The Man of Lawlessness
2 Thessalonians 2, the restrainer and the mystery of iniquity, as the early church read it
Paul warns of a "man of sin" who exalts himself in the temple of God, held back for now by a mysterious "restrainer," and finally destroyed by Christ's appearing. The modern prophecy charts decode this into a single future world-dictator and a rebuilt Jerusalem temple. Chrysostom, sixteen centuries ago, read it differently and more soberly: the restrainer is the Roman empire, the "mystery of lawlessness" was already at work in Nero (a type of the Antichrist), the temple means "every Church," and the lawless one is undone simply by the brightness of Christ's coming. The Father in his own words below, with a plain restatement.
The Father's words are verbatim and attributed (Chrysostom, Homilies on 2 Thessalonians, NPNF, public domain; selected from the running prose, footnote apparatus omitted). The box marked "In plain terms" is our own restatement, never the Father's words.
2 Thessalonians 2:3-4 · KJV…that man of sin be revealed, the son of perdition; who opposeth and exalteth himself above all that is called God… so that he as God sitteth in the temple of God, shewing himself that he is God.
"Seated in the temple of God, not that in Jerusalem only, but also in every Church."
St. John ChrysostomRight at the verse the charts lean on hardest, Chrysostom does not require a rebuilt temple in Jerusalem. "The temple of God," he says, is "not that in Jerusalem only, but also in every Church", because since Christ, the temple of God is His people (see the letter on the Temple). The lawless usurpation is the spirit that sets itself up as God within the things of God, wherever that happens, not a single future building project.
2 Thessalonians 2:6-7 · KJVAnd now ye know what withholdeth that he might be revealed in his time. For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
"What then is it that withholdeth…? Some indeed say, the grace of the Spirit, but others the Roman empire, to whom I most of all accede… 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… 'Only there is one that restraineth 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."
St. John Chrysostom"'For the mystery of lawlessness doth already work.' He speaks here of Nero, as if he were the type of Antichrist. For he too wished to be thought a god… if there was found a man before that time… who was not much behind Antichrist in wickedness, what wonder, if there shall now be one?"
St. John ChrysostomTwo things stand out. First, the "restrainer" is, for Chrysostom and much of the early church, the Roman empire, a present political reality, and he says Paul wrote vaguely on purpose, to avoid being charged with predicting Rome's fall. Second, the "mystery of iniquity" was already working in Paul's own day, in Nero, "a type of Antichrist" who wanted to be worshipped as a god. So the lawless spirit is not parked entirely in the far future; it was active then and recurs, which is exactly how John speaks of "many antichrists" already.
2 Thessalonians 2:8 · KJVAnd then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
"'Whom the Lord Jesus shall slay with the breath of His mouth, and bring to nought by the manifestation of His 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."
St. John ChrysostomHowever fearsome the lawless one, his end is almost an anticlimax: Christ does not wage a long war against him; He destroys him "with the breath of His mouth," "by only appearing." The mere brightness of the true King's coming undoes the counterfeit. The comfort of the passage is that evil's hour is real but short, and Christ's victory needs no struggle.
Where this stands among the traditions
This is where the modern prophecy systems diverge most from the early church. The dispensational reading turns this into a single future Antichrist enthroned in a literally rebuilt Jerusalem temple, on a decoded end-times timeline. The early church, as Chrysostom shows, read it with the "mystery of iniquity" already at work (Nero as type), the restrainer as the Roman empire of its own day, the "temple" as the Church, and the lawless one undone simply by Christ's appearing. The historic Orthodox, Catholic, and Reformation traditions have generally followed this soberer line. The drift to watch is the move from a present, recurring spirit of lawlessness that Christ will finally overthrow, to an elaborate datable script the early church never knew. (See the letters The Antichrist, Is a Third Temple Coming?, and Eschatology at a Glance.)
