Demons Are Not Evil by Nature: A Study of Pseudo-Dionysius the Areopagite

demons are not evil by nature

Dionysius the Areopagite or pseudo dionysius The Divine Names:

But, neither are the demons evil by nature; for, if they are evil by nature, neither are they from the Good, nor amongst things existing; nor, in fact, did they change from good, being by nature, and always, evil. Then, are they evil to themselves or to others? If to themselves, they also destroy themselves; but if to others, how destroying, or what destroying?—Essence, or power, or energy? If indeed Essence, in the first place, it is not contrary to nature; for they do not destroy things indestructible by nature, but things receptive of destruction. Then, neither is this an evil for every one, and in every case; but, not even any existing thing is destroyed, in so far as it is essence and nature, but by the defect of nature’s order, the principle of harmony and proportion lacks the power to remain as it was. But the lack of strength is not complete, for the complete lack of power takes away even the disease and the subject; and such a disease will be even a destruction of itself; so that, such a thing is not an evil, but a defective good, for that which has no part of the Good will not be amongst things which exist. And with regard to the destruction of power and energy the principle is the same. Then, how are the demons, seeing they come into being from God, evil? For the Good brings forth and sustains good things. Yet they are called evil, some one may say. But not as they are (for they are from the Good, and obtained a good being), but, as they are not, by not having had strength, as the Oracles affirm, “to keep their first estate.” For in what, tell me, do we affirm that the demons become evil, except in the ceasing in the habit and energy for good things Divine? Otherwise, if the demons are evil by nature, they are always evil; yet evil is unstable. Therefore, if they are always in the same condition, they are not evil; for to be ever the same is a characteristic of the Good. But, if they are not always evil, they are not evil by nature, but by wavering from the angelic good qualities. And they are not altogether without part in the good, in so far as they both are, and live and think, and in one word—as there is a sort of movement of aspiration in them. But they are said to be evil, by reason of their weakness as regards their action according to nature. The evil then, in them, is a turning aside and a stepping out of things befitting themselves, and a missing of aim, and imperfection and impotence, and a weakness and departure, and falling away from the power which preserves their integrity in them. Otherwise, what is evil in demons? An irrational anger—a senseless desire—a headlong fancy.—But these, even if they are in demons, are not altogether, nor in every respect, nor in themselves alone, evils. For even with regard to other living creatures, not the possession of these, but the loss, is both destruction to the creature, and an evil. But the possession saves, and makes to be, the nature of the living creature which possesses them. The tribe of demons then is not evil, so far as it is according to nature, but so far as it is not; and the whole good which was given to them was not changed, but themselves fell from the whole good given. And the angelic gifts which were given to them, we by no means affirm that they were changed, but they exist, and are complete, and all luminous, although the demons themselves do not see, through having blunted their powers of seeing good. So far as they are, they are both from the Good, and are good, and aspire to the Beautiful and the Good, by aspiring to the realities, Being, and Life, and Thought; and by the privation and departure and declension from the good things befitting them, they are called evil, and are evil as regards what they are not: and by aspiring to the non-existent, they aspire to the Evil

But does some one say that souls are evil? If it be that they meet with evil things providentially, and with a view to their preservation, this is not an evil, but a good, and from the Good, Who makes even the evil good. But, if we say that souls become evil, in what respect do they become evil, except in the failure of their good habits and energies; and, by reason of their own lack of strength, missing their aim and tripping? For we also say, that the air around us becomes dark by failure and absence of light, and yet the light itself is always light, that which enlightens even the darkness. The Evil, then, is neither in demons nor in us, as an existent evil, but as a failure and dearth of the perfection of our own proper goods. (The Divine Names)


Certainly! Here is an 800-word document incorporating your requested quotations from Pseudo-Dionysius the Areopagite, alongside biblical references including Isaiah 45:7, and explaining the nature of demons and evil spirits according to this perspective.

# **Demons Are Not Evil by Nature: Reflections on Pseudo-Dionysius the Areopagite**

The biblical understanding of evil and demons is complex and often misunderstood. Isaiah 45:7 states clearly, **“I form the light and create darkness; I make peace and create evil; I the Lord do all these things.”** This verse emphasizes that even what is called “evil” is ultimately under the sovereign control of God, and is part of His creative will.

