In these words the apostle confutes the error against which he had cautioned them, and gives the reasons why they should not expect the coming of Christ as just at hand. There were several events previous to the second coming of Christ; in particular, he tells them there would be,I. A general apostasy,
there would come a falling away first, v. 3. By this apostasy we are not to understand a defection in the state, or from civil government, but in spiritual or religious matters, from sound doctrine, instituted worship and church government, and a holy life. The apostle speaks of some very great apostasy, not only of some converted Jews or Gentiles, but such as should be very general, though gradual, and should give occasion to the revelation of rise of
antichrist, that
man of sin. This, he says (
v. 5), he had told them of when he was with them, with design, no doubt, that they should not take offence nor be stumbled at it. And let us observe that no sooner was Christianity planted and rooted in the world than there began to be a defection in the Christian church.
