1 Corinthians 10:18

Behold Israel after the flesh Second reason (see 1 Corinthians 10:16). As the Christian sacrificial feasts, so are those of the Jews.

are not they which eat of the sacrifices partakers of the altar? "In a strict and peculiar sense the altar having part of the animal, the partaker another part." Dean Alford. The word here translated partakersis not the same as in the last verse. It is, like the word translated communion, from κοινὸς, common, and implies that the altar and the worshipper share together in the victim. Bengel remarks that "he to whom anything is offered, the things which are offered, the altar on which they are offered," and he might have added those who offer them, "have communion with each other." If, therefore, any one knowingly rakes of an idol sacrifice, as such(it would seem that some went so as to contend that Christians might do so), he makes himself responsible for the worship of the idol, and all the evils with which that worship is connected.
