Does the Body of Christ go through the tribulation?

Les explains that since the Body of Christ is called out primarily from among the Gentiles, it has nothing to do with the Old Testament program and therefore nothing to do with the tribulation, because that is tied to the Old Testament primarily for the Jew. He maintains that the Body of Christ is insulated from God's dealings with Israel either before or after, and this is why he teaches the Rapture. The Body of Christ has to be off the scene before God can pick up dealing with Israel. After Israel rejected Messiah, God called out the Body of Christ; it has to be raptured, and then He will yet bring in the tribulation to Israel. Les also points to Romans 11:25 as the triggering mechanism for Christ's coming for the Church, while noting there is no time element.
