Yeah, I understand what Catholics believe and have studied it. Catholics still consider it the real physical blood of Jesus. What Catholics won’t acknowledge is that eating blood was and still is commanded by God NOT to be eaten. Jesus was born under the law. He lived prior to His death and resurrection in submission to those Old Testament laws. If Jesus ate blood and encouraged His apostles to do so He sinned against the law. That makes Jesus into a sinner and not the sinless man scripture speaks of. The admonition to not eat blood was reiterated by the apostles for the New Testament saints in Acts 15.
Well I guess I can only answer by saying Catholics have very different beliefs than you have expressed.
Let me see how can I say this without sounding rude. If you, as Protestant, do not want to believe that, or any other Catholic teaching, then don’t. I would never have any illusions about somehow or another being able to convince you that the teachings of the Catholic Church are true. As I told MamaB, that is not why I come on this site.
