1 Corinthians 10:14-22
14 Therefore, my dear friends, flee from idolatry. 15 I speak to sensible people; judge for yourselves what I say. 16 Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? 17 Because there is one loaf, we, who are many, are one body, for we all share the one loaf.
18 Consider the people of Israel: Do not those who eat the sacrifices participate in the altar? 19 Do I mean then that food sacrificed to an idol is anything, or that an idol is anything? 20 No, but the sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons. 21 You cannot drink the cup of the Lord and the cup of demons too; you cannot have a part in both the Lord’s table and the table of demons. 22 Are we trying to arouse the Lord’s jealousy? Are we stronger than he?
In the previous lesson we spoke of covenant loyalty between Christ and his people. Garland points out how utterly unique that was in Roman Corinth: Pauls insistence on exclusive loyalty to a religion was something uncommon in paganism. People were accustomed to joining in the sacrificial meals of several deities, none of which required an exclusive relationship.
The technical term for mixing parts of a number of religions is syncretism, and it also characterizes many postmodern faith choices. Many contemporary people — even some atheists — blithely chose elements from a smorgasbord of faiths.
To all these pluralistic tendencies, whether ancient or modern, Paul says, Flee from idolatry (1 Cor. 10:14). He has been working toward this conclusion throughout chapters 8-10. In verse 15, Paul appeals, probably without irony, to these sensible people to judge his words carefully.
Paul will demonstrate that the Corinthians have failed to understand the nature of the spiritual community that exists in the sacred meal established by Jesus (i.e. communion) and the religious meals celebrated in idol temples. Obviously, the two questions in verse 16 expect the answer yes. Twice in verse 16 the NIV uses the English word participation to translate the Greek noun koinonia. Thiselton expands that slightly to say communal participation and explains that here it denotes having an active common share in the life, death, resurrection, and presence of Jesus Christ as the Lord who determines the identity and lifestyle of that in which Christians share. That rich meaning is quite different from the mere idea of social fellowship that many evangelical Christians associate with koinonia.
Verse 17 is very difficult because it carries a lot of symbolism. The one loaf is Jesus Christ; recall that Jesus held the bread at the Last Supper and said, “Take and eat; this is my body” (Matt. 26:26). By sharing in the one loaf, we, who are many, are one body (1 Cor. 10:17b). This fact also shows how ridiculous it is for divisions to exist in the Corinthian church.
Even though the final paragraph (verses 18-22) begins with Israel, that is merely a jumping off point to talk about feasts dedicated to idols. Paul begins by establishing that those in Israel who ate the sacrifices were participants (Greek koinonia again) in the altar (1 Cor. 10:18). Some believe verse 18 refers to the God-ordained sacrifices (e.g. Lev. 10:12-15), while others believe this is a description of certain Israelites participating in sacrifices to idols, a practice totally forbidden by God. Either way, the answer to Pauls question is yes; those who eat the sacrifices are participants in the altar.
Verse 19 tells us that idolaters are not actually worshipping a god that exists, so the sacrifices honor no actual god. But at this point, in verse 20, Paul drops the bomb on Corinthian practices! By participating in banquets dedicated to idols, the Corinthians are actually joining themselves to demons; the sacrifices of pagans are offered to demons (1 Cor. 10:20). Idols are nothing, but demons are real indeed!
Paul tells the Corinthians they cannot have it both ways. They cannot be partners with demons and united to Christ at the same time! (1 Cor. 10:21). If they continue down that path, the jealousy of the Lord will utterly sweep them away (1 Cor. 10:22).
