Type: supporting argument (off-timeline) · Assessment: weak — the reading that Tobit 6 prescribes occult magic forbidden by Scripture, so the book teaches error and cannot be canonical, does not hold on its best case. In the story the angel Raphael directs Tobias to keep a fish's heart, liver, and gall: the burnt heart-and-liver drive off the demon Asmodeus from Sarah, and the gall cures old Tobit's blindness. But Scripture itself repeatedly has God heal and deliver through ordinary or odd material instruments — clay made of spittle on a blind man's eyes (John 9:6), handkerchiefs from Paul's body that put out diseases and evil spirits (Acts 19:11–12), washing seven times in the Jordan (2 Kings 5:14), a bronze serpent on a pole (Numbers 21:8–9), blood on the doorposts that turns the destroyer aside (Exodus 12:13), even a coin in a fish's mouth (Matthew 17:27) — so the charge equivocates on "magic." The Torah bans autonomous occult manipulation — divination, necromancy, consulting familiar spirits (Deuteronomy 18:10–11) — not a remedy commanded by God's own angel against a demon and credited to God's power; the demon flees and is bound by the angel (Tobit 8:3), not by any technique of Tobias's. The Church that read Tobit took the episode reverently — Bede allegorized the fish-cure as Christ unmasking and binding the devil and the smoke as the renunciation of Satan in baptism; Ambrose treated Raphael's mission "to chase away Asmodaeus" as wholesome — not as a manual of sorcery. What survives the steelman is a narrower, true point of genre, not of error: Tobit reflects a vivid Second-Temple Jewish world of named demons and folk pharmacology (apotropaic fumigation; fish-gall as an ancient eye-remedy) more openly than any protocanonical book — texture that some readers find strange, but milieu, not a "command to use magic" that unbooks it · advanced by Matt Slick (CARM); answered by Joe Heschmeyer and Trent Horn

Here the interpretation under weight is the Protestant charge that Tobit 6 prescribes magic — an occult false teaching condemned by the Law — adduced, alongside the almsgiving and prayer-for-the-dead charges, as a doctrinal reason to deny the book a place in Scripture.
"Touching the heart and the liver, if a devil or an evil spirit trouble any, we must make a smoke thereof before the man or the woman, and the party shall be no more vexed. As for the gall, it is good to anoint a man that hath whiteness in his eyes, and he shall be healed."
— Tobit 6:7–8 (KJV/Apocrypha; the Vulgate and Douay–Rheims number the episode 6:5–9, which is the reference CARM gives).1 The Protestant apologist Matt Slick, founder of CARM (the Christian Apologetics & Research Ministry), lists this passage among the Apocrypha's disqualifying errors: "The Apocrypha contains a number of false teachings," he writes — "The command to use magic (Tobit 6:5–7). Forgiveness of sins by almsgiving (Tobit 4:11; 12:9). The offering of money for the sins of the dead (2 Maccabees 12:43–45)" — and elaborates that "we see it advocating magic where the smoke of a fish heart on a fire drives away devils," concluding that a book "full of false and unbiblical teachings… isn't inspired by God."2 The reasoning runs: the angel prescribes a fish-organ rite — fumigation to expel a demon, gall smeared on the eyes to cure blindness — which is magic; magic is forbidden by Scripture (Deuteronomy 18:10–11); a book that "commands" magic therefore teaches error and cannot be inspired. The question this page weighs is not the polemic but the interpretation behind it: is the fish-organ remedy occult magic at all, or a divinely-directed material sign of the kind Scripture uses throughout?
The proponent. The crisp popular form is Slick's at CARM, where the magic charge heads a list of "errors in the Apocrypha" meant to show the deuterocanon uninspired. It is a standard cell in the Reformation-era objection that the Apocrypha "teaches error, so reject it," the same frame that carries the almsgiving and prayer-for-the-dead charges weighed on their own pages. The adversaries. Catholic respondents — Joe Heschmeyer (Shameless Popery) and Trent Horn — answer that the charge "betrays a… failure to understand the difference between miracles and magic": one "can't just call miracles you don't like 'magic,'" since Scripture is full of God working healing and deliverance through material means, and the remedy in Tobit is angel-commanded and God-effected, not an occult art performed by Tobias.3
God heals and delivers through material instruments all over the canon. The single move the charge depends on — "a physical thing produces a spiritual effect, therefore magic" — would condemn a swathe of undisputed Scripture if pressed consistently. Jesus "spat on the ground, and made clay of the spittle, and… anointed the eyes of the blind man with the clay" (John 9:6) — spittle-mud on the eyes, the near-twin of gall on the eyes. From Paul's body "were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them" (Acts 19:11–12) — cloth that both heals and expels demons, the very pairing CARM finds damning in Tobit. Naaman dips "seven times in Jordan… and he was clean" (2 Kings 5:14); the plague-bitten Israelite who "beheld the serpent of brass… lived" (Numbers 21:8–9); the blood on the doorpost so that "when I see the blood, I will pass over you" (Exodus 12:13) — a material sign that turns the destroying angel aside, exactly the function of Tobit's smoke against Asmodeus; and, with a fish no less, Peter is sent to "take up the fish that first cometh up; and when thou hast opened his mouth, thou shalt find a piece of money" (Matthew 17:27). On the logic of the charge each of these is "magic"; since none is, the proof-text proves too much.4
What the Torah actually forbids is the opposite of what Tobit narrates. Deuteronomy's prohibition is of autonomous occult power — "any one that… useth divination, or an observer of times, or an enchanter, or a witch, or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer" (Deuteronomy 18:10–11): the manipulation of hidden forces, the conjuring and consulting of spirits, apart from and against God. Tobit's remedy is the inverse on every count. It is prescribed by God's own angel, Raphael, sent in answer to prayer (Tobit 3:16–17; 12:14–15); its power is ascribed to God, not to a technique; and the demon does not obey Tobias — it flees the smoke and is then bound by the angel, "he fled into the utmost parts of Egypt, and the angel bound him" (Tobit 8:3). No spirit is summoned, consulted, or commanded by the human actor; an evil spirit is repelled and shackled by a holy one. That is exorcism and healing under divine direction, the category Scripture commends, not the divination it bans.5
