For neither have we used, at any time, the speech of flattery, as you know; nor taken an occasion of covetousness, God is witness:

“It therefore follows, that every one of those who undertake to promote the good of their neighbours, ought to consider whether he has betaken himself to teaching rashly and out of rivalry to any; if his communication of the word is out of vainglory; if the only reward he reaps is the salvation of those who hear, and if he speaks not in order to win favour: if so, he who speaks by writings escapes the reproach of mercenary motives. "For neither at any time used we flattering words, as ye know," says the apostle, "nor a cloak of covetousness. God is witness. Nor of men sought we glory, neither of you, nor yet of others, when we might have been burdensome as the apostles of Christ. But we were gentle among you, even as a nurse cherisheth her children."”

“"For neither at any time were we found using words of flattery, as ye know, nor a cloak of covetousness, God is witness; nor seeking glory of men, neither from you, nor from others, when we might have been burdensome, as Apostles of Christ." For "neither at any time," he says, "were we found using words of flattery"; that is, we did not flatter, which is the part of deceivers, who wish to get possession and to domineer. No one can say that we flattered in order to rule, nor that we had recourse to it for the sake of wealth. Of this, which was manifest, he afterwards calls them to be witnesses. "Whether we flattered," he says, "ye know." But as to what was uncertain, namely, whether it were in the way of covetousness, he calls God to witness. "Nor seeking glory of men, neither from you, nor from others, when we might have been burdensome, as Apostles of Christ"; that is, not seeking after honors either, nor boasting ourselves, nor requiring attendance of guards. And yet even if we had done this, we should have done nothing out of character. For if persons sent forth by kings are nevertheless in honor, much more might we be. And he has not said, that "we were dishonored," nor that "we did not enjoy honors," which would have been to reproach them, but "we did not seek them." We therefore, who, when we might have sought them, sought them not, even when the preaching required it, how should we do anything for the sake of glory? And yet even if we had sought them, not even in that case would there have been any blame. For it is fit that those men who are sent forth from God, as ambassadors now coming from heaven, should enjoy great honor. But with an excess of forbearance we do none of these things, that we may stop the mouths of the adversaries. And it cannot be said, that to you we act thus, but not so others.”

