“If equanimity be the contention, you have Lycurgus choosing death by self-starvation, because the Lacons had made some emendation of his laws: the Christian, even when he is condemned, gives thanks. If the comparison be made in regard to trustworthiness, Anaxagoras denied the deposit of his enemies: the Christian is noted for his fidelity even among those who are not of his religion.”

“For no one is going to turn away from sin and start behaving righteously unless he thinks about what he is doing. Not until he has been straightened out by practicing godly behavior will he actually possess the reward of faith: the crown of righteousness that Paul possessed, having fought the good fight. That crown is laid up not just for Paul but for all who are like him in this respect. This sort of meditation and exercise in godliness should be familiar to us, as it was to the saints of old. It should be especially so in the season when the divine word calls upon us to keep the feast. For what, after all, is the feast but continual worship of God, recognition of godliness and unceasing prayer all done from the heart in full agreement with each other? St. Paul, wanting us to be so inclined, urges us, "Always rejoice, pray without ceasing, give thanks in all things."”

“For such meditation and exercise in godliness, being at all times the habit of the saints, is urgent on us at the present time, when the divine word desires us to keep the feast with them if we are in this disposition. For what else is the feast, but the constant worship of God, and the recognition of godliness, and unceasing prayers from the whole heart with agreement? So Paul wishing us to be ever in this disposition, commands, saying, 'Rejoice evermore; pray without ceasing; in everything give thanks.' Not therefore separately, but unitedly and collectively, let us all keep the feast together, as the prophet exhorts, saying, 'O come, let us rejoice in the Lord; let us make a joyful noise unto God our Saviour.' Who then is so negligent, or who so disobedient to the divine voice, as not to leave everything, and run to the general and common assembly of the feast? which is not in one place only, for not one place alone keeps the feast; but 'into all the earth their song has gone forth, and to the ends of the world their words.' And the sacrifice is not offered in one place, but 'in every nation, incense and a pure sacrifice is offered unto God.' So when in like manner from all in every place, praise and prayer shall ascend to the gracious and good Father, when the whole Catholic Church which is in every place, with gladness and rejoicing, celebrates together the same worship to God, when all men in common send up a song of praise and say, Amen; how blessed will it not be, my brethren! who will not, at that time, be engaged, praying rightly?”

“Then, because he [David] had been delivered from great danger, he sent up this prayer of thanksgiving to God who had rescued him. "I will bless the Lord at all times." Having escaped death, as if he were setting up norms for his life, he molded his soul to an exact manner of living, so that he ceased at no time from praise but referred the beginning of affairs, great and small, to God. "I will not think," he says, "that anything was done through my diligence nor happened through spontaneous chance, but, 'I will bless the Lord at all times,' not only in prosperity of life, but also in precarious times." The apostle, learning from this, says, "Rejoice always. Pray without ceasing. In all things give thanks."”

John Chrysostom Patristic
A.D. 347–407
“"Pray without ceasing; In every thing giving thanks: for this is the will of God." Always to give thanks, this is a mark of a philosophic soul. Hast thou suffered any evil? But if thou wilt, it is no evil. Give thanks to God, and the evil is changed into good. Say thou also as Job said, "Blessed be the name of the Lord for ever." (Job i. 21) For tell me, what such great thing hast thou suffered? Has disease befallen thee? Yet it is nothing strange. For our body is mortal, and liable to suffer. Has a want of possessions overtaken thee? But these also are things to be acquired, and again to be lost, and that abide here. But is it plots and false accusations of enemies? But it is not we that are injured by these, but they who are the authors of them. "For the soul," he says, "that sinneth, itself shall also die." (Ezek. xviii. 4) And he has not sinned who suffers the evil, but he who has done the evil.”

