I Corinthians 8:4

As concerning, &c.--resuming the subject begun in Co1 8:1, "As touching," &c. idol is nothing--has no true being at all, the god it represents is not a living reality. This does not contradict Co1 10:20, which states that they who worship idols, worship devils; for here it is the GODS believed by the worshippers to be represented by the idols which are denied to have any existence, not the devils which really under the idols delude the worshippers. none other God--The oldest manuscripts omit the word "other"; which gives a clearer sense.

In this passage he shows the vanity of idols: As to the eating of things that have been sacrificed to idols, we know that an idol is nothing in the world; or, there is no idol in the world; or, an idol can do nothing in the world: for the form of expression in the original is elliptical.

John 1:3; Col 1:16; Heb 1:2).
