And then shall that Wicked One be revealed, whom the Lord shall consume with the breath of his mouth, and shall destroy with the brightness of his coming:
All Commentaries on 2 Thessalonians 2:8 Go To 2 Thessalonians 2
George Leo Haydock
AD 1849
Spirit of his mouth St. Paul makes use of this expression, to show the ease with which God can put down the most powerful from his seat. He does it likewise to give the Thessalonians a right notion of the man of sin. For as he before told them, he would cause himself to be adored, they might have imagined him more upon an equality with the Almighty. These words, however, quite take away that meaning. He shall strike the earth with the rod of his mouth, and with the breath of his lips he shall slay the wicked. (Isaias xi. 4.) (Calmet)