The Church that received Tobit read the episode as sacred, not occult. The Fathers and medievals who used the book did not flinch at the fish-organ remedy as sorcery; they read it as type and sign. Bede's whole Commentary on Tobit turns the scene into a figure of redemption: the Lord "took hold of the gill of the huge fish… because by breaking the power of the devil" he rescued his own; the burnt heart-and-liver that drive off the demon are the renunciation of "Satan and all his works… and then to confess the faith of the Holy Trinity for the remission of sins," the demon "expelled through the water of baptism"; the gall that opens blind eyes is the Lord revealing "how great is the malice of the ancient serpent." Ambrose, expounding the faithful watch-dog of Tobit's journey, takes for granted that Raphael was sent "to chase away Asmodaeus and to strengthen the conjugal bond… for with the grace of a mindful affection, the demon is driven away." A book whose alleged occultism went unremarked by the very readers most alert to pagan magic is poorly described as "commanding" it.6
What holds — the genuine residue is one of milieu, not of error. Grant the proponent his strongest point, lest the defense overstate. Tobit really does wear its Second-Temple world on its sleeve more openly than any protocanonical book: a named demon, Asmodeus, who slays Sarah's seven bridegrooms (3:8); an apotropaic fumigation to repel him; and a gall-cure for "whiteness in the eyes" that matches the folk-pharmacology of the age, in which fish gall was a stock remedy for the eyes (Pliny catalogues the use). Some readers, ancient and modern, have found the smoking-fish detail quaint or superstitious, and it is fair to locate the book in the genre of the edifying Jewish tale, where angelic instruction, demonology, and folk medicine mingle freely. That texture is real and should be conceded, not explained away.7
What fails — the leap from that texture to "magic, therefore non-canonical." Three joints give way.
The proof-text proves too much. If a material instrument producing a spiritual effect is "magic," then John 9's spittle-mud, Acts 19's handkerchiefs, the bronze serpent, the Passover blood, Elisha's Jordan, and Peter's coin-fish are magic too — and no party will unbook the Gospels and Exodus to be rid of Tobit. A reading that condemns the protocanon along with the disputed book has misnamed the offense.
It equivocates on "magic." Scripture's actual ban (Deuteronomy 18) is on divination and the summoning or consulting of spirits — power wielded apart from God. Tobit narrates the reverse: a remedy ordered by God's angel, its efficacy God's, the demon repelled and bound by the angel, no spirit conjured or consulted by any human. To file an angel-directed exorcism under "sorcery" is to collapse the very distinction — between miracle and magic — on which the biblical prohibition rests.
Using a doctrinal objection as a canon-criterion is circular — and it screens out the wrong book. The move is the same one weighed on Tobit's companion charges: decide first that a passage "teaches error," then exclude the book for it. But whether the deuterocanon is Scripture is precisely the point in dispute, and the test, applied evenly, cuts into the protocanon (the material signs above) rather than along the canon's edge. The episode's reception — allegorized as a type of Christ and of baptism by Bede, presupposed as wholesome by Ambrose — is evidence of a book read as Scripture, not expelled for impiety.
Weak. The interpretation that Tobit 6 prescribes occult magic forbidden by the Law, so that the book teaches error and is thereby excluded from the canon, does not hold on its best available case. The fish-organ remedy is a divinely-directed material sign of exactly the kind Scripture uses throughout — clay and spittle on blind eyes, healing cloth that also expels spirits, blood that turns the destroyer aside, a coin drawn from a fish — so the charge, pressed consistently, would convict the Gospels and the Pentateuch with it; and what the Torah actually bans, the autonomous manipulation and consultation of spirits, is the opposite of a remedy commanded by God's angel, after which the demon is not obeyed but bound. What survives the steelman is the narrower and true point that Tobit displays a Second-Temple world of named demons and folk pharmacology — apotropaic fumigation, fish-gall ophthalmology — more vividly than any protocanonical book, a matter of genre and milieu that some find strange. That is a reason the book reads as the edifying Jewish tale it is; it is not a reason it cannot be Scripture, on pain of unbooking half the canon that heals the same way. (Its companion charge — that Tobit's almsgiving "purges away all sin" teaches a works-righteousness — is weighed on the almsgiving argument, there likewise assessed weak; both belong to the Tobit's alleged false teachings set, and the broader question whether such doctrinal objections can settle the canon at all is the sola scriptura meta-argument.)
Tobit 6:1–8 (KJV/Apocrypha), Wikisource: the fish "would have devoured him"; the angel bids Tobias "take the heart and the liver and the gall, and put them up safely"; and on their use, "Touching the heart and the liver, if a devil or an evil spirit trouble any, we must make a smoke thereof… and the party shall be no more vexed. As for the gall, it is good to anoint a man that hath whiteness in his eyes, and he shall be healed." The episode is numbered 6:5–9 in the Vulgate/Douay–Rheims (whence CARM's "6:5–7" citation) and the same in the Catholic enumeration at USCCB, Tobit 6.

Raphael is sent in answer to prayer and names himself "one of the seven holy angels" (Tobit 3:16–17; 12:12–15) — the remedy is angel-prescribed and God-credited, the demon repelled and bound rather than summoned or obeyed. ↩