“Most appropriately have we all this day sung together, "Blessed be the Lord God of Israel, who only does wondrous things."For marvelous, and beyond all expectation, are the things which have happened. A whole city, and so great a population, when just about to be overwhelmed—to sink under the waves, and to be utterly and instantly destroyed—he has entirely rescued from shipwreck in a single moment of time! Let us give thanks, then, not only that God has calmed the tempest but that he permitted it to take place. Not only did he rescue us from shipwreck, but he allowed us to fall into such distress and permitted such an extreme peril to hang over us. Thus also Paul bids us "in every thing give thanks." But when he says, "In every thing give thanks," he means not only in our deliverance from evils but also at the time when we suffer those evils.”

“Above he showed how subjects ought to conduct themselves toward their prelates; here he shows the converse. And concerning this he does two things: first he teaches how prelates ought to conduct themselves toward subject priests; second, generally, how they ought to conduct themselves toward all, at the place "see that no one." But it should be known that the care of prelates ought to tend to two things, namely to drawing others back from sins, and to guarding themselves. As to the first, the Apostle says three things. For subjects can suffer defect in three ways: first in act, second in will, third in power. In act, when they burst forth into an act of sin, and then they are to be corrected. And although this holds for every sin, yet they are especially to be corrected concerning the sin of restlessness. And therefore he says "rebuke the unruly." 2 Thess. 3:7: "we were not unruly among you." Ecclesiasticus 19:17: "rebuke your neighbor before you threaten, and give place to fear." In will, when one does not undertake great things, because he is cast down on account of adversities and preceding sins. Hence he says "comfort the fainthearted." The fainthearted is one not having courage for great things, fearing lest he fail. Isaiah 35:4: "say to the fainthearted: take courage and do not fear." Job 4:4: "your hands have strengthened the wavering," etc. In power, when they either sin from weakness, or are weakened in a good act, and these are to be cherished. Hence he says "support," namely by cherishing in the bowels of charity, "the weak," whose power is feeble, either for resisting evils or for doing good. Romans 15:1: "we who are stronger ought to bear the weaknesses of the weak." But the prelate ought to guard himself from defect of whatever kind, and especially from impatience, because he himself carries the whole weight of the multitude. Numbers 11:14: "I cannot alone bear this whole multitude, because it is heavy for me," etc. And therefore he says "be patient toward all." Proverbs 19:11: "the teaching of a man is known through patience." Ps. 91:15: "they will be well patient, that they may proclaim." Then when he says "see that no one," he shows generally how they should conduct themselves toward all. And concerning this he does two things: first he shows how all ought to conduct themselves in certain matters; second, what in all matters, at "but all things." Concerning the first he does three things: first he shows how they ought to conduct themselves toward the neighbor; second, how they should conduct themselves in the things that pertain to God, at "rejoice always"; third, how they should conduct themselves toward his gifts, at "do not [quench] the spirit." As to the neighbor, they ought to conduct themselves so as not to inflict evils on him, and so as to strive to do him good. Hence he says: I said above in particular, but now I say in general, let no one... evil, etc. Ps.: "if I have returned evils to those who repaid me." But on the contrary: vengeance is often sought before a judge. I respond. Just as a moral act is taken according to the intention of the end, so the intention toward two things can be: either toward the evil of that person, such that it rests there, and this is unlawful, because it comes from the rancor of vengeance; or toward the good of correction, or of justice and the preservation of the commonwealth, and thus he does not