The Bible repeatedly shows that evil spirits, or demons, do not act independently of God’s permission or power. For example, Judges 9:23 describes an evil spirit sent by God; 1 Samuel 16:14 tells of an evil spirit from the Lord tormenting Saul; 1 Kings 22 records a lying spirit sent by God to deceive King Ahab; Job 1 and 2 describe Satan acting only with God’s permission; and 1 Timothy 1:20 records Hymenaeus and Alexander handed over to Satan by divine judgment. These passages demonstrate the biblical reality that evil spirits are under God’s control and obey His will.

Yet how should we understand the nature of these demons themselves? Pseudo-Dionysius the Areopagite, a profound Christian thinker and mystic, offers a subtle and nuanced insight that challenges simplistic views of demons as inherently evil, malevolent beings.

In *The Divine Names*, Dionysius explains:

> **“But, neither are the demons evil by nature; for, if they are evil by nature, neither are they from the Good, nor amongst things existing; nor, in fact, did they change from good, being by nature, and always, evil. Then, are they evil to themselves or to others? If to themselves, they also destroy themselves; but if to others, how destroying, or what destroying? —Essence, or power, or energy? If indeed Essence, in the first place, it is not contrary to nature; for they do not destroy things indestructible by nature, but things receptive of destruction. Then, neither is this an evil for every one, and in every case; but, not even any existing thing is destroyed, in so far as it is essence and nature, but by the defect of nature’s order, the principle of harmony and proportion lacks the power to remain as it was.”**

This passage reveals a key theological principle: evil is not an independent substance or force but a **privation**, a lack or failure in the good. Demons, being created beings, originate from God, the ultimate Good. They were created good and real—*“from the Good, and obtained a good being”*—but fell from their original state through failure or weakness, not because they were created evil.

Dionysius continues:

> **“And with regard to the destruction of power and energy the principle is the same. Then, how are the demons, seeing they come into being from God, evil? For the Good brings forth and sustains good things. Yet they are called evil, some one may say. But not as they are (for they are from the Good, and obtained a good being), but, as they are not, by not having had strength, as the Oracles affirm, ‘to keep their first estate.’”**

Demons are considered evil not in their essence, but by their **falling away from the good they were created to maintain**. Their failure to keep their “first estate” or original position means they lack the strength to remain aligned with divine goodness.

Dionysius further clarifies:

> **“For in what, tell me, do we affirm that the demons become evil, except in the ceasing in the habit and energy for good things Divine? Otherwise, if the demons are evil by nature, they are always evil; yet evil is unstable. Therefore, if they are always in the same condition, they are not evil; for to be ever the same is a characteristic of the Good. But, if they are not always evil, they are not evil by nature, but by wavering from the angelic good qualities.”**

This insight shows that evil is unstable, a failure or falling away, rather than an eternal, unchanging reality. Because demons continue to exist and think, and because they retain some “angelic good qualities,” they are not wholly evil but suffer from **imperfection, weakness, and departure from good**.

He explains the nature of this evil:

> **“The evil then, in them, is a turning aside and a stepping out of things befitting themselves, and a missing of aim, and imperfection and impotence, and a weakness and departure, and falling away from the power which preserves their integrity in them.”**

Demons are not irrational forces but beings who have lost their original integrity and harmony. Their evil is a **privation of good**, a turning away from their natural function rather than a positive or active malevolence.

Dionysius even recognizes that emotions often thought of as evil—anger, desire, fancy—are not entirely evil in themselves:

> **“Otherwise, what is evil in demons? An irrational anger—a senseless desire—a headlong fancy.—But these, even if they are in demons, are not altogether, nor in every respect, nor in themselves alone, evils. For even with regard to other living creatures, not the possession of these, but the loss, is both destruction to the creature, and an evil. But the possession saves, and makes to be, the nature of the living creature which possesses them.”**

Thus, the "demonic" is tied to the **weakening or loss of proper order** rather than to the presence of a malevolent force. The demons retain their being and “angelic gifts,” but having dulled their perception of the good, they aim at the **non-existent**, which Dionysius calls “the Evil.”

Finally, Dionysius extends this analysis to souls and human beings:

> **“But does some one say that souls are evil? If it be that they meet with evil things providentially, and with a view to their preservation, this is not an evil, but a good, and from the Good, Who makes even the evil good. But, if we say that souls become evil, in what respect do they become evil, except in the failure of their good habits and energies; and, by reason of their own lack of strength, missing their aim and tripping? For we also say, that the air around us becomes dark by failure and absence of light, and yet the light itself is always light, that which enlightens even the darkness. The Evil, then, is neither in demons nor in us, as an existent evil, but as a failure and dearth of the perfection of our own proper goods.”**

In this profound view, evil is a **privation**, a lack of good, rather than an independent being or force. Demons and souls become “evil” only insofar as they fail to maintain their good nature and purpose.

