The Precious Body and Blood in Scripture

Matt. 26:29; Mark 14:25; Luke 22:18 – Jesus says He will not drink of the “fruit of the vine” until He drinks it new in the kingdom. Some Protestants try to use this verse (because Jesus said “fruit of the vine”) to prove the wine cannot be His blood. But the Greek word for fruit is “genneema” which literally means “that which is generated from the vine.” In John 15:1,5 Jesus says “I am the vine.” So “fruit of the vine” can also mean Jesus’ blood. In 1 Cor. 11:26-27, Paul also used “bread” and “the body of the Lord” interchangeably in the same sentence. Also, see Matt. 3:7;12:34;23:33 for examples were “genneema” means “birth” or “generation.”