render evil for evil, but good, namely his correction. As to the second he says "but always what is good," etc. And he says "pursue," not "do": because you ought to take from yourself the occasion of doing good to your neighbor, and not wait for him to give you the occasion of doing good to him. Hence Ps. 33:15: "seek peace, and pursue it." Romans 12:21: "do not be conquered by evil," namely so that you are drawn by it to do evil, "but conquer evil with good," by drawing it back to good. Gal., last chapter: "while we have time, let us do good to all." Then when he says "rejoice always," he shows how they ought to conduct themselves with regard to God, toward whom three things must be had. First, to rejoice in him; hence he says "rejoice always," namely in God, because whatever evil may occur is incomparable to the good, which is God. And therefore let no evil interrupt that; hence he says "rejoice always." Second, "pray" for benefits to be received, at "pray without ceasing." Luke 18:1: "one must always pray, and never fail." But how can this be? I respond. It must be said that this can be in three ways. First, that he always prays who does not omit the appointed hours. A similar thing is found in 2 Kings 9:7: "you shall eat bread at my table always." Second, thus: "always," that is, "pray continually," but then prayer is taken for the effect of prayer. For prayer is the interpretation or unfolding of desire, because when I desire something, then I seek it by praying. Hence prayer is also a petition for fitting things from God, and therefore desire has the force of prayer. Ps. 9:38: "the Lord has heard the desire of the poor." All things therefore that we do proceed from desire. Therefore prayer remains virtually in the good things we do, because the good things we do proceed from good desire. The Gloss: "he does not cease to pray, who does not cease to do good." Third, as to the cause of prayer, namely by giving alms. In the Lives of the Fathers: "he always prays who gives alms, because he who has received alms prays for you, even while you sleep." Likewise, third, to pray for benefits to be received and to give thanks for those received; therefore he says "in all things," namely in good things and in adverse things, "give thanks." Romans 8:28: "for those who love God, all things work together unto good." Colossians 2:7: "abounding in him in thanksgiving." Philippians 4:6: "with thanksgiving. For this is the will," etc. 1 Timothy 2:4: "who wills all men to be saved, and to come to the knowledge of the truth." Then when he says "do not [quench] the spirit," etc., he shows how they should conduct themselves toward the gifts of God. And first, that they not impede them; second, that they not despise them, at "prophecies." Now the Holy Spirit is a divine person, incorruptible and eternal, hence in his substance he cannot be extinguished. But nevertheless someone is said to extinguish the spirit, in one way, by extinguishing his fervor, either in himself or in another. Romans 12:11: "fervent in spirit." For when someone wills to do something good from the fervor of the Holy Spirit, or also when some good movement arises, and he himself impedes it, he extinguishes the Holy Spirit. Acts 7:51: "you have always resisted the Holy Spirit." In another way, by sinning mortally. For the Holy Spirit in himself always lives, but in us he lives when he makes us live in him; but when someone sins mortally, the Holy Spirit does not live in him. Wisdom 1:5: "for the Holy Spirit of discipline will flee the deceitful," etc. In a third way, by hiding it, as if he were to say: if you have the gift of the Holy Spirit, use it for the benefit of your neighbors. Ecclesiasticus 20:32: "hidden wisdom and unseen treasure, what use is there in either?" Matthew 5:15: "no one lights a lamp and puts it under a bushel," etc. "Do not despise prophecies." For some among these were endowed with the spirit of prophecy, who were reckoned by these others as insane. 