“Above he commended them because they received the word of God in tribulations; here he commends them because they did not withdraw from him on account of tribulations. And concerning this he does three things: first he recalls their tribulations; second he shows what remedy he applied for them, in chapter III, at the words "for which cause"; third, why, at the words "because now we live." But because he had said above, concerning them, that the apostle's entrance toward their conversion was reported by all, therefore he first treats of his own entrance; second, of their conversion, at "therefore we also give thanks." Concerning the first he does three things: first he recalls his own constancy, which he had before he came to them; second, the sincerity of the teaching by which he converted them, at "for our exhortation"; third, the sincerity of his conduct with those converted, at "for you." Again, the first is divided into two: first he sets forth the tribulations which he suffered before he came to them; second, how he did not lose confidence on this account, at "we had confidence." He says therefore: I say that he announces our entrance, which you also know, that it was not vain, etc., that is, light, but difficult, because it was through many tribulations. Or "not vain," that is, empty, but full. Gen. 1:2: the earth was void and empty, etc. Or "not vain," that is, unstable, but firm. Phil. 2:17: I have not run in vain, nor labored in vain. But we suffered bodily sufferings before. Prov. 19:11: the teaching of a man is known through patience. Ps. 91:15: they shall be well enduring, that they may proclaim. Likewise spiritual [sufferings], because on this account he was afflicted with insults in Philippi, where on account of the healing of the pythoness he suffered tribulations. And this city is of Macedonia. Nor yet on account of these things was the confidence of preaching extinguished. Is. 12:2: behold, God is my savior, I will act with confidence, and I will not fear. And this confidence was to preach to you the Gospel of God in much solicitude concerning your conversion. Rom. 12:8: he who is over others, with solicitude. II Cor. 11:28: besides those things that are from without, my daily pressure, the solicitude of all the churches. Then, when he says "exhortation," he shows the sincerity of his preaching. And concerning this he does two things: first he proves the sincerity of his teaching; second he explains certain things he had said, at "not as to men." Concerning the first he does two things: first he excludes the corruption of the teaching; second he sets down the sincerity, at "but as approved." Now teaching is corrupted either on account of the matter which is taught, or on account of the intention of the one teaching. On account of the first, teaching is corrupted in two ways, namely either through error, as one teaching that salvation is through Christ together with the legal observances. II Tim. 3:13: evil men and seducers shall grow worse, erring, and sending others into error. Therefore he says: "for our exhortation is not," as that of some, "of error." Or on account of uncleanness, as those who say that one ought to give oneself over to pleasures, which teaching is from a certain Nicolaus, who permitted promiscuous marriages, sharing his wife with another; therefore he says, "nor of uncleanness." Apoc. 2:20: you permit the woman Jezebel, who calls herself a prophetess, to teach and seduce my servants to fornicate, and to eat of things sacrificed to idols, etc. Job 6:30: you shall not find iniquity in my tongue. Likewise, the exhortation is not in guile as that of some, who, although they speak the truth, nevertheless have a corrupt intention, because they seek not the profit of their hearers nor the honor of God, but their own honor. Against which he says, "nor in guile." Jer. 9:8: their tongue is a wounding arrow, it has spoken guile, etc. His preaching, therefore, is not corrupt, but sincere. Now a thing is sincere which preserves its own nature. But preaching is then sincere, when someone teaches with that same tenor and end with which Christ taught. And therefore he says, "but as approved," that is, we speak in that manner and with that intention with which God chose and approved us to preach the Gospel. Gal. 2:7: the Gospel of the uncircumcision was entrusted to me, as that of the circumcision to Peter. Acts 9:15: this man is a vessel of election to me, to carry my name before the Gentiles, and kings, and the sons of Israel. Then, when he says "not as to men," etc., he shows that his preaching is not in guile. First excluding that on account of which it might seem to be deceitful; second he makes it clear through a sign, at "nor at any time"; third through a cause, at "nor on occasion." On account of the first he says: my preaching is not as pleasing men, namely, finally. Ps. 52:6: the bones of those who please men have been scattered. Gal. 1:10: if I pleased men, I would not be the servant of Christ. Sometimes, however, they ought to wish to please men for the glory of God, that preaching may bear more fruit, as is said I Cor. 10:33: I please all men in all things, etc. But God, etc. Prov. 16:2: all the ways of man are open to his eyes. Now the sign of this is that we did not flatter, speaking to them pleasing things. Is. 30:10: speak to us pleasing things, see for us errors, etc. Prov. 24:28: do not flatter anyone with your lips, etc. And he shows the same thing through a cause. For on account of two things does someone seek to please men, namely either for the sake of benefits, or for the sake of glory. But this he excludes here, and first, the first, saying, "nor were we," etc. Because we avoid not only flattery, but also every occasion of avarice. I Tim. 6:5: supposing gain to be godliness. Jer. 6:15: for from the least even to the greatest, all are devoted to avarice. Second, the second, at "nor seeking glory from you nor from others," concerning the teaching, since we might have gloried and received — rather, to be a burden, because they owed him glory and support; whence he says, "since we could." And he calls it a burden, because those preaching to them perversely sought these things from them beyond measure. Is. 3:14: for you have devoured my vineyard, etc. Then, when he says "but we became," etc., he makes clear these two things: first, that he does not seek human glory; second, that neither [does he seek] occasion for avarice, at "for you remember." Concerning the first he does two things: for first he shows his humility; second, under a likeness, he shows his solicitude, at "as if a nurse." He sets down, therefore, the first, saying that "we became little ones," etc., that is, humble. Ecclus. 32:1: have they made you a ruler? Do not be lifted up, but be among them as one of them. This he shows in a likeness, saying "as if a nurse," who, namely, condescends to an infant, speaking to it with stammering, that the child may learn to speak, and in gestures also condescends to it. I Cor. 9:22: I have become all things to all. I Cor. 3:1: as to little ones in Christ, I gave you milk to drink, not food. Even souls. John 10:11: the good shepherd gives his soul for his sheep, etc. Because most dear, etc. II Cor. 12:15: but I will most gladly spend, and be spent myself, for your souls, etc. Then, when he says "for you remember," he shows, second, what he had said above, namely, likewise, "nor by occasion of avarice," because we took nothing from you, but from labor, because "of labor," etc. And some indeed labor, but with comfort; but we did not, but with toil. Therefore he says "of our labor," not for the exercise of the body, but with fatigue. Whence he says "and of fatigue." Some also labor by day, but we, "night and day." For by this he wished to restrain the false [preachers], who received too much, and on account of the idle among them. I Cor. 4:12: we labor, working with our own hands, etc. Then, when he says "for you are," he sets forth the purity of his conduct, and first, how holy, with regard to life; second, how solicitous, with regard to teaching, at "how each one." He says therefore: you know how holily, that is, purely. Lev. 11:44 and 19:2: be holy, because I am holy. Justly, with regard to one's neighbor. Titus 2:12: let us live soberly, and justly, and piously in this age. Without complaint, to you who have believed, that is, from the time you believed, doing nothing whereby anyone could scandalize each one of you individually. Note that individual preaching sometimes avails much. As a father. I Cor. 4:15: in Christ Jesus, through the Gospel, I have begotten you. Beseeching. Philem. 8: having much confidence in Christ Jesus to command you what pertains to the matter, on account of charity I rather beg. And consoling, through gentle words. Against which it is said, Ezek. 34:4: with austerity you commanded them, with power. Is. 61:2: that I might console all who mourn, and grant consolation to those who mourn in Sion. And what did you preach? That worthily, that is, that your conduct might be such as befits the ministers of Christ. Col. 1:10: that you walk worthily of God, pleasing him in all things. Of God, who, etc. Wis. 6:21: therefore the desire of wisdom leads to the everlasting kingdom.”

