There is a command from God somewhere in the first few books of the Bible not to drink the blood of any animal. I can’t remember the exact place. Anyhow, I purchase protein powder for convenience and some brands carry a small amount of “bovine plasma protein”, which is literally blood protein from a cow (powdered, of course). It is full of immunoglobins and agents beneficial for the intestines. Breast milk also contains some similar chemicals. I’ve never consumed it and didn’t want to because of this command.
I know God doesn’t change his mind and if he doesn’t like it, I’m not taking it. But then I remember Paul saying (again not sure exact placement) not to be offended by what we eat, what is sensible for a man to eat is okay for him, and to another for them. What do I do? I just don’t want to consume it because I don’t want God to be angry, but if that’s my reasoning, then I’m following the Law. I’m uncertain.
Deut. 12:23 says, “But be sure you do not eat the blood, because the blood is the life, and you must not eat the life with the meat.” James repeated this in Acts 15:19-20. God won’t be angry if you take the supplement. He has made peace with you. (Colossians 1:19-20) But if it bothers you, don’t take it. There must be other supplements that don’t contain powdered cow’s blood. Paul was referring to eating meat that had been sacrificed to idols, but he also said each man should be convinced in his own mind that what he’s doing is right (Romans 14:5-6).
