The sticking point in this passage is meat. You see, most of the meat in Corinth came from pagan temples. The choicest cuts started off as a sacrifices to the various gods and, since the gods didn't eat much, the meat ended for sale in the market. It also seems that some temples even operated their own open-air restaurants. They wrote to Paul for an answer.
Christians are certainly free to eat meat offered to idols.
We know that idols are nothing really. They're just wood, stone, and metal. There are no other gods. There is only one God, the God of Abraham, Isaac, and Jacob, the God who is the Father of Jesus Christ, the head of the Church. Christians who understand this are free to eat this meat.
