Hebrews 13:9

Be not carried about with divers and strange doctrines: the doctrine of Christ being immutable, it is but necessary to dehort his subjects from deserting it, which the apostle doth here; that they should not be wheeling or whirling about with an unstable and inconstant motion of judgment, faith, and practice, about such human doctrines which are vain rules to lead to God, such as are different in nature from Christ, one and the same rule, and those very numerous and various, strange and untrue, taught by false apostles and teachers, taken out of Gentilism and Judaism, and added to the Gospel by them, as necessary, together with Christ, to justification and salvation, Matthew 15:9 2 Corinthians 11:3 Ephesians 4:14 2 Thessalonians 2:10,12 1 Timothy 4:1 2 Timothy 4:3,4 2 Peter 2:1,18,19 Jude 1:12. For it is a good thing that the heart be established with grace; for the goodness of heart establishment unto God is no less than full and complete salvation of the soul, 1 Corinthians 15:58 2 Peter 3:17,18. And this is only wrought by grace, the free love of God put out in Christ, for regeneration and preservation of souls unto life eternal, carried in the simple doctrine of Christ, which is always the same, 2 Thessalonians 2:16,17 1 Peter 5:10. Not with meats; doctrines of meats and ceremonies, which are divers, and strange from Christ s, cannot make the heart agreeable to God, but only distract and divide it from him; for whatsoever is not in and from Christ, is strange to God, and abhorred by him, Galatians 5:2 Colossians 2:18,19,23 2 Timothy 2:16 James 1:8. Which have not profited them that have been occupied therein: those who did converse in these various and strange doctrines, professing and constantly practising them, observed times, and meats, and ceremonies, have not been profited by them; for being carnal and eartidy, they could not justify them as to their state God-ward, nor could they renew or sanctify their souls, nor yield any advantage to their spiritual life; and being perishing, could not profit to the attaining of eternal life, Romans 14:17,18; compare 1 Corinthians 6:13.
