For if someone should see you who have knowledge, dining in an idol’s temple, will not the conscience (syneidēsis | συνείδησις | nom sg fem) of the one who is weak be emboldened to eat food sacrificed to idols?
However, not everyone has this knowledge. But some, because in former times they were involved with idols, eat this food as though it were an idol sacrifice, and thus their conscience (syneidēsis | συνείδησις | nom sg fem), being weak, is defiled.
They show that the work of the law is written on their hearts, their conscience (syneidēseōs | συνειδήσεως | gen sg fem) bearing witness and their conflicting thoughts accusing or else defending them,
Looking intently at the council, Paul said, “My brothers, I have lived in all good conscience (syneidēsei | συνειδήσει | dat sg fem) before God up to this day.”
