"The similarity between grape juice and blood.......Horus was a wine god, so too was dionysus; so too was the Jesus of the Gospels."
An important inclusion of wine on at least 1 more account, which virtually ties Judaism and Greek Religion sybolically to Christianity would be:
1) Jesus (Exodus’ lamb of God) shed his blood (wine) as a libation (atonement) to the gods.
“Then He took the cup, and gave thanks, and gave it to them, saying, "Drink from it, all of you. For this is My blood of the new covenant, which is shed (ekcheo:pour out) for many for the remission of sins.”
"Then likewise he sprinkled with blood both the tabernacle and all the vessels of the ministry. And according to the law almost all things are purified (cleansed) with blood, and without shedding of blood there is no remission."
Just as the ‘spiritually dead’ are raised to life by drinking Jesus’ shed blood, indeed it was the pouring of the ram's blood (and subsequent drinking) into the river of Hades that enabled the Dead of Hades to speak to Odysseus in Homer’s Odyssey. Tiresias and the others could only speak AFTER drinking the blood offering.
Notice the mingling of the blood and water, i.e., wine and water.
Blood (like water) has a cleansing effect.
Water cleanses the outside (baptism) from dirt, wine (which looks and acts like blood) cleanses the inside from sin.
Consider another quote from Homer according to Plato:
“The gods, too, may be turned from their purpose ; and men pray to them and avert their wrath by sacrifices and soothing entreaties, and by libations and the odor of fat, when they have sinned and trangressed.”