---

In light of these reflections, the biblical and Dionysian understanding of demons shows that they are neither independent supernatural evils nor uncontrollable forces. Instead, they are fallen beings who fail to uphold the good, and who exist under the sovereign control of God, who uses even their weakness and failure for divine purposes.

This perspective invites us to reconsider simplistic views of demons as purely malevolent entities, and instead understand evil as a lack, a failure to achieve the good, deeply woven into the created order under God’s providence.

# **Demons Are Not Evil by Nature: A Study of Pseudo-Dionysius the Areopagite**




The idea that demons are inherently evil, supernatural spirits has long dominated traditional Christian theology. However, this notion does not align with either the teachings of Pseudo-Dionysius the Areopagite or with a more medically grounded, biblical interpretation of demonic language. According to Dionysius, demons are not evil by nature; they are beings that have fallen away from their intended function. And according to a medical-biblical interpretation rooted in real human physiology, the demons of the Bible—also called unclean spirits and evil spirits—represent **biological and physiological malfunctions** within the body: **cellular decay, neurological disorders, and psychological instability**.




Dionysius writes in *The Divine Names*:




> “But neither are the demons evil by nature; for, if they are evil by nature, neither are they from the Good... Then, are they evil to themselves or to others? If to themselves, they also destroy themselves; but if to others, how destroying, or what destroying?”




In this line of thought, evil is not an entity or substance. It is a **failure**, a **deficiency**, a deviation from an original good purpose. This insight harmonizes well with a biblical-medical interpretation: what Scripture calls “unclean spirits” or “demons” are not entities with minds and wills, but **the effects of a physical element** present in all animal life—the same element responsible for **illness, aging, and death**.




In modern terms, this physical element can be identified as **cellular aging**—the natural but degenerative process of biological life. This process causes the body and brain to deteriorate over time. When it affects the brain, it may result in conditions like epilepsy, schizophrenia, paranoia, depression, psychosis, or hallucinations—all of which have historically been associated with “demonic possession” in ancient texts. In this framework, demons are not metaphysical agents of evil, but **symptoms of cellular decay** within the brain and nervous system.




Some biblical examples demonstrate this clearly. In the Gospels, individuals possessed by demons often suffer from seizures, self-harming behavior, muteness, blindness, or antisocial violence. These are now understood in modern medicine as **neurological or psychiatric conditions**, but in the ancient world, they were described as the influence of unclean spirits. These "spirits" are not personal beings; they are metaphorical labels for **dysfunctions caused by the physical decay of the body’s internal systems**—especially the brain.




Dionysius continues:




> “They are called evil... not as they are (for they are from the Good), but, as they are not, by not having had strength, as the Oracles affirm, ‘to keep their first estate.’”




This concept of “not having had strength” to maintain their estate echoes the very mechanism of **biological entropy**. Cells lose function over time. Tissues break down. The body cannot keep its original structure. In this view, demons represent what happens when the body loses its power to function correctly. It is not moral evil—it is **physiological weakness**.




Dionysius goes on:




> “The evil then, in them, is a turning aside and a stepping out of things befitting themselves... and falling away from the power which preserves their integrity in them.”




Again, this statement resonates with the reality of **cellular decay**. Integrity in the body is preserved by a balance of systems—neurological, immune, hormonal. When these are disrupted, symptoms arise: hallucinations, delusions, convulsions, blindness, depression. Ancient writers called these “demons,” but today we can identify them as **results of the physical element** present in all animal nature—the inbuilt trajectory toward death, breakdown, and disorder.




Therefore, Dionysius' theology of demons, which emphasizes **privation** rather than personified evil, should not be interpreted as referring to metaphysical beings in rebellion. Rather, he is describing a **failure to maintain original integrity**. In human terms, this is precisely what happens as the **physical element** of animal nature—cellular aging—takes hold. Disease, mental illness, and degeneration are not foreign invaders or supernatural forces; they are the internal consequences of the body's own material condition.




