2 Corinthians 10:5

"Casting down imaginations." First giving emphasis by the figure, and then by this additional expression declaring the spiritual character of the warfare. For these strongholds besiege souls, not bodies. Whence they are stronger than the others, and therefore also the weapons they require are mightier. But by strongholds he means the Grecian pride, and the strength of their sophisms and their syllogisms. But nevertheless, 'these weapons,' he says, 'confounded every thing that stood up against them; for they cast down imaginations, And every high thing that is exalted against the knowledge of God.' He persisted in the metaphor that he might make the emphasis greater. 'For though there should be strongholds,' he saith, 'though fortifications, though any other thing soever, they yield and give way before these weapons.'

"And bringing every thought into captivity to the obedience of Christ." And yet the name, "captivity," hath an ill sound with it; for it is the destruction of liberty. Wherefore then has he used it? With a meaning of its own, in regard to another point. For the word "captivity" conveys two ideas, the loss of liberty, and the being so violently overpowered as not to rise up again. It is therefore in respect to this second meaning that he took it. As when he shall say "I robbed other churches," he does not intend the taking stealthily, but the stripping and taking their all, so also here in saying, "bringing into captivity." For the fight was not equally maintained, but he conquered with great ease. Wherefore he did not say, 'we conquer and have the better,' only; but 'we even bring "into captivity;"' just as above, he did not say, 'we advance engines against the "strongholds:"' but, 'we cast them down, for great is the superiority of our weapons." For we war not with words,' he saith, but with deeds against words, not with fleshly wisdom, but with the spirit of meekness and of power. How was it likely then I should hunt after honor, and boast in words, and threaten by letters;' (as they accused him, saying, "his letters are weighty,") 'when our might lay not in these things?' But having said, "bringing every thought into captivity to the obedience of Christ," because the name of "captivity" was unpleasant, he presently afterwards put an end to the metaphor, saying, "unto the obedience of Christ:" from slavery unto liberty, from death unto life, from destruction to salvation. For we came not merely to strike down, but to bring over to the truth those who are opposed to us.
