Ye know - This verse is regarded by many as a parenthesis. But it is not necessary to suppose that it is so, or that it does not cohere with that which follows. The design seems to be to remind them of their former miserable condition as idolaters, in order to make them more sensible of their advantages as Christians, and that they might be led more highly to appreciate their present condition. Paul often refers Christians to their former condition, to excite in them gratitude for the mercies that God has conferred on them in the gospel; see the note at 1-Corinthians 6:11, compare Romans 6:17; Ephesians 2:11-12; Titus 3:3.
That ye were Gentiles - Heathen; worshippers of idols. The idea is, that they were pagans; that they had no knowledge of the true God, but were sunk in miserable superstition and idolatry.
Carried away - Led along; that is, deluded by your passions, deluded by your priests, deluded by your vain and splendid rites of worship. The whole system made an appeal to the senses, and "bore along" its votaries as if by a foreign and irresistible impulse. The word which is used ἀπαγόμενοι apagomenoi conveys properly the idea of being carried into bondage, or being led to punishment, and refers here doubtless to the strong means which had been used by crafty politicians and priests in their former state to delude and deceive them.
Unto these dumb idols - These idols which could not speak - an attribute which is often given to them, to show the folly of worshipping them; Psalm 115:5; Psalm 135:15; Habakkuk 2:18-19. The ancient priests and politicians deluded the people with the notion that oracles were uttered by the idols whom they worshipped, and thus they maintained the belief in their divinity. The idea of Patti here seems to be:
(1) That their idols never could have uttered the oracles which were ascribed to them, and consequently that they had been deluded.
(2) that these idols could never have endowed them with such spiritual privileges as they now had, and consequently that their present state was far preferable to their former condition.
Even as ye were led - Were led by the priests in the temples of the idols. They were under strong delusions and the arts of cunning and unprincipled people. The idea is, that they had been under a strong infatuation, and were entirely at the control of their spiritual leaders - a description remarkably applicable now to all forms of imposture in the world, No system of paganism consults the freedom and independence of the mind of man; but it is everywhere characterized as a system of "power," and not of "thought;" and all its arrangements are made to secure that power without an intelligent assent of the understanding and the heart.

Ye were Gentiles - Previously to your conversion to the Christian faith; ye were heathens, carried away, not guided by reason or truth, but hurried by your passions into a senseless worship, the chief part of which was calculated only to excite and gratify animal propensities.
Dumb idols - Though often supplicated, could never return an answer; so that not only the image could not speak, but the god or demon pretended to be represented by it could not speak: a full proof that an idol was nothing in the world.

(2) Ye know that ye were (b) Gentiles, carried away unto these dumb idols, even as ye were led.
(2) He reproves the same by comparing their former state with that in which they were at this time, being endued with those excellent gifts.
(b) As touching God's service and the covenant, mere strangers.

Ye know that ye were Gentiles,.... That is, by religion; hence the Syriac version renders it "profane" persons, given up to wickedness, bigotry, and superstition; for by nation they were Gentiles still; and which must be understood of one part of this church only; for some of them were Jews, as is clear from many passages in the epistle to this church, and practices referred to. This the apostle observes to humble them, by putting them in mind of what they had been formerly; they were born and brought up in the Heathen religion, when they knew not the true God, much less had any knowledge of Christ, and still less of the Spirit of God; and therefore if they were favoured with any of his gifts, these must be owing to his grace, and not to their deserts, and therefore they ought not to glory: he adds, with the same view,
carried away unto these dumb idols; to idols that were nothing in the world, had no divinity in them, as he had before asserted; to dumb ones, that had mouths, but could not speak, the oracles that were delivered from them, being spoken not by them, but were either satanical delusions, or the jugglings of a priest; to these they were carried by the power of Satan, the influence of their priests, and the orders of their magistrates, to consult them as oracles, to pay their devotions to them, and do them service:
even as ye were led; that is, to these dumb idols; the Syriac adds, , "without any difference", not being able to distinguish between these and the true God; and to whom they were led as brute beasts were, that were sacrificed unto them, or as blind men are led by the blind, as they were by their blind and ignorant priests; and therefore, if they had now received the Spirit, and his gifts, they ought to ascribe the whole to the free grace of God, and be humble under a sense of their unworthiness.

(Ephesians 2:11).
that ye were--The best manuscripts read, "That WHEN ye were"; thus "ye were" must be supplied before "carried away"--Ye were blindly transported hither and thither at the will of your false guides.
these dumb idols--Greek, "the idols which are dumb"; contrasted with the living God who "speaks" in the believer by His Spirit (1-Corinthians 12:3, &c.). This gives the reason why the Corinthians needed instruction as to spiritual gifts, namely, their past heathen state, wherein they had no experience of intelligent spiritual powers. When blind, ye went to the dumb.
as ye were led--The Greek is, rather, "as ye might (happen to) be led," namely, on different occasions. The heathen oracles led their votaries at random, without any definite principle.

Ye were heathens - Therefore, whatever gifts ye have received, it is from the free grace of God. Carried away - By a blind credulity. After dumb idols - The blind to the dumb; idols of wood and stone, unable to speak themselves, and much more to open your mouths, as God has done. As ye were led - By the subtlety of your priests.