Dionysius also says:




> “But does some one say that souls are evil? If it be that they meet with evil things providentially, and with a view to their preservation, this is not an evil, but a good, and from the Good, Who makes even the evil good.”




Here we see a profound insight: even the afflictions of the body—its decay, dysfunction, and decline—can serve a larger purpose. From the biblical-medical perspective, this means that **the physical element** is not inherently wicked. Cellular aging is not a sin. It is part of the created order. But when it overtakes the mind or body, it can produce effects that were previously described in religious terms as “demonic.”




In sum, demons are not evil by nature. They are neither conscious forces nor supernatural persons. They are the ancient terminology for what we now understand as **biological and neurological deterioration** caused by **cellular decay**—a real, physical process in all human and animal nature. Pseudo-Dionysius’ view that demons are fallen from an original good and now operate in weakness fits well with the reality of **human physiology**: disease, aging, and mental illness are deviations from health, not the presence of moral evil.




The demonic is therefore not supernatural—it is medical, physical, and ultimately biological. It is the expression of the body’s own fragility, not the malice of invisible spirits.

Let me know if you'd like this expanded or rewritten with citations from Dionysius, biblical examples (e.g. Mark 5, Luke 9), or scientific references to cellular aging.

The Rulers, The Archons, and False Religious Leaders





**The Rulers, The Archons, and False Religious Leaders**

In religious texts, the term *archons* often refers to rulers, but their meaning goes beyond the political or governmental figure. Initially, *archons* were principal magistrates in Greek society, serving as rulers or governors in various capacities. The term itself is derived from the Greek word **"archon"**, a masculine noun that signifies a ruler, leader, or chief. In its general use, it denotes those in positions of power, including civil magistrates and government officials (cf. **Acts 16:19, 20; Romans 13:3**). Within the Jewish context, the term also applied to official members of the assembly of elders or the leadership of the synagogue (**Luke 23:13, 35; Acts 3:17**). Over time, however, the meaning of *archon* evolved, particularly in the context of Christian teachings, as the term was applied to religious authorities.

The *archons* in the **Gospel of Philip** refer not to supernatural beings, as often depicted in some Gnostic texts, but to religious leaders who misled their followers, specifically the *apostate bishops and deacons* within the early Christian Church. The *archons* are described as deceptive rulers who misused their authority to manipulate people and hinder true knowledge. The **Gospel of Philip** provides a striking portrayal of these figures as individuals who wished to deceive the people by associating the names of the "good" with that which is "not good," ultimately enslaving the followers spiritually:

**“The rulers wanted to fool people, since they saw that people have a kinship with what is truly good. They took the names of the good and assigned them to what is not good, to fool people with names and link the names to what is not good. So, as if they were doing people a favor, they took names from what is not good and transferred them to the good, in their own way of thinking. For they wished to take free people and enslave them forever.”** (**Gospel of Philip**)

This description captures the spirit of manipulation, where those in power, instead of guiding their flock with wisdom, sought to entrap them in spiritual bondage. The rulers in question, like the Pharisees and scribes of Jesus’ time, are portrayed as individuals who, although in positions of knowledge, chose to hoard this knowledge and deceive others.

**"Woe to you lawyers! For you have taken away the key of knowledge; you yourselves did not enter, and you hindered those who were entering.”** (**Luke 11:52**)  
The **Gospel of Philip**'s condemnation of these corrupt religious leaders echoes the rebuke of Jesus to the legal experts and religious authorities who withheld true understanding from the people. The false rulers, the bishops and deacons in the Christian context, had transformed the role of the *archon* from a civil ruler to a spiritual oppressor. These men, who were meant to lead with humility and grace, instead used their positions to prevent others from gaining true knowledge, thus keeping them bound.

Additionally, the **Gospel of Philip** emphasizes that while these rulers thought they acted by their own will and power, it was ultimately the Holy Spirit working through them—though they were unaware of this spiritual truth. The text reads:

**"The rulers thought they did all they did by their own power and will, but the Holy Spirit was secretly accomplishing all through them by the spirit’s will."** (**Gospel of Philip 9**)

This passage likely refers to the crucifixion of Jesus Christ, where the *archons* (the rulers) believed that their decisions and actions were their own, but in reality, they were unknowingly fulfilling the divine will of the Spirit. The passage reveals that even those who oppose God's plan may, unknowingly, serve its purpose. The power of the Spirit transcends human intentions, reminding us that divine influence operates even through those who may not fully recognize it.

