That blood doctrine is a terrible one, dangerous. I'll stand to be corrected, but from what I've understand a blood transfusion procedure was not performed until within the last century or so, I think I'm not sure of the exact timeline I read it a few years ago.
So, if that's the case, that scripture in Acts was referring simply to injesting/eating blood. How in hell would someone be able to attempt a blood transfusion in bible times is just beyond me.
