For we [no matter how] numerous we are, are one body, because we all partake of the one Bread [the One Whom the communion bread represents].
Consider those [physically] people of Israel. Are not those who eat the sacrifices partners of the altar [united in their worship of the same God]? [Lev_7:6]
What do I imply then? That food offered to idols is [intrinsically changed by the fact and amounts to] anything or that an idol itself is a [living] thing?
No, I am suggesting that what the pagans sacrifice they offer [in effect] to demons (to evil spiritual powers) and not to God [at all]. I do not want you to fellowship and be partners with diabolical spirits [by eating at their feasts]. [Deu_32:17]
You cannot drink the Master’s cup and the demons’ cup. You cannot partake of the Master’s table and the demons’ table.
Shall we thus provoke the Master to jealousy and anger and indignation? Are we stronger than He [that we should defy Him]? [Deu_32:21; Ecc_6:10; Isa_45:9]
All things are legitimate [permissible–and we are free to do anything we please], but not all things are helpful (expedient, profitable, and wholesome). All things are legitimate, but not all things are constructive [to character] and edifying [to spiritual life].
Let no one then seek his own good and advantage and profit, but [rather] each one of the other [let him seek the welfare of his neighbor].
[As to meat offered to idols] eat anything that is sold in the meat market without raising any question or investigating on the grounds of conscientious scruples, for the [whole] earth is the Master’s and everything that is in it. [Psa_24:1; Psa_50:12]
In case one of the unbelievers invites you to a meal and you want to go, eat whatever is served to you without examining into its source because of conscientious scruples.
But if someone tells you, This has been offered in sacrifice to an idol, do not eat it, out of consideration for the person who informed you, and for conscience’s sake—I mean for the sake of his conscience, not yours, [do not eat it]. For why should another man’s scruples apply to me and my liberty of action be determined by his conscience?
If I partake [of my food] with thankfulness, why am I accused and spoken evil of because of that for which I give thanks?
So then, whether you eat or drink, or whatever you may do, do all for the honor and glory of God.
