Matthew Poole and continuators on 1 Thessalonians 5:21

21 Prove all things , hold fast that which is good .

This duty relates to the former; as they were to attend upon prophesyings so to exercise a discerning judgment about what was prophesied. For all things is not to be taken here universally, but for Doctrines and Opinions in Religion which were delivered by the Prophets. The same which the Apostle Iohn requires, beleive not every spirit but try the spirits, &c. [non-Latin text not transcribed], and its the same word there which in this Text we read prove; alluding to Gold or other Mettals which are tryed in the Fire, or by a touch-stone, as some think. And though there was a peculiar gift of discerning of Spirits, 1 Cor. 12.10. yet it is the duty of every Christian to try mens Spirits and Doctrines whether from God or no. The Apostle speaks here to the Saints in general, and so doth the Apostle St. Iohn, 1 Iohn 4.1. And mens Doctrines are to be judged of by the Scriptures as the standard of Truth, as the Bereans were commended for searching the Scriptures about the Apostles Doctrine, Act. 17.11. and the Apostle prayes for the Philippians that they might discern things that differ, Phil. 1.10. and if they had not yet attained it as they ought, yet he prays that they might, and not be alwayes, babes, but such as the Apostle speaks of, who have their senses exercised in the discerning of good and evil, Heb. 5. 13, 14. the people are to look upon them as their guides and leaders, as they are called Heb. 13.7.17. and such as are to go before them in the searching and dispensing of truth, yet because the best are but infallible, they ought to try their Doctrine by the rule of Truth. Which is that judgment of discretion which Protestants allow to the people in their disputes with the Papists against their Doctrine of Infallibility, and implicit Faith, which grounds the peoples Faith upon the Authority of Men, which ought to rest upon the authority of God. As we ought not easily to reject the authority and Faith of the Church, so not to believe with a blind Faith, or obey with a blind obedience.

The good here meant is Truth, which is an intellectual good, the contrary to which is Error, which is a mental evil. When we have proved mens Doctrines and Opinions, what we find agreeable to the Scriptures of Truth we ought to hold fast. And though all Truth hath a goodness in it, yet especially divine Truth, and the Doctrine of the Gospel, which the Apopostle calls, That good thing committed to Timothy, 2 Tim. 1.14. It is good with respect to the soul, and so better then any bodily good, and good that refers to eternity, and so better then any temporal good. Now this good we are to hold fast. To hold it fast against adversaries and all opposition as some understand the word, to hold it as with both hands, against seducing Doctrine, Satans Temptations, and the Worlds Persecution. The same word is used concerning the good ground that held fast the seed of the Word, Luk. 8.15. So 1 Cor. 11.2. we are to retain the Truth, but not detain it, as the heathen are said to do, Rom. 1.18. where we find also the same word as in the Text. It is a duty much prest by the Apostles in their Epistles to the Saints and Churches that had received the Gospel that they would hold fast, 2 Tim. 1.13. Tit. 1.9. Heb. 4.14. Rev. 2.13▪ 25, and 3.3. And there is holding fast the Truth, as well in Practise as Opinion, and which may be the ground of the name formerly given to such as opposed the Errors of Antichrist before the word Protestant was known, call'd Fast-men.