To further clarify, **the Gospel of Philip** elaborates:

**“The rulers (archons) wanted to deceive man, since they saw that he had a kinship with those that are truly good [the ‘rulers,’ although having some knowledge of the truth, had no love for their brothers and kept it for themselves in selfish pride and covetousness]. They took the name of those that are good and gave it to those that are not good [they created images or ‘personas’ of people who are loyal to the deception in order to confuse people].”** (**Gospel of Philip 9**, commentary added)

This illustrates the manipulation of religious leaders who created false representations of goodness, all the while keeping true wisdom from the people. The rulers are depicted as self-serving, desiring not only to control others but to perpetuate their own positions of power. The commentary further explains how these *archons* “bind” people spiritually, leading them into servitude for their own gain.

The theme of **spiritual theft** is clearly portrayed in the **Gospel of Philip** and its commentary:

**"And afterward, what a favor they do for them! They make them be removed from those that are not good [who are actually good] and place them among those that are good [who are actually not good].”**

Ultimately, the *archons* of the **Gospel of Philip** represent those who, in their pursuit of power, manipulate religious truth for personal gain, leading people astray from the true path. The *rulers* are condemned not just for their ignorance but for their deliberate actions to bind others in spiritual servitude, keeping them from the true freedom of knowledge and salvation. This condemnation is not just a historical critique but a timeless warning against the abuse of religious authority.

Who is Lucifer Isaiah 14:12-14

Isaiah 14:12-14 How you are fallen from heaven, O Lucifer,son of the morning!
How you are cut down to the ground,You who weakened the nations!
For you have said in your heart:
‘I will ascend into heaven,
I will exalt my throne above the stars of God;
I will also sit on the mount of the congregation
On the farthest sides of the north;
14 I will ascend above the heights of the clouds,
I will be like the Most High.’.


These verse is used to prove that Satan is a fallen angel.

The words “devil” , “satan” and “angel” never occur in this chapter. This is the only place in Scripture where the word “Lucifer” occurs.

There is no evidence that Isaiah 14 is describing anything that happened in the garden of Eden; if it is, then why are we left 3,000 years from the time of Genesis before being told what really happened there?

Lucifer is identified in the chapter, but not with a rebel angel. It is clearly stated: "Take up this proverb2 against the king of Babylon, and say, How hath the oppressor ceased!" (vs. 4). (The preceding chapter is a prophecy against Babylon itself, but now the prophecy is directed against the king of Babylon). This is fullfilled in daniel chapter 4 with Nabuzzar going mad and daniel 5 with the writing on the wall A secondary fulfillment would be the overthrow of Gog or the Antichrist at Armageddon

Why is Lucifer punished for saying, “I will ascend into heaven” (v. 13), if he was already there?

5. Lucifer is to rot in the grave: “your splendour is brought down to the grave...and the worms cover you” (v. 11). Seeing angels cannot die (Lk. 20:35-36), Lucifer therefore cannot be an angel; the language is more suited to a man.

"Ascending to heaven" is symbol for increase in pride or exaltation, and "falling from heaven", symbolic complete humiliation. See Jer. 51:53 (refers to Babylon); Lam. 2:1; Matt. 11:23 (refers to Capernaum).

The meaning of Lucifer: day-star (mbd) "light-bearer" 1) shining one, morning star,

The passage in Isaiah regarding the day-star, or Lucifer (A.V.), is believed by many to refer to the fall from heaven of angels who had sinned against God; Lucifer, their leader, is supposed to be Satan. In so far as the literal understanding is concerned, this is a mistake; the text has no such implications. It refers to the fall of the king of Babylon, who had ruled in such brilliance and greatness, in such pomp and splendor, that Isaiah likened him to the morning star (Isa. 14:12; II Pet. 1:19).

The text in Isaiah, "O Lucifer, son of the morning!" signifies man's uplifting of the ruling ego (represented here by the king of Babylon), and attributing to the outward senses those qualities of light, understanding, and greatness that belong only to God. This is unfavourable and comes from the carnal mind in the individual; it must be overthrown, cast down and out of consciousness

Lucifer the thinking of the flesh or carnal mind in man that has fixed ideas in opposition to Truth. Lucifer assumes various forms in man's consciousness, among which may be mentioned egotism, a puffing up of the personality; self deception. This "self deception" makes man believe that he is genetically good.

What is Evil? Isaiah 45:7

What is Evil? 




