Saint Thomas Aquinas comments: In what has gone before the Apostle disclosed the character of his coming to them; here he indicates the character of their conversion. In treating this Paul makes two points. First, he shows that they have been perfectly converted as a result of their steadfast faith; secondly, he shows how courageously they persevered amidst tribulations (2:14). Paul first remarks upon their blessings, for which he offers thanks, and then he supplies a reason for this.
So Paul says, and, since I have carefully preached to you, as a father to his children, I therefore thank God as a father does for the welfare of his children: “No greater joy can I have than this, to bear that my children follow the truth” (3 Jn. 1:3). “With thanksgiving” (Phil. 4:6). But for what reason? For this, that when you received the word of God which you heard from us, you accepted it not as the word of men but as what it really is, the word of God. The preacher should give thanks when his preaching proves to be effective in the lives of his congregation. Paul tells them, you heard the word of God from us, that is, through us: “Let me hear what God the Lord will speak” (Ps. 85:8). “Faith comes from what is heard, and what is heard comes by the preaching of Christ (Rom. 10: 17). You accepted it, that is, you kept it firmly in your heart, not as the word of men; for the words of man are empty: “You desire proof that Christ is speaking in me” (2 Cor. 13:3). “No prophecy ever came by the impulse of man, but men moved by the Holy Spirit spoke from God” (2 Pet. 1:21). And why does he give thanks? Because the fact that you have believed, God has worked in you. “For God is at work in you, both to will and to work for his good pleasure” (Phil. 2:13). “Thou hast wrought for us all our works” (Is. 26:12).
Then when be says, for you, brethren, became imitators of the churches of God in Christ Jesus which are in Judea, he shows how courageously they persevered in the midst of tribulations; and in treating this he makes two points. First, he speaks of their trials, in which they stood firm; secondly, of the remedy he proposes to apply (2:17). Again, the first point is divided into two parts. First, Paul commends them for their patience in the face of difficulties; secondly, be reprehends those responsible for the difficulties (2:15).
Consequently, Paul says: you received the word not as the word of men, but as what it really is, the word of God, for you exposed yourselves for its sake even to death. The fact that a man dies for the sake of Christ is testimony to the fact that the words of the faith are the words of God; and, therefore, “martyrs” means the same as “witnesses.” In Judea, for it is there that the faith of Christ was first proclaimed: “For out of Zion shall go forth the law, and the word of the Lord from Jerusalem” (Is. 2:3). In addition, it was also there that the first persecution of the faith occurred, as is evident from Acts (8:1): “On that day a great persecution arose against the church in Jerusalem.” “But recall the former days when, after you were enlightened, you endured a hard struggle with sufferings” (Heb. 10:32). The Thessalonians endured similar difficulties, so Paul remarks: for you suffered the same things from your own countrymen, that is, from the incredulous Thessalonians: “And a man’s foes will be those of his own household” (Matt. 10:36).
Then when Paul observes, who killed both the Lord Jesus, he rebukes the Jews who started the persecution. First, he recalls their sin, and then the reason for the sin (2:16). In regard to the first point Paul does three things: first, he treats their sin in relation to God’s ministers; secondly, with reference to God Himself; and thirdly as relating to the entire human race.
The ministers of God are those who preach, namely, Christ, the prophets and the apostles. Preaching is performed by Christ as the one from whom the doctrine originates, by the prophets who prefigured this doctrine, and by the apostles who carry out the injunction to preach.
Paul first makes reference to Christ when he says: who killed the Lord Jesus, as is clear from Matthew (21:38): “This is the heir; come, let us kill him.” That it was the Gentiles who killed him is not a valid objection, for the Jews with their own words asked Pilate to kill him: “My heritage has become to me like a lion in the forest, she has lifted up her voice against me” (Jer. 12:8). Paul then speaks of the prophets when he mentions: and the prophets. “Which of the prophets did not your fathers persecute? And they killed those who announced beforehand the coming of the Righteous One, whom you have now betrayed and murdered” (Ac. 7:52). Paul next speaks of the apostles when he comments: and drove us out, that is, the apostles. “Beware of men, for they will deliver you up to councils, and flog you in their synagogues” (Mt. 10: 17).
Secondly, Paul mentions the sin of the Jews in its relation to God, with the words: and displease God, although they may think that through this they do a service to God, as is evident in John 16. Actually, because they do not have zeal for God in accordance with knowledge, they are not pleasing to God, since they do not act in keeping with right faith and “without faith it is impossible to please him” (Heb. 11:6); “therefore the anger of the Lord was kindled against his people, and he stretched out his hand against them and smote them” (Is. 5:25).
