Idol feasts and Lord's Supper

Therefore, my dearly beloved, shun (keep clear away from, avoid by flight if need be)
any sort of idolatry (of loving or venerating anything more than God).

I am speaking as to intelligent (sensible) men.
Think over and make up your minds [for yourselves] about what I say.
[I appeal to your reason and your discernment in these matters.]

The cup of blessing [of wine at the Lord’s Supper] upon which we ask [God’s] blessing,
does it not mean [that in drinking it] we participate in and share a fellowship (a communion) in the blood of Christ (the Messiah)?
The bread which we break, does it not mean [that in eating it] we participate in and share a fellowship (a communion) in the body of Christ?

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]?

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].

You cannot drink the Lord’s cup and the demons’ cup.
You cannot partake of the Lord’s table and the demons’ table.

Shall we thus provoke the Lord to jealousy and anger and indignation?
Are we stronger than He [that we should defy Him]?

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 Lord’s and everything that is in it.

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.

Do not let yourselves be [hindrances by giving] an offense to the Jews or to the Greeks or to the church of God [do not lead others into sin by your mode of life];

Just as I myself strive to please [to accommodate myself to the opinions, desires, and interests of others, adapting myself to] all men in everything I do, not aiming at or considering my own profit and advantage, but that of the many in order that they may be saved.
