I Corinthians 10:18

Israel after the flesh--the literal, as distinguished from the spiritual, Israel (Rom 2:29; Rom 4:1; Rom 9:3; Gal 4:29). partakers of the altar--and so of God, whose is the altar; they have fellowship in God and His worship, of which the altar is the symbol.

In this chapter the apostle prosecutes the argument at the close of the last, and, I. Warns the Corinthians against security, by the example of the Jews, who, notwithstanding their profession and privileges, were terribly punished of God for their many sins, their history being left upon record for the admonition of Christians (Co1 10:1-14). II. He resumes his former argument (Co1 8:1-13), about eating things offered to idols; and shows that it was utterly inconsistent with true Christianity, that it was downright gross idolatry, to eat them as things offered to idols; it is having fellowship with devils, which cannot consist with having fellowship with God (Co1 10:15-22). III. He lets them yet know that though they must not eat of things sacrificed to idols as such, and out of any regard to the idol, yet they might buy such flesh in the markets, or eat it at the table of heathen acquaintances, without asking any questions; for that the heathens' abuse of them did not render the creatures of God unfit to be the food of his servants. Yet liberty of this kind must be used with a due regard to weak consciences, and no offence given by it t Jew nor Gentile, nor to the church of God (Co1 10:23 to the end).