Thirdly, Paul considers their sin in its relation to the whole human race, when he says: and oppose all men. “His hand against every man and every man’s hand against him” (Gen. 16:12). And they are antagonistic, because they prohibit and impede the preaching to the Gentiles, and also the conversion of the Gentiles. In Acts 10 and 11 Peter is criticized for having gone to Cornelius; also in Luke 15 the elder son, the Jewish people, is disturbed because the younger son, the Gentile people, is received by the father. “Woe to him who says to a father, ‘What are you begetting”’ (Is. 45:10). “Would that all the Lord’s people were prophets” (Num. 11-29).
The reason for this sin is found in the divine permission, by which God wills that they fill up the measure of their sins. Indeed, for all things which come about, either good or bad, there is a certain measure, because nothing is infinite; and the measure of all these things is in [God’s] foreknowledge. The measure of good things is what it prepares, for “grace was given to each of us according to the measure of Christ’s gift” (Eph. 4:7); the measure of evil things, however, is what it permits, for if some are “evil, they are not as evil as they want, but as God permits. And, therefore, they live until they attain that which God permits: “Fill up, then, the measure of your fathers” (Matt. 23:32). So Paul says: so as always to fill up the measure of their sins. For after the suffering of Christ, God gave the Jews forty years to repent, but they were not converted; rather they multiplied their sins. God did not permit this to go on, so Paul states: but Gods wrath has come upon them until the end. “For great is the wrath of the Lord that is kindled against us, because our fathers have not obeyed the words of this book, to do according to all that is written concerning us (2 Kg22:13). “For great distress shall be upon the earth and wrath upon this people” (Lk. 21:23). And you should not think that this wrath shall last for one hundred years only, but until the end of the world, when all the Gentiles will have embraced [the Christian religion], and then all of Israel shall be saved, as it appears from Rom. 10, Lk. 19:44, 21:6, and Matt. 24:2: “There will not be left here one stone upon another, that will not be thrown down.”
Then when Paul says, but since we were bereft of you, brethren, for a short time, he shows the remedy that he proposed to apply for them, namely, that he will personally go to them. In regard to this he makes three points: first, be discusses his proposed visit; secondly he treats the obstacle to his visit (2:18); thirdly, he gives the reason why he wanted to go (2:19).
So Paul says: but since we were bereft of you, either on account of your tribulations, or because we were separated from you [in conversation], that is, missing the opportunity for conversation, and in person, that is, not being able to enjoy your company. Both of these things require the presence of a friend because it is consoling. But not in heart, for we are present in heart, as is evident from 1 Cor. (5:3): “For though absent in body I am present in spirit.” We endeavored the more eagerly and with great desire to see you face to face, that we may be present also in body as we are in our heart; “I have longed for many years to come to you” (Rom. 15:23). When Paul says we, he intends a plural meaning, because he writes in the name of three persons, that is, in his own name, and that of Silvanus, and of Timothy. Therefore Paul says: we wanted to come to you, all of us perhaps once, but I Paul, again and again, that is twice, as I proposed; but Satan hindered us, that is, set up obstacles, perhaps through violent winds, as in: “Four angels standing at the four corners of the earth, holding back the four winds of the earth” (Rev. 7:1).
Then when Paul says: for what is our hope, he gives the reason for his proposal. First, in regard to the future; secondly, in regard to the present (2:20). Paul says: I desire to see you and I give thanks for your blessings which are our hope; for it is on account of these blessings that we hope for rewards from God, when He shall come to render to every one according to his deeds. For the greatest reward of the preacher comes from those whom he has converted. Or joy, because their joy is the Apostle’s joy, just as their goodness is the Apostle’s goodness; for the goodness of the effect is accounted for by the goodness of the cause. Or crown of boasting, because as a result of their struggles he who encouraged them to struggle shall be decorated; for the commander who led the soldiers to combat is decorated: “He who disciplines his son will profit by him, and will boast of him among acquaintances” (Sir. 30:2). 1 ask what is this hope; is it not you? Yes, assuredly: in the future, that is, before our Lord Jesus at his coming; but also in the present, for you are, among all the faithful, our glory: I would rather die than have any one deprive me of my ground for boasting” (1 Cor. 9:15); and joy, for which reason Paul rejoices over their good fortune in the present.
