{Now concerning things sacrificed to idols} (peri de t(936e)
eid(936c)othut(936e)). Plainly the Corinthians had asked also about this
problem in their letter to Paul ( 7:1 ). This compound adjective
(eid(936c)on, idol, 	hutos, verbal adjective from 	hu(935c), to
sacrifice) is still found only in the N.T. and ecclesiastical
writers, not so far in the papyri. We have seen this problem
mentioned in the decision of the Jerusalem Conference ( Ac 15:29  21:25 ). The connection between idolatry and impurity was very
close, especially in Corinth. See both topics connected in  Re
2:14,20 . By eid(936c)othuta was meant the portion of the flesh
left over after the heathen sacrifices. The heathen called it
hierothuton ( 1Co 10:28 ). This leftover part "was either eaten
sacrificially, or taken home for private meals, or sold in the
markets" (Robertson and Plummer). What were Christians to do
about eating such portions either buying in the market or eating
in the home of another or at the feast to the idol? Three
questions are thus involved and Paul discusses them all. There
was evidently difference of opinion on the subject among the
Corinthian Christians. Aspects of the matter come forward not
touched on in the Jerusalem Conference to which Paul does not
here allude, though he does treat it in  Ga 2:1-10 . There was
the more enlightened group who acted on the basis of their
superior knowledge about the non-existence of the gods
represented by the idols. {Ye know that we all have knowledge}
(oidamen hoti pantes gn(9373)in echomen). This may be a quotation
from the letter (Moffatt, _Lit. of N.T._, p. 112). Since their
conversion to Christ, they know the emptiness of idol-worship.
Paul admits that all Christians have this knowledge (personal
experience, gn(9373)is), but this problem cannot be solved by
knowledge.
