2 Thessalonians 2:6-9
“And now ye know that which restrains, to the end that he may be revealed in his own season. For the mystery of lawlessness does already work: only there is one that restrains now, until he be taken out of the way. And then shall be revealed the lawless one, whom the Lord Jesus shall slay with the breath of His mouth, and bring to nought by the manifestation of His coming: even he whose coming is according to the working of Satan.”
One may naturally enquire, what is that which withholds, and after that would know, why Paul expresses it so obscurely. What then is it that withholds, that is, hinders him from being revealed? Some indeed say, the grace of the Spirit, but others the Roman empire, to whom I most of all accede. Wherefore? Because if he meant to say the Spirit, he would not have spoken obscurely, but plainly, that even now the grace of the Spirit, that is the gifts, withhold him. And otherwise he ought now to have come, if he was about to come when the gifts ceased; for they have long since ceased. But because he said this of the Roman empire, he naturally glanced at it, and speaks covertly and darkly. For he did not wish to bring upon himself superfluous enmities, and useless dangers. For if he had said that after a little while the Roman empire would be dissolved, they would immediately have even overwhelmed him, as a pestilent person, and all the faithful, as living and warring to this end. And he did not say that it will be quickly, although he is always saying it— but what? “that he may be revealed in his own season,” he says,
“For the mystery of lawlessness does already work.” He speaks here of Nero, as if he were the type of Antichrist. For he too wished to be thought a god. And he has well said, “the mystery”; that is, it works not openly, as the other, nor without shame. For if there was found a man before that time, he means, who was not much behind Antichrist in wickedness, what wonder, if there shall now be one? But he did not also wish to point him out plainly: and this not from cowardice, but instructing us not to bring upon ourselves unnecessary enmities, when there is nothing to call for it. So indeed he also says here. “Only there is one that restrains now, until he be taken out of the way,” that is, when the Roman empire is taken out of the way, then he shall come. And naturally. For as long as the fear of this empire lasts, no one will willingly exalt himself, but when that is dissolved, he will attack the anarchy, and endeavor to seize upon the government both of man and of God. For as the kingdoms before this were destroyed, for example, that of the Medes by the Babylonians, that of the Babylonians by the Persians, that of the Persians by the Macedonians, that of the Macedonians by the Romans: so will this also be by the Antichrist, and he by Christ, and it will no longer withhold. And these things Daniel delivered to us with great clearness.
“And then,” he says, “shall be revealed the lawless one.” And what after this? The consolation is at hand. “Whom the Lord Jesus shall slay with the breath of His mouth, and bring to nought by the manifestation of His coming, even he whose coming is according to the working of Satan.”
For as fire merely coming on even before its arrival makes torpid and consumes the little animals that are afar off; so also Christ, by His commandment only, and Coming. It is enough for Him to be present, and all these things are destroyed. He will put a stop to the deceit, by only appearing. Then who is this, whose coming is after the working of Satan, “With all display all power,” but nothing true, but for deceit. “And lying wonder,” he says, that is, false, or leading to falsehood.
Ver. 10. “And with all deceit of unrighteousness for them that are perishing.”
Why then, you say, did God permit this to be? And what dispensation is this? And what is the advantage of his coming, if it takes place for the ruin of our race? Fear not, beloved, but hear Him saying, “In them that are perishing,” he has strength, who, even if he had not come, would not have believed. What then is the advantage? That these very men who are perishing will be put to silence. How? Because both if he had come, and if he had not come, they would not have believed in Christ; He comes therefore to convict them. For that they may not have occasion to say, that since Christ said that He was God—although He nowhere said this openly—but since those who came after proclaimed it, we have not believed. Because we have heard that there is One God from whom are all things, therefore we have not believed. This their pretext then Antichrist will take away. For when he comes, and comes commanding nothing good, but all things unlawful, and is yet believed from false signs alone, he will stop their mouths. For if you believe not in Christ, much more ought you not to believe in Antichrist. For the former said that He was sent from the Father, but the latter the contrary. For this reason Christ said, “I have come in My Father's name, and you receive Me not: if another shall come in his own name. him you will receive.” But we have seen signs, you say. But many and great signs were also wrought in the case of Christ; much more therefore ought ye to have believed in Him. And yet many things were predicted concerning this one, that he is the lawless one, that he is the son of perdition, that his coming is after the working of Satan. But the contrary concerning the other, that He is the Saviour, that He brings with Him unnumbered blessings.
Ver. 10, 11, 12. “For because they received not the love of the truth, that they might be saved; for this cause God will send them a working of error, that they should believe a lie: that they all might be judged who believed not the truth, but had pleasure in unrighteousness.”
“That they might be judged.” He does not say, that they might be punished; for even before this they were about to be punished; but “that they might be condemned,” that is, at the dreadful Seat of Judgment, in order that they might be without excuse. “Who believed not the truth, but had pleasure in unrighteousness.” He calls Christ, “the Love of the Truth.” “For because,” says he, “they received not the love of the truth.” For He was both, and came for the sake of both, both as loving men, and on behalf of things that were true.
“But had pleasure,” he says, “in unrighteousness.” For he came to the destruction of men and to injure them. For what will he not then work? He will change and confound all things, both by his commandments, and by the fear of him. He will be terrible in every way, from his power, from his cruelty, from his unlawful commandments.
But fear not. “In those that perish” he will have his strength. For Elijah too will then come to give confidence to the faithful, and this Christ says; “Elijah comes, and shall restore all things.” Therefore it is said, “In the spirit and power of Elijah.” For he neither wrought signs nor wonders, as Elijah did. For “John,” it is said, “did no miracle, but all things which John spoke of this Man were true.” How then was it “in the spirit and power of Elijah”? That is, he will take upon him the same ministry. As the one was the forerunner of His first Coming, so will the other be of His second and glorious Coming, and for this he is reserved. Let us not therefore fear. He has calmed the minds of the hearers. He causes them no longer to think present things dreadful but worthy of thankfulness. Wherefore he has added,
Ver. 13. “But we are bound to give thanks always to God for you, brethren beloved of the Lord, for that God chose you from the beginning unto salvation, in sanctification of the Spirit and belief of the truth.”
How unto salvation? By sanctifying you through the Spirit. For these are the things that are the efficient causes of our salvation. It is nowhere of works, nowhere of righteous deeds, but through belief of the truth. Here again, “in” is used for “through.” “And through sanctification of the Spirit,” he says,
