Heb 13:9

“That is, the doctrines of the [levitical] priests and their offerings. "It is well that the heart is strengthened by grace," that is, is made firm by the new gospel, not by the restrictions of the priests about food. Those who practiced this way of life obtained no profit in these rules; that is, those who observed them were not purified nor had eternal life in them.”

“"Be not carried about with divers and strange doctrines." Not "with strange doctrines" only, but neither with "divers ones." "For it is a good thing that the heart be established with grace, not with meats which have not profited them that have been occupied therein." Here he gently hints at those who introduce the observance of "meats." For by Faith all things are pure. There is need then of Faith, not of "meats."”

“"Be not carried about with divers and strange doctrines." "Strange," that is, different from those ye heard from us; "Divers" that is, of all sorts: for they have no stability, but are different one from another. For especially manifold is the doctrine of meats. "For it is a good thing that the heart be established with grace; not with meats." These are the "divers," these the "strange" doctrines: especially as Christ has said, "not that which entereth into the mouth defileth the man, but that which cometh out." (Matt. xv. 11.) And observe that he does not make bold to say this openly, but as it were by a hint. "For it is a good thing that the heart be established with grace, not with meats." Faith is all. If that establishes it, the heart stands in security. It follows that Faith establishes: consequently reasonings shake. For Faith is contrary to reasoning. "Which" (he says) "have not profited them that have been occupied therein." For what is the gain from the observance of them, tell me. Does it not rather destroy? Does it not make such an one to be under sin? If it be necessary to observe them, we must guard ourselves. "Which" (he says) "have not profited them that have been occupied therein." That is, who have always diligently kept them. There is one observance, abstaining from sin. For what profit is it, when some are so polluted, as not to be able to partake of the sacrifices? So that it did not save them at all; although they were zealous about the observances. But because they had not faith, even thus they profited nothing.”

“According to the teaching of Paul, "Those who occupied themselves with meats were not benefited by them," and not only were they deprived of any benefits, but they gathered together for their own persons loss and injury. And although the lust of the belly is not these, yet it leadeth unto them, for when the heart hath become gross through meats, straightway it driveth out from itself the remembrance of God, and when the memory of God hath departed from a man, what wickedness will he not do? and what iniquity will he be not moved to do? Even as also the prophet Moses hath taught us that through this cause the people forgot their God, and that through the lust of the belly they went forth unto idolatry, and from eating meat they were led into blasphemies, and from dainty foods they arrived at all wickedness.”

“"Various," meaning now some, now others, and from some and from others, but foreign to right doctrine. For teaching may be "various," yet not "foreign," and therefore not counterfeit. But when teachings are various, that is, from one person one thing and from another something different, then they are also "foreign," that is, foreign to the truth, and then one must be on guard. For the truth is simple and has one aim. Pay attention to the expression "do not be carried away" — he speaks as if about those frivolous people who are easily carried away here and there. Here are strange doctrines. He hints at those who introduce the Jewish attachment to foods. So, he says that by "grace," that is, by faith, we must be strengthened and fully persuaded that nothing is unclean, but to the believer all things are clean. So what is needed is faith, not the observance of foods. For "those occupied with foods," that is, those who always followed the strict observance of rules about eating, brought no benefit to the soul, since they are alien to faith and slavishly serve a useless law. And in general, he says, what benefit did they receive from the observance of foods, when they were so defiled that they could not participate in the sacrifices?”

“The use of grace ought to be manly in itself. Whence the Apostle to the Hebrews: "It is best to establish the heart with grace," he does not say the stomach. At other times you have labored to strengthen your bodies. He who wishes to have strong arms must exercise himself in works of strength. Similarly, he who wishes to have stabilizing grace must exercise himself in works of virtue.”

“From Christ, indeed, is the fruit of grace. This fruit of grace is fourfold: it consists in steadying the soul through faith, blessing it through divine love, lifting it up through hope, curbing it through divine fear. The Apostle speaks of the first: "It is good to make steadfast the heart by grace, not by foods." The Jews steadied themselves with foods.”

