Prohibition in O.T. Several passages in the Old Testament strongly prohibit the "eating of blood and fat."
...you must not eat flesh with life, that is to say, blood in it. (Genesis 9:4-5)
This is a perpetual law for all your descendants wherever you may live: that you will not eat either fat or blood. (Leviticus 3:17)
You will not consume the blood of any creature, for the life of every creature is its blood, and anyone who consumes it will be cut off. (Leviticus 17:14) (See also Deuteronomy 12:16, 12:23-28)
Therefore say to them, "This is what the Sovereign LORD says, 'Since you eat meat with the blood still in it...should you then possess the land?' (Ezekiel 33:25)
It is my judgment, therefore, that we should not make it difficult for the nations who are turning to God. Instead, we should write to them to abstain from food polluted by idols...from the meat of strangled animals and from blood. (Acts 15:19-20)
This prohibition against eating (or drinking) blood was a universal one, covering the whole Old Testament, and leaping over into the New Testament. Both Jews and the nations (Gentiles)were all admonished to abstain.
Early Church The Early Church sent a letter to the churches declaring this position...but the question begs to be asked...is this prohibition still in effect? Are Christians in the twenty-first century still to observe this restriction?
If so, where do menus with gravies, sausages, hamburgers, casseroles, stews, etc. stand? How is a modern Christian to interpret the Bible concerning this? The other restrictions against "food polluted by idols, sexual immorality, etc." are still observed by most local churches. So ought this one against blood also be observed?
Notice that one of the reasons God removed the Israelites from their Promised Land was because of their failure to observe this regulation!