1 Corinthians 14:1: "be zealous for spiritual things, but rather that you may prophesy." Or "prophecies," that is, divine teaching. For those expounding divine teaching are called prophets; as if he were to say: do not despise the words of God and the preachings. Jeremiah 20:8: "the word of the Lord has become a reproach and a derision all the day." Then when he says "but test all things," he shows how they should conduct themselves toward all things, and it is one point, that in all things they use discretion. Romans 12:1: "your reasonable service." In this matter there ought to be diligent examination, choice of the good, rejection of the bad. As to the first he says "do not despise prophecies," yet "test all things," namely those that are doubtful. For manifest things do not need examination. 1 John 4:1: "do not believe every spirit." Job 12:8: "does not the ear discern words?" As to the second he says "hold fast what is good." Galatians 4:18: "but be zealous for good, in a good thing, always." As to the third he says "abstain from every appearance of evil." Isaiah 7:15: "that he may know to refuse the evil and choose the good." And he says "appearance," because we ought also to avoid even those things which have the likeness of malice, which namely we could not observe before men without scandal to them. Then when he says "but he himself," he adds a prayer, and concerning this he does three things: first he prays for them; second he gives hope of being heard; third he gives special admonitions. He says therefore: thus I admonish, but it avails nothing unless God gives grace. Hence "may the God of peace himself sanctify you." Leviticus 21:8: "I am the Lord, who sanctifies you," etc. "In every part," that is, that you may be wholly holy. And this "that [your] whole [spirit]," etc. For on the occasion of these words some said that in man the spirit is one thing and the soul another, positing two souls in man, one which animates, the other which reasons. And these have been condemned in ecclesiastical teachings. Hence it should be known that these do not differ according to essence, but according to power. For in our soul there are certain powers which are acts of bodily organs, as are the powers of the sensitive part. There are others, which are not acts of such organs, but are abstracted from them, as are the powers of the intellective part. And these are called "spirit," as being immaterial and separated in some way from the body, inasmuch as they are not acts of the body, and they are also called "mind." Ephesians 4:23: "be renewed in the spirit of your mind." But insofar as it animates, it is called "soul," because this is proper to it. And Paul here speaks properly. For three things concur in sinning: reason, sensuality, and the execution of the body. He wishes therefore that there be sin in none of these. Not in reason; hence he says "that [your] spirit," that is, your mind, "may be kept whole." For in every sin reason is corrupted, according as every evil man is ignorant. Likewise, nor in sensuality, hence he says "soul." Likewise, nor in body; and therefore he says "and body." But this happens thus, when it is kept immune from sin. And he says "without blame," not "without sin," which belongs to Christ alone; but to be without blame belongs also to others, who, even if they commit venial sins, do not nevertheless commit grave ones, and ones by which the neighbor is scandalized. Luke 1:6: "walking in all the commandments and justifications of the Lord without blame." And he adds "at the coming," etc., namely by persevering until the end of life. Or "whole spirit" refers to the gift of the Holy Spirit, as if he were to say: may the gift of the Holy Spirit, which you have, be whole. Then when he says "faithful," etc., he gives hope of being heard; as if he were to say: as I hope, so it will be, because "he also who has called [you] will do [it]," that is, will fulfill it. Ps. 144:13: "the Lord is faithful in all his words," etc. Romans 8:30: "whom he called, these he also justified," etc. Lastly he appends familiar admonitions: namely prayer, at "pray"; likewise mutual peace, at "greet all the brothers with a holy kiss," not a treacherous one, like Judas, Matthew 26:49, nor a lustful one, like the lustful woman, Proverbs 7:10. "That it be read," etc. For he feared lest the prelates, on account of certain things that were here, might conceal it. Proverbs 11:26: "he who hides grain will be cursed among the peoples," etc. Lastly he concludes the epistle with a salutation.”