“After exhorting them to follow the example and manner of life of those who have departed, the Apostle now warns them to continue in their teaching. In regard to this he does two things: first, he gives the warning; secondly, the reason (v. 10). In regard to the first he does two things: first, he warns them in general; secondly, he explains the warning (v. 9b). He says, therefore: Do not be led away by diverse and strange teachings. As if to say: Thus we have said that you should imitate the faith of the apostles. Therefore, do not be led away from their teaching to any other doctrine. Here it should be noted that since truth consists in the mean, which is one, many false statements can be opposed to one truth, just as there are many extremes to one middle. Therefore, the doctrine of faith is one, because only one line can be drawn between two points. But all other doctrines are manifold, because there are many deviations from what is straight. Hence, he says, by diverse doctrines, i.e., divided: 'Their heart is divided: now they shall perish' (Hos 10:2). These are the doctrines about which he said (1 Tim. 4:1): 'Doctrines of devils, speaking lies in hypocrisy.' Furthermore, they are strange, i.e., straying from the Catholic faith. But such doctrines must not be supported by us, because 'we are not strangers and foreigners, but fellow citizens of the saints, and the domestics of God' (Eph. 2:19). Then when he says, For it is well that the heart be strengthened by grace, he explains in detail which are various and strange doctrines. Here it should be noted that in the early Church there was one error rampant, namely, that it was necessary for salvation to observe the ceremonies of the Law, which consisted especially in partaking of certain foods, such as the paschal lamb (Ex. 12) and in abstaining from certain foods, as is clear from Leviticus (chap. 12) and from other passages. Another error was that of the Nicolaitans, that it was lawful to use bodily pleasures indiscriminately. These words can be applied to both these errors, but more properly to the first. He says, therefore, Be not led away from the truth by diverse and strange doctrines: 'Be not easily moved from your sense' (2 Th. 2:2); 'I wonder that you are so soon removed from him that called you into the grace of Christ, unto another gospel' (Gal. 1:6). For God requires our heart of us: 'My son, give me your heart' (Pr. 23:26); therefore, it is well that the heart be strengthened with grace. For it should be firm and stable; against which Ps. 39 (v. 13) says: 'My heart has forsaken me.' But it is not strengthened with bodily foods, but with sanctifying grace: 'Justified freely by his grace' (Rom. 3:24) and with the redemption which is in Christ Jesus. Therefore, he says, not by foods, which have not benefited their adherents: 'The kingdom of God is not meat and drink, but justice and peace and joy in the Holy Spirit' (Rom. 14:17). Therefore, the heart is not established with moderate or superfluous use of food, but rather with God's grace: 'His heart is ready to hope in the Lord, his heart is strengthened he shall not be moved until he look over his enemies' (Ps. 111:8). But hope is an anchor stabilizing the heart: 'We have fled for refuge to hold fast the hope set before us, which we have as an anchor of the soul, sure and firm' (Heb. 6:18). And he says, which have not benefited their adherents, i.e., hope in them, because those who use them for bodily needs profit with bodily health, but those who put their entire interest in them, walk in them. These are the ones whom they do not profit unto the salvation either of soul or body: 'Shall the holy flesh take away from you your crimes, in which you have boasted?' (Jer. 11:15).”

“With various and strange doctrines. Such as the disciples of Simon Magus had begun to teach; nor with the false doctrine of those among you, who would make you subject to the ceremonies and sacrifices of the former law, which never of themselves profit those who walk in them, so as to give true sanctification, and which now are no longer obligatory. (Witham) — The grace of Jesus Christ is the true support of our hearts, and this grace is conveyed to us by means of the sacraments, especially the holy Eucharist. Hence St. Ignatius of Antioch addresses the Ephesians as follows: “Brethren, stand fast in the faith of Jesus Christ; in his passion and resurrection; breaking that one bread, which is the medicine of immortality, the antidote against death, and the means of living in God by Christ Jesus; the medicament that expels all evil.””

“about--rather, as oldest manuscripts read, "carried aside"; namely, compare Eph 4:14. divers--differing from the one faith in the one and the same Jesus Christ, as taught by them who had the rule over you (Heb 13:7). strange--foreign to the truth. doctrines--"teachings." established with grace; not with meats--not with observances of Jewish distinctions between clean and unclean meats, to which ascetic Judaizers added in Christian times the rejection of some meats, and the use of others: noticed also by Paul in Co1 8:8, Co1 8:13; Co1 6:13; Rom 14:17, an exact parallel to this verse: these are some of the "divers and strange doctrines" of the previous sentence. Christ's body offered once for all for us, is our true spiritual "meat" to "eat" (Heb 13:10), "the stay and the staff of bread" (Isa 3:1), the mean of all "grace." which have not profited--Greek, "in which they who walked were not profited"; namely, in respect to justification, perfect cleansing of the conscience, and sanctification. Compare on "walked," Act 21:21; namely, with superstitious scrupulosity, as though the worship of God in itself consisted in such legal observances.”

“"diverse and strange teachings." Paul says, do not be led astray by teachings that go beyond doctrines, neither different nor strange ones. For the doctrine itself is also recognizable; but to be carried away, as from the metaphor of those who are mad, who are carried here and there, has been said. "for it is good for the heart to be strengthened by grace." For the heart established by the grace of God will not be led astray by diverse and strange teachings, but will keep to the truth. "not by foods." Therefore, by faith, which is active through the grace of God, the heart must be strengthened, not being strengthened in regard to the observance of foods; for those who walk in these observances, that is, those who keep them, have gained nothing from them.It is said that some among them observe the food according to Jewish customs.”
