It was not wrong to eat meat that pagans had offered in sacrifice to an idol. Any food for which one thanks God thereby becomes acceptable for human consumption, assuming it is wholesome ( 1 Corinthians 10:30; cf. 1 Timothy 4:3-5). This was a very un-Jewish viewpoint coming from a Jew. As earlier in this epistle and elsewhere in his writings, Paul appealed to Scripture for a supporting summary statement ( Psalm 24:1; Psalm 50:12). [source][source][source]
Remember Paul was talking about distinctions based on spiritual issues. In Christianity there is no distinction between kosher (fit) and non-kosher (unfit) food ( Mark 7:19; Acts 10:15). Paul was not talking about distinctions in food based on physical factors such as fat content, calories, and nutritional value. The issue was whether certain foods commend us to or condemn us before God. They do not. [source][source][source]
