propitiation for the world, he must justify all people in his blood. Therefore, some doubt will touch even you yourself who have been taught from above concerning the Lord. That is the sword. “That the thoughts of many hearts may be revealed,” meaning that, after the scandal which happened at the cross of Christ to both the disciples and to Mary herself, some swift healing will follow from the Lord, confirming their hearts in their faith in him. Thus we see that even Peter, after having stumbled, clung more firmly to his faith in Christ. What was human, therefore, was proved unsound in order that the power of the Lord might be manifested.
So when the fear of divine power returns to the perception of the soul, then we blush, then we desire to hide, then being placed in the thoughts of our sins, we are found in the midst of the tree of paradise where we sinned, desiring to hide, and thinking that God does not seek the hidden things. But the searcher of hearts and thoughts, penetrating even to the division of the soul, says, "Adam, where are you?"
In the next place, lest hearing the words "after the same example," thou shouldest think that the punishment is the same, hear what he adds; "For the Word of God is quick and powerful, and sharper than any two-edged sword, and pierceth even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart." In these words he shows that He, the Word of God, wrought the former things also, and lives, and has not been quenched.
Do not then when hearing the Word, think of it lightly. For "He is sharper," he says, "than a sword." Observe His condescension; and hence consider why the prophets also needed to speak of saber and bow and sword. "If ye turn not," it is said, "He will whet His sword, He hath bent His bow and made it ready." (Ps. vii. 12.) For if now, after so long a time, and after their being perfected, He cannot smite down by the name of the Word alone, but needs these expressions in order to show the superiority arising from the comparison of the Gospel with the law: much more then of old.
"Piercing," he says, "even to the dividing asunder of soul and spirit." What is this? He hinted at something more fearful. Either that He divides the spirit from the soul, or that He pierces even through them disembodied, not as a sword through bodies only. Here he shows, that the soul also is punished, and that it thoroughly searches out the most inward things, piercing wholly through the whole man.
"And is a discerner of the thoughts and intents of the heart, neither is there any creature that is not manifest in His sight." In these words most of all he terrified them. For do not (he says) be confident if ye still stand fast in the Faith, but without full assurance. He judges the inner heart, for there He passes through, both punishing and searching out.
For lest on hearing the things that belong to the soul we should grow negligent, he adds also what concerns the body. For then it is as a king, when his officers are guilty of some great fault, first strips them (say) of their command, and after depriving them of their belt, and their rank, and their herald, then punishes them: so also in this case the sword of the Spirit works.
Then, lest any think that they will simply be deprived of rest only, he adds also the punishment, saying, "For the Word of God is quick, and powerful; and sharper than any two-edged sword, and pierceth even to the dividing asunder of soul and spirit, and of the joints and marrow: and is a discerner of the thoughts and intents of the heart." Here he is speaking of Hell and of punishment. "It pierceth" (he says) into the secrets of our heart, and cutteth asunder the soul. Here it is not the failing of carcasses nor, as there, the being deprived of a country, but of a heavenly kingdom; and being delivered to an everlasting hell, and to undying punishment and vengeance.
He says, “division of soul and spirit.” The soul has a special feeling for the body, but the grace of the Holy Spirit draws against the body to the heavenly things.
He used the phrase “laid bare to the eyes of him” as a metaphor from sacrificed beasts, which lie completely mute, the slaughter doing away with their life, and along with their life their cries. In similar manner, he is saying, when we also are judged, we behold everything done by us in ungodly or lawless fashion, whereas we receive the sentence of punishment in silence, realizing as we do its justice.
John who had been exiled by the Emperor Marcion, said, ‘One day we went into Syria to see Poemen for we wanted to ask him about hardness of heart. But he did not know Greek and we did not have an interpreter. When he saw we were embarrassed, he began to speak in Greek saying, ‘The nature of water is soft, the nature of stone is hard; but if a bottle is hung above a stone letting water drip down, it wears away the stone. It is like that with the word of God; it is soft and our heart is hard, but if a man hears the word of God often, it will break open his heart to the fear of God.’
“The word of God is … sharper than any two-edged sword.” Now the holy depth of divine Scripture is expressed in such common language that everyone immediately takes it in. But buried within it are hidden senses of truth, so that the vital meaning must be most carefully sought out. What contributes most of all to our understanding that it is really divine is the fact that ignorant persons are known to have been able to explain most subtle things, and mortal humans eternal things, but only when filled with the divine Spirit.
"For the word of God is living." It gradually shows that Christ alone was the one who acted in what happened concerning the children of Israel. For it is living, he says, and will live forever. But lest they think that those who sin and provoke Christ are only frustrated by the earth as the ancients were, he adds a more terrible deed.
"sharper than any two-edged sword." As those who did not hear the speech might fear something more terrible, it expresses what has been said, adapting examples that are among us: for it could not be understood in any other way than what is said, cutting from both sides with any sword.
"piercing to the division of soul and spirit." He says something fearful: either that the spirit separates from the soul, and leaves it desolate of the holiness that the Lord in the gospel called division; (for just as a king, when a ruler sins, is stripped of his belt and his office beforehand, and then punished; so here too the spiritual dignity is first taken away from the person, then he is punished;) or that it even reaches the incorporeal themselves.
The holy Cyril certainly received in a certain place: piercing to the division of soul and spirit: He says that the preaching concerning God divides and distinguishes the parts of the soul, making them receptive and capable of the things heard. That it also reaches them, he says, of the incorporeal beings, and punishes the soul. That it works a division of soul and spirit. It is indeed fearful.
In another way.
The division that the Gospels threaten, the Fathers understood as the complete abandonment of the Holy Spirit. Therefore, I think it is now a day that causes the separation of the Holy Spirit, and it removes itself from the soul, after which all good things will subsequently follow and be taken away.
"of joints and marrow." So that, having heard the things of the soul, they do not become careless, as if the punishment were unclear, having spoken of the incorporeal, he also speaks of the corporeal; for the more visible things strike with greater fear.
"and discerning the thoughts." To distinguish and examine the very thoughts themselves, and the invisible concepts of the heart. Here the divinity of the Word is shown; for it is God who examines, that is, who tests and knows the thoughts; he says "God searches the hearts and kidneys." (Jer. 17:10).
Do you not shudder when you hear God each day saying to you through the whole of the divine Scripture, “Let no evil speech come out of your mouth”? For truly I say to you for any idle word you will give an account, and for every cup of cold water you will receive a reward. Have you not heard that God is the judge of the “thoughts and intentions of the heart”? What does it say? “He who looks at a woman with desire has already committed adultery with her in his heart.” Do you not see how he who looks with desire upon someone is considered an adulterer? Know then, surely, that those who strongly desire wealth are considered greedy, even if they have acquired nothing at all. Those who strive for many costly foods are gluttons, even if because of poverty they survive on only bread and water. They are sexually immoral who imagine many defiling encounters, even if they never look at another person. So too is it with those who say in their heart, “This has gone badly and become unreasonable” and “Why has this happened?” or “Why has that not happened?” Let them not be deceived, they are slanderers and will be judged as those who condemn, even though not a word comes out of their mouths nor does anyone hear them.
