Jesus called the cup wine. He said so Himself. I believe Him.
The apostles didn't think that the cup was blood. Peter had never eaten anything unclean by his own words in Acts 10:14. Eating of blood is strictly prohibited by God in Scripture because the blood is for atonement. It is a command reiterated in the decision of the Council of Jerusalem in Acts 15.
No, the apostles didn't teach the eating of blood and neither did Jesus.
You lie.
