That's not true in Catholicism and presumably Orthodox Christianity too. They believe the eucharist is literally Jesus' body, even though it tastes like cardboard. The wine is literally Jesus' blood, even though it tastes just like wine.
Exactly, their teaching is vile and loathsome, their practices are degrading and insane. Not kosher.
The words that Jesus spoke, teaching that he received from God like manna from heaven became the flesh of Jesus, a new metaphor for instruction from God, bread from heaven. Hence "The Word became Flesh.", teaching from God freely given through Jesus for the life of the world.
Words that form the Body of Christ's teaching are what give life. Words cannot be handed out and eaten like a cheap snack food. This practice is a brazen desecration of the Actual Body of Christ.
The act of transforming the bread and wine into the body and blood of Jesus is known as transubstantiation.
Thank you. I know. Transubstantiation is just another word for bullshit.
