George Leo Haydock, on Heb 13:9

“Be not led away with various and strange doctrines. For it is best that the heart be established with grace, not with meats; which have not profited those that walk in them.”

“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.””