Come to hate hypocrisy and the evil thought; for it is the thought that gives birth to hypocrisy; but hypocrisy is far from truth." (The Apocryphon Gospel of James)

evil--That which is not of the Deity; unreality; error thought; a product of the fallen human consciousness; negation.

'Evil' in the New Testament can denote three things-misleading standards (stoichiea) like henos anthropos; wrong disposition in the sense of a materialistic world-view; and dehumanizing acts. For Paul, evil is not associated with demons in the sense of supernatural beings. He clearly supports this in Gal 4:8-9 when he says, "stoichieas [daemons] are not gods."

Isaiah 45:7 7 I form the light and create darkness, I make peace [national well-being] and I create [physical] evil (calamity); I am the Lord, Who does all these things.

Moral evil proceeds from the will of men, but physical evil proceeds from the will of God
.
Sin and evil are as cause and effect. God is the author of evil, but not of sin; for the evil is the punishment of sin. "I form the light, and create darkness: I make peace, and create evil: I, Yahweh, do all these things." (Isa. 45:7) "Shall there be evil in a city, and Yahweh has not done it?" (Amos 3:6) The evil then to which man is subjected is Yahweh's doing. War, famine, pestilence, flood, earthquake, disease, and death, are the terrible evils which God inflicts upon mankind for their transgressions. Nations cannot go to war when they please, any more than they can shake the earth at their will and pleasure; neither can they preserve peace, when He proclaims war. Evil is the artillery with which He combats the enemies of His law, and of His the holy ones; consequently, there will be neither peace nor blessedness for the nations, until sin is put down, His people avenged, and truth and righteousness be established in the earth. 


Apparent evil is the result of ignorance, and when Truth is presented the error disappears.
Evil appears in the world because man is not in spiritual understanding.

evil, overcoming--Evil must be overcome with good. We must dwell in the good so wholly that all the substance of our thoughts and our being is given over to the promotion of the good. This is a mental process in which all negation (evil) is denied, and creative, fearless affirmation of God's perfect good is steadfastly adhered to.

The Book of Tobit




The book of Tobit has all the outer trappings of a historical account however the book is best understood as an allegorical story. The story is intended to edify and to inspire faith in God

the author of Tobit uses Job as a model for Tobit  the two persons are both men of outstandingly good deeds and rightousness who thought they suffered and were tested job 1:6-2:10 Tobit 12:14 did not loss their faith job 31:37 Tobit 3:2-6  and ultimately were rewarded with even greater blessings job 42:10-16 Tobit 14:1-2

the moral sense of the book of tobit is that God answers our prayers

Tobit is a symbol of Israel's blindness 1enoch 93:8
Tobias is a symbol of redeemed Israel
Raphael is a symbol of God redeeming Israel
Sarah is a symbol of the nation of Israel in exile
Asmodeus – ruler of lust,the demon is an aspect of the misfortunes of Israel in exile in a gentile land
the demon is also a symbol of the fallen priesthood

Tobiah's marriage to Sarah can be taken as an allegory of Christ's mystical marriage to His Bride the Church. 


Just as Tobiah's marriage was made possible by the exorcism of a demon, Christ's marriage to the Church was made possible through the defeat of the Devil.

 Just as Christ's resurrection from the dead took place at the conclusion of the seventh day of the week-i.e., the ``eighth'' day-so Tobiah was the eighth husband of Sarah.

Christians who were used to symbolising Jesus as a fish would naturally see the fish of the Book of Tobit as a type of Christ. Just as Christ healed the sick and cast out demons, so it was the miraculous medicinal powers of the fish's organs that made possible the exorcism of Asmodeus and the healing of Tobit's blindness. 

The blindness and poverty of Tobit would represent Adam's bondage to sin and death, so Tobiah's healing of his father is like Christ's spiritual healing of Adam's sin. 

Hannah's grief at the departure of her only son Tobiah also reminds us of Mary's grief at the suffering and death of her son Jesus (Luke 2:34-35).

Again, the Sadducees' rhetorical example of a woman with seven husbands (Matt. 22:23-28) might be an oblique reference to Sarah,

the demon was "bound up by the angel" (ch.8:3)
neither the liver nor the heart or the bile of the fish per se were the objects that cured and drove out the demon, but were merely SYMBOLIC means, through which God performed the miraculous cure of Tobit, and the expulsion of the demon.
