28 Yet if anyone should say to you folks, "This is [meat; something] offered in a temple or a sacred sacrifice to an idol," do not proceed to eat [it], because of that person pointing it out (disclosing it) and [on account of] the conscience.
1 Corinthians 10:28 Cross References - JMNT
Matthew 6:31-32
31 "Therefore, you folks should not fret, be anxious, be full of care or be worrying, constantly saying, 'What can we eat?' or, 'What can we drink?' or, 'What can we put on ourselves to wear?'
32 "You see, the ethnic multitudes (the nations; the pagans; the non-Jews) are habitually in eager pursuit of these things – spending all of their energy in seeking them! After all, your heavenly Father (or: your Father Who inhabits, and can be compared to, the atmosphere) has seen and knows that you folks repeatedly have need for all of these things.
Romans 14:15
15 For instance, if because of solid food (or: the effect of something eaten) your brother is continually made sad (made sorry, distressed or grieved), you are no longer continuing to walk about (= living your life) in accord with (or: down from and on the level of) Love (or: you are not yet habitually walking [your path] in participation with transcendent unity of unambiguous, uniting acceptance toward others). Do not, by your food (or: for your solid food), progressively destroy away (lose by ruining; bring to loss) that person over whom Christ died.
1 Corinthians 8:7
7 Nevertheless, the intimate, experiential knowledge, insight and awareness (gnosis) [of this is] not within everyone (or: all folks). Now some – by joint custom and mutual habit pertaining to the idol, until right now – are continually eating [food] as something sacrificed to an idol, and their conscience being weak is repeatedly being stained (polluted; defiled).
1 Corinthians 8:10-13
10 For if anyone should see you – the one presently having (continuing in holding and in possession of) experiential, intimate knowledge or insight (gnosis) – repeatedly lying down (habitually reclining at a meal during a sacrificial banquet) within an idol's temple dining room, will not his conscience – he being a weak person – be progressively "built up" unto the [rationalizations for him] to be habitually eating [foods] having been offered in sacrifice to idols?
11 You see, [thus] the one being habitually weak is being progressively loosed away and ruined (or: is destroying himself) by (with; in; for) your "knowledge" (gnosis) – the brother (= fellow believer; member of the family) because of whom Christ died!
12 Now by continually doing error (repeatedly failing and missing the goal; habitually sinning or acting amiss) unto the brothers (or: So while from time to time [casting this] mistake into the [hearts] of [your] fellow believers) in this way, and repeatedly beating or striking and thus wounding their weak conscience, you folks are constantly doing error (failing; sinning; acting amiss) unto Christ!
13 Because of this very reason, if food is habitually being a snare-stick to entrap my brother (= fellow believer; family member) or cause him to stumble, I should under no circumstances eat meat (flesh [i.e., referring to what was offered to idols]) – on into the Age! – so that I should not be a snare-stick to entrap my brother (or: group member) or cause him to stumble.
1 Corinthians 10:26
26 for, "the earth (or: land) and the results of its filling (entire contents; that which fills it up) belong to and have their origin in the Lord [= Yahweh]." [Ps: 24:1; etc.]
