Learned a new one today. Jesus ordered that Christians were not to partake of the blood of any living creature, including man. Blood is part of the Soul, which all living things have. ( something else I learned today) In Noah's time the commandant was given and repeated in Mose's time. The New Testament supersedes the laws of Moses. However Jesus repeated the commandment. Acts 15: 28, 29 Acts 21: 25 This command is not to take blood into oneself for any reason, by any means. That would include transfusions. Fortunately there are alternate means to blood for surgery and life threatening events.
