<p>10:26 <em>For the earth is the Lord's and the fullness of it- </em>Everything is God's. There is only one God, and so the fact the meat had been previously offered to an idol did not mean that it belonged to an idol, and that eating such meat with that history implied fellowshipping the idol. It was eating the meat in the idol's temple as a conscious act of fellowship with the idol which was wrong- hence the Lord Jesus Himself condemns eating meat offered to idols in his letters to the churches in Rev. 2:14,15,20-25. Note that in each of those cases, He links such eating with sexual immorality. Eating with the idol and then sleeping with the cult prostitutes was pure paganism, and typical of Corinthian religiosity. And it had entered the church at Corinth.</p>
