Those who believe in transubstantiation, that the bread and wine become Jesus’ literal body and blood, base this doctrine on the wording of certain Bible verses. For example, in many Bible translations, Jesus is recorded as saying of the wine: “This is my blood.” (Matthew 26:28) However, Jesus’ words can also be translated as: “This means my blood,” “This represents my blood,” or “This signifies my blood.”f As he had often done, Jesus was teaching by using a metaphor.​—Matthew 13:34, 35.
