Shall be caught up. — “Our Assumption,” as Bishop Ellicott well calls it. The spiritualising of our natural bodies without death, as described in 1 Corinthians 15:50, et seq., will enable us to be “caught up” equally well with, and in company with (both of which thoughts are included in “together with”), the resurgent dead. “Clouds” and “air” will be support enough for material so immaterial. Theodoret says, “He showeth the greatness of the honour: as the Master Himself was taken up upon a shining cloud, so also they that have believed in Him.” The absolute equality, then, of quick and dead is proved.
To meet the Lord in the air. — St. Chrysostom says:” When the King cometh into a city, they that are honourable proceed forth to meet him, but the guilty await their judge within.” The phrase “in the air” certainly does not mean “heaven.” The word “air”) in itself properly signifies the lower, denser, grosser atmosphere, in which the powers of darkness reign (Ephesians 2:2); but here it is only used in contrast with the ground, and means “on the way from Heaven whence He comes,” of course not to dwell there, but to accompany Him to His Judgment-seat on the earth.
And so. — Now that St. Paul has settled the question of disparity between the dead and the living, he does not think it necessary to describe what is immediately to follow; that, the Thessalonians were sure to know (see Hebrews 6:2): it only remains to say that having once rejoined the Lord, they would never be parted from Him.
