I do believe there was another reason why these laws were given to the Gentiles. Again, the context is worship. They could not bring their pagan practices into a Messianic worship experience. There is a lot of freedom when it comes to worship: you can dance, shout, be silent, sing, etc. But you cannot drink blood or bring meat that was sacrificed to a Roman god to the potluck! [4]
These were expressions from paganism that could not coexist in the ecclesia. There are certain things that are not a matter of worship preference but sin. The Hebrew Bible says that the life of the creature is in the blood, and the blood is for atonement. “I will set my face against any Israelite or any foreigner residing among them who eats blood, and I will cut them off from the people. You must not eat the blood of any creature because the life of every creature is its blood; anyone who eats it must be cut off.” (Le 17:10, 14).
But pagans would use blood in horrific ways, which was an abomination.
In the Taurobolium, a bull sacrifice practiced from about AD 160 in the Mediterranean cult of the Great Mother of the Gods. The person dedicating the sacrifice lay in a pit with a perforated board placed over the pit’s opening. A bull was slaughtered above him, and the person in the pit bathed in the blood streaming down.
