That sort of surprised me as well. From the few articles I read, they can eat meat that has the blood properly drained from it. Thus, they wouldn’t eat something like blood pudding or blood sausage. For years, I thought they refrained from transfusions because they interpreted it as a mild form of cannibalism. They weren’t eating flesh but their body would “consume” another person’s blood. Now.... I wonder how they interpret the Last Supper. That is, when Jesus says “take this.. this is my body. Drink this.. this is my blood”.
Well, they have their own mis-translation of the bible which they quote from and that has distorted the Word of God considerably, so they may have edited it out. They also believe that Jesus Christ is just the Archangel Michael, not God.
