There is no compelling indication that Jesus was not speaking metaphorically in these passages regarding the body and the blood used to “remember” the sacrifice df our Lord on our behalf. The focus of the Lord’s Supper is to remember what He endured for us, what He gave willingly for us - His body and His blood to pay the price for our sins. Seeing the elements as symbols in no way takes away from the meaning.