“For neither at any time used we flattering words,.... To introduce them into the affections, and gain the esteem and good will of men; they did not in their ministry deliver such things as flattered men with a good opinion of themselves: they did not preach up the purity of human nature, but on the contrary the doctrine of original sin, the imputation of Adam's transgression to his posterity, and the corruption of all human nature; they asserted the universal pollution of it, of all men, and of all the powers and faculties of their souls, that they are all under the power and dominion of sin, are involved in the guilt of it, and are all guilty before God, and liable to everlasting wrath and punishment; and that unless they repented of their sins and believed in Christ, they would perish eternally; thus they dealt roundly and freely with men's consciences, and plainly, openly, and faithfully told them their case as it was: nor did they cry up the power of man's free will, which would have been grateful to Jews and Gentiles; but they declared the reverse, they asserted the weakness and impotency of man, to anything that is spiritually good; and represented him as a weak and strengthless creature, and unable to do anything, even to think a good thought of himself; and ascribed all that a man is, or has, or does, that is good, to the grace and power of God, who works in him both to will and to do: nor did they plead for the sufficiency of man's righteousness to justify him before God, a doctrine very pleasing to human nature; but, on the contrary, they gave out that there was none righteous, no, not one of the sons of Adam, in and of themselves, or by virtue of any righteousness of their own; so far from it that they were full of all unrighteousness, and were not capable of working out a righteousness, or of attaining to the righteousness of the law; that what they did pretend to was not a justifying righteousness, and would give no right and title to eternal glory; and that the righteousness of Christ was the only righteousness, by which a man could be justified from all things, and in which he could be found safe. They did not blend and mix their doctrine to suit with the tastes of different men, but with all sincerity and plainness preached the truth, as it is in Jesus; they did not connive at the sins of men, cry Peace, Peace, when there was none, or sow pillows under their armholes, or promise them life, though they should not return from their wicked way; but they with great freedom inveighed against the sins of men, and exhorted them to repentance and reformation, as well as to faith in Christ for pardon and righteousness; nor did they wink at the sins of professors, or of one another, the Apostle Paul withstood Peter to the face because he was to be blamed; and when they praised men for their gifts and graces, and the exercise of them, they took care to ascribe them to the grace of God, and give him the glory, and prevent men from boasting in themselves; in short, they acted the reverse of the false teachers, who had men's persons in admiration because of advantage, and by good words and fair speeches deceived the hearts of the simple; but so did not the apostles of Christ, no, never, not "at any time": when they first came to Thessalonica during their stay there, either in public or in private: and though this was true of any other time and place, yet here must be confined to this, since the apostle appeals to this church for the truth of what he said, as ye know; for flattering words may be discerned; a flatterer is known by his words; though in general such is the weakness of human nature, that men love to be flattered, though they know they are: nor a cloak of covetousness; or "an occasion of" it, they did not take the opportunity or advantage by the ministry of the word, to indulge a covetous disposition, or to amass wealth and riches to themselves; or an "excuse" for covetousness, which covetous men are never at a loss to make, always pretending one thing or another to hide and cover their evil; but the apostles made no excuses, nor used any cloak, nor needed any to cover their covetousness, because they had not the thing; they did not pretend one thing and mean another; they did not, as the false apostles did, pretend to serve Christ, preach his Gospel, seek the glory of God and the good of souls, and mean themselves, and design their own worldly advantage; they did not make these a "pretence" for covetousness, they sincerely served Christ, faithfully preached his Gospel, truly sought the glory of God, and were heartily concerned for the good of souls without any mercenary and selfish views; for the truth of which they could appeal to the heart searching and rein-trying God, as the apostle here does, saying, God is witness; which is properly an oath, a solemn appeal to God; for since covetousness is an internal and secret sin, and may be so coloured and disguised as not easily to be discerned, as flattering words may, the apostle therefore calls God to witness the truth of what he had said.”

“Flattering words - Though we proclaimed the Gospel or glad tidings, yet we showed that without holiness none should see the Lord. Ye know - That while we preached the whole Gospel we never gave any countenance to sin. For a cloak of covetousness - We did not seek temporal emolument; nor did we preach the Gospel for a cloak to our covetousness: God is witness that we did not; we sought you, not yours. Hear this, ye that preach the Gospel! Can ye call God to witness that in preaching it ye have no end in view by your ministry but his glory in the salvation of souls? Or do ye enter into the priesthood for a morsel of bread, or for what is ominously and impiously called a living, a benefice? In better days your place and office were called a cure of souls; what care have you for the souls of them by whose labors you are in general more than sufficiently supported? Is it your study, your earnest labor, to bring sinners to God; to preach among your heathen parishioners the unsearchable riches of Christ? But I should speak to the thousands who have no parishes, but who have their chapels, their congregations, pew and seat rents, etc., etc. Is it for the sake of these that ye have entered or continue in the Gospel ministry? Is God witness that, in all these things, ye have no cloak of covetousness? Happy is the man who can say so, whether he has the provision which the law of the land allows him, or whether he lives on the free-will offerings of the people. The faithful laborer is worthy of his hire; for the ox that treads out the corn should not be muzzled; and they that preach the Gospel should live, not riot, by the Gospel. But wo to that man who enters into the labor for the sake of the hire! he knows not Christ; and how can he preach him?”
