This is becoming puerile. So for fifteen hundred years the followers the Catholic Church including those who assembled the books of the Bible using early Church beliefs and practices, the saint sand martyrs all got it wrong because by “your” interpretation Christ created an absurdity!
I don’t think it’s “puerile” at all. If the wine and wafers are changed into the actual blood and body of Christ, as your church believes that is exactly what happened at the Last Supper, then your church believes and teaches that Christ shed His blood the night before He went to the Cross to shed His blood. Unless you can give me a clearer explanation of the catholic belief.
