Remember I mentioned that some commentators call the peace offering a communion sacrifice, which is the term Paul uses here regarding the bread and the wine. We might shy away from the term because of how it has been appropriated, but it means, to be in close fellowship or participation with. This passage teaches that a sacrificial meal joins a person in fellowship with the object of that sacrifice, whether the true God or an idol (demon). The Passover unites us with God through a sacrificial meal. It also unites us with others, and we become one because we partake of that one bread, which is Christ.
