Why Jehovah commands us to abstain from blood — and what this means today
God told Noah after the Flood: 'Only flesh with its life — its blood — you must not eat.' (Genesis 9:4) Blood is sacred because it represents life itself, and all life belongs to God. This was not just a dietary command — it was a statement about ownership. Life is God's gift; we do not have the right to misuse it.
The Mosaic Law reinforced this principle: 'As for any man of the house of Israel or any foreigner who is residing among you who eats any sort of blood, I will certainly set my face against that person who is eating the blood.' (Leviticus 17:10) The prohibition on blood was among the requirements the Jerusalem council in Acts 15 upheld as binding for all Christians.
The apostolic council's decree in Acts 15:28-29 made clear that abstaining from blood applies to Christians under the new covenant. This is not a ceremonial Jewish law that was abolished — it was explicitly reaffirmed for Gentile believers. Jehovah's Witnesses therefore decline blood transfusions, understanding this to be a matter of obedience to God's command.
Modern medical alternatives to transfusion — cell salvage, volume expanders, and bloodless surgical techniques — have advanced significantly, and many hospitals now offer these options. Choosing to honor God's requirement about blood is an act of faith and trust that God's standards are always in our best interest.
