they all . . . damned--rather as Greek, "that all," &c. He here states the general proposition which applies specially to Antichrist's adherents. Not all in the Church of Rome, or other anti-Christian systems, shall be damned, but only "all who believed not the truth," when offered to them, "but had pleasure in unrighteousness" (Rom 1:32; Rom 2:8).

The apostle is very careful to hinder the spreading of an error into which some among them had fallen concerning the coming of Christ, as being very near (Th2 2:1-3). Then he proceeds to confute the error he cautioned them against, by telling them of two great events that were antecedent to the coming of Christ - a general apostasy, and the revelation of antichrist, concerning whom the apostle tells them many remarkable things, about his name, his character, his rise, his fall, his reign, and the sin and ruin of his subjects (Th2 2:4-12). He then comforts them against the terror of this apostasy, and exhorts them to stedfastness (Th2 2:13-15). And concludes with a prayer for them (Th2 2:16, Th2 2:17).
