Lord’s Supper: Consuming Christ? (John 6:55)

Our Lord uses very strong language about finding life and having life in him. Christ tells us that need to eat his flesh and his blood. He promises that as we eat of his flesh and blood we are assured that we will have true life that will never end. So, does this mean that every time that we have the Lord’s supper that we consume Christ’s body and blood? Does this mean that every time we come together that Christ is re-sacrificed? What does Christ mean by this language?
