Did Jesus or the Twelve ever use the term 'the Body of Christ'?
No. The term 'the Body of Christ' was never used by Jesus or the Twelve. It is associated with the Gospel of Grace revealed through Paul, who refers to the called-out group as the Body of Christ. They did not know or use the term; Jesus knew but did not reveal it.
Les teaches that the Gospel of the Kingdom was for Jew only, with nothing for the Gentile. When Israel rejected the Gospel of the Kingdom and the King, and crucified Him, God turned to Saul of Tarsus, the Apostle Paul, who proclaimed the Gospel of Grace. Through that preaching, instead of calling out a covenant people such as Israel, God is calling out what Paul refers to as the Body of Christ. Les emphasizes that Jesus or the Twelve never use the term 'the Body of Christ'—never. He challenged people for years to find it, and no one ever has. They did not know about it and did not use the term. Jesus knew about it, but He never revealed it.