“Quench not the spirit. By which is meant, not the person of the Spirit, but either the graces of the spirit, which may be compared to light, and fire, and heat, to which the allusion is in the text; such as faith, which is a light in the soul, a seeing of the Son, and an evidence of things not seen; and love, which gives a vehement flame, which many waters cannot quench; and zeal, which is the boiling up of love, the fervency of it; and spiritual knowledge, which is also light, and of an increasing nature, and are all graces of the spirit: and though these cannot be totally extinguished, and utterly put out and lost, yet they may be greatly damped; the light of faith may become dim; and the flame of love be abated, and that wax cold; the heat of zeal may pass into lukewarmness, and an indifference of spirit; and the light of knowledge seem to decline instead of increasing; and all through indulging some sin or sins, by keeping ill company, and by neglecting the ordinances of God, prayer, preaching, and other institutions of the Gospel; wherefore such an exhortation is necessary to quicken saints, and stir them up to the use of those means, whereby those graces are cherished and preserved in their lively exercise; though rather the gifts of the Spirit are intended. The extraordinary gifts of the Spirit, bestowed on the apostles at the day of Pentecost, are represented under the symbol of fire, to which perhaps the apostle may here have respect; and the more ordinary gifts of the Spirit are such as are to be stirred up, as coals of fire are stirred up, in order that they may burn, and shine the brighter, and give both light and heat, Ti2 1:6 and which may be said to be quenched, when they are neglected, and lie by as useless; when they are wrapped up in a napkin, or hid in the earth; or when men are restrained from the use of them; or when the use of them is not attended to, or is brought into contempt, and the exercise of them rendered useless and unprofitable, as much as in them lies. And even private persons may quench the Spirit of God, his gifts of light and knowledge, when they hold the truth in unrighteousness, imprison it, and conceal it, and do not publicly profess it as they ought. and which may be said to be quenched, when they are neglected, and lie by as useless; when they are wrapped up in a napkin, or hid in the earth; or when men are restrained from the use of them; or when the use of them is not attended to, or is brought into contempt, and the exercise of them rendered useless and unprofitable, as much as in them lies. And even private persons may quench the Spirit of God, his gifts of light and knowledge, when they hold the truth in unrighteousness, imprison it, and conceal it, and do not publicly profess it as they ought. 1 Thessalonians 5:20 th1 5:20 th1 5:20 th1 5:20Despise not prophesyings. Or "prophecies"; the prophecies of the Old Testament concerning the first coming of Christ, concerning his person, office, and work, his obedience, sufferings, and death, his resurrection from the dead, ascension and session at God's right hand; for though all these are fulfilled, yet they have still their usefulness; for by comparing these with facts, the perfections of God, his omniscience, truth, faithfulness, wisdom, &c. are demonstrated, the authority of the Scriptures established, the truths of the Gospel illustrated and confirmed, and faith strengthened; and besides, there are many prophecies which regard things to be done, and yet to be done under the Gospel dispensation, and therefore should not be set at nought, but highly valued and esteemed: also the predictions of Christ concerning his own sufferings and death, and resurrection from the dead, and what would befall his disciples afterwards, with many things relating to the destruction of Jerusalem, his second coming, and the end of the world, these should be had in great esteem; nor should what the apostles foretold concerning the rise of antichrist, the man of sin, and the apostasy of the latter days, and the whole book of the Revelations, which is no other than a prophecy of the state of the church, from the times of the apostles to the end of the world, be treated with neglect and contempt, but should be seriously considered, and diligently searched and inquired into. Yea, the prophecies of private men, such as Agabus, and others, in the apostle's time, and in later ages, are not to be slighted; though instances of this kind are rare in our times, and things of this nature should not be precipitantly, and without care, given into: but rather prophesyings here intend the explanation of Scripture, and the preaching of the word, and particularly by persons who had not the gift of tongues, and therefore men were apt to despise them; see Co1 13:2. Just as in our days, if persons have not had a liberal education, and do not understand Latin, Greek, and Hebrew, though they have ministerial gifts, and are capable of explaining the word to edification and comfort, yet are set at nought and rejected, which should not be.”

“In every thing give thanks - For this reason, that all things work together for good to them that love God; therefore, every occurrence may be a subject of gratitude and thankfulness. While ye live to God, prosperity and adversity will be equally helpful to you. For this is the will of God - That ye should be always happy; that ye should ever be in the spirit of prayer; and that ye should profit by every occurrence in life, and be continually grateful and obedient; for gratitude and obedience are inseparably connected.”

“In every thing--even what seems adverse: for nothing is really so (compare Rom 8:28; Eph 5:20). See Christ's example (Mat 15:36; Mat 26:27; Luk 10:21; Joh 11:41). this--That ye should "rejoice evermore, pray without ceasing, (and) in every thing give thanks," "is the will of God in Christ Jesus (as the Mediator and Revealer of that will, observed by those who are in Christ by faith, compare Phi 3:14) concerning you." God's will is the believer's law. LACHMANN rightly reads commas at the end of the three precepts (Th1 5:16-18), making "this" refer to all three.